I have this input element:
<input type="text" class="textfield" value="" id="subject" name="subject">
Then I have some other elements, like other tag's & <textarea> tag's, etc...
When the user clicks on the <input id="#subject">, the page should scroll to the page's last element, and it should do so with a nice animation (It should be a scroll to bottom and not to top).
The last item of the page is a submit button with #submit:
<input type="submit" class="submit" id="submit" name="submit" value="Ok, Done.">
The animation should not be too fast and should be fluid.
I am running the latest jQuery version. I prefer to not install any plugin but to use the default jQuery features to achieve this.
Assuming you have a button with the id button, try this example:
$("#button").click(function() {
$([document.documentElement, document.body]).animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 2000);
});
I got the code from the article Smoothly scroll to an element without a jQuery plugin. And I have tested it on the example below.
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script>
$(document).ready(function (){
$("#click").click(function (){
$('html, body').animate({
scrollTop: $("#div1").offset().top
}, 2000);
});
});
</script>
<div id="div1" style="height: 1000px; width 100px">
Test
</div>
<br/>
<div id="div2" style="height: 1000px; width 100px">
Test 2
</div>
<button id="click">Click me</button>
</html>
jQuery .scrollTo(): View - Demo, API, Source
I wrote this lightweight plugin to make page/element scrolling much easier. It's flexible where you could pass in a target element or specified value. Perhaps this could be part of jQuery's next official release, what do you think?
Examples Usage:
$('body').scrollTo('#target'); // Scroll screen to target element
$('body').scrollTo(500); // Scroll screen 500 pixels down
$('#scrollable').scrollTo(100); // Scroll individual element 100 pixels down
Options:
scrollTarget: A element, string, or number which indicates desired scroll position.
offsetTop: A number that defines additional spacing above scroll target.
duration: A string or number determining how long the animation will run.
easing: A string indicating which easing function to use for the transition.
complete: A function to call once the animation is complete.
If you are not much interested in the smooth scroll effect and just interested in scrolling to a particular element, you don't require some jQuery function for this. Javascript has got your case covered:
https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView
So all you need to do is: $("selector").get(0).scrollIntoView();
.get(0) is used because we want to retrieve the JavaScript's DOM element and not the JQuery's DOM element.
UPDATE
now is possible to scroll with animation, passing scroll options (see MDN). You can even control the block position. It seems to have large support, except for Safari
$("selector").get(0).scrollIntoView({behavior: 'smooth'});
This is achievable without jQuery:
document.getElementById("element-id").scrollIntoView();
Using this simple script
if($(window.location.hash).length > 0){
$('html, body').animate({ scrollTop: $(window.location.hash).offset().top}, 1000);
}
Would make in sort that if a hash tag is found in the url, the scrollTo animate to the ID. If not hash tag found, then ignore the script.
jQuery(document).ready(function($) {
$('a[href^="#"]').bind('click.smoothscroll',function (e) {
e.preventDefault();
var target = this.hash,
$target = $(target);
$('html, body').stop().animate( {
'scrollTop': $target.offset().top-40
}, 900, 'swing', function () {
window.location.hash = target;
} );
} );
} );
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul role="tablist">
<li class="active" id="p1">Section 1</li>
<li id="p2">Section 2</li>
<li id="p3">Section 3</li>
</ul>
<div id="pane1"></div>
<div id="pane2"></div>
<div id="pane3"></div>
This is the way I do it.
document.querySelector('scrollHere').scrollIntoView({ behavior: 'smooth' })
Works in any browser.
It can easily be wrapped into a function
function scrollTo(selector) {
document.querySelector(selector).scrollIntoView({ behavior: 'smooth' })
}
Here is a working example
$(".btn").click(function() {
document.getElementById("scrollHere").scrollIntoView( {behavior: "smooth" })
})
.btn {margin-bottom: 500px;}
.middle {display: block; margin-bottom: 500px; color: red;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="btn">Scroll down</button>
<h1 class="middle">You see?</h1>
<div id="scrollHere">Arrived at your destination</div>

The solution by Steve and Peter works very well.
But in some cases, you may have to convert the value to an integer. Strangely, the returned value from $("...").offset().top is sometimes in float.
Use: parseInt($("....").offset().top)
For example:
$("#button").click(function() {
$('html, body').animate({
scrollTop: parseInt($("#elementtoScrollToID").offset().top)
}, 2000);
});
A compact version of "animate" solution.
$.fn.scrollTo = function (speed) {
if (typeof(speed) === 'undefined')
speed = 1000;
$('html, body').animate({
scrollTop: parseInt($(this).offset().top)
}, speed);
};
Basic usage: $('#your_element').scrollTo();
With this solution you do not need any plugin and there's no setup required besides placing the script before your closing </body> tag.
$("a[href^='#']").on("click", function(e) {
$("html, body").animate({
scrollTop: $($(this).attr("href")).offset().top
}, 1000);
return false;
});
if ($(window.location.hash).length > 1) {
$("html, body").animate({
scrollTop: $(window.location.hash).offset().top
}, 1000);
}
On load, if there is a hash in the address, we scroll to it.
And - whenever you click an a link with an href hash e.g. #top, we scroll to it.
##Edit 2020
If you want a pure JavaScript solution: you could perhaps instead use something like:
var _scrollToElement = function (selector) {
try {
document.querySelector(selector).scrollIntoView({ behavior: 'smooth' });
} catch (e) {
console.warn(e);
}
}
var _scrollToHashesInHrefs = function () {
document.querySelectorAll("a[href^='#']").forEach(function (el) {
el.addEventListener('click', function (e) {
_scrollToElement(el.getAttribute('href'));
return false;
})
})
if (window.location.hash) {
_scrollToElement(window.location.hash);
}
}
_scrollToHashesInHrefs();
If you are only handling scrolling to an input element, you can use focus(). For example, if you wanted to scroll to the first visible input:
$(':input:visible').first().focus();
Or the first visible input in an container with class .error:
$('.error :input:visible').first().focus();
Thanks to Tricia Ball for pointing this out!
Easy way to achieve the scroll of page to target div id
var targetOffset = $('#divID').offset().top;
$('html, body').animate({scrollTop: targetOffset}, 1000);
If you want to scroll within an overflow container (instead of $('html, body') answered above), working also with absolute positioning, this is the way to do :
var elem = $('#myElement'),
container = $('#myScrollableContainer'),
pos = elem.position().top + container.scrollTop() - container.position().top;
container.animate({
scrollTop: pos
}
After finding the way to get my code work, I think I should make thing a bit clear:
For using:
$('html, body').animate({
scrollTop: $("#div1").offset().top
}, 2000);
you need to be on top of the page since $("#div1").offset().top will return different numbers for different positions you scroll to. If you already scrolled out of the top, you need to specify the exact pageY value (see pageY definition here: https://javascript.info/coordinates).
So now, the problem is to calculate the pageY value of one element. Below is an example in case the scroll container is the body:
function getPageY(id) {
let elem = document.getElementById(id);
let box = elem.getBoundingClientRect();
var body = document.getElementsByTagName("BODY")[0];
return box.top + body.scrollTop; // for window scroll: box.top + window.scrollY;
}
The above function returns the same number even if you scrolled somewhere. Now, to scroll back to that element:
$("html, body").animate({ scrollTop: getPageY('div1') }, "slow");
Animations:
// slide to top of the page
$('.up').click(function () {
$("html, body").animate({
scrollTop: 0
}, 600);
return false;
});
// slide page to anchor
$('.menutop b').click(function(){
//event.preventDefault();
$('html, body').animate({
scrollTop: $( $(this).attr('href') ).offset().top
}, 600);
return false;
});
// Scroll to class, div
$("#button").click(function() {
$('html, body').animate({
scrollTop: $("#target-element").offset().top
}, 1000);
});
// div background animate
$(window).scroll(function () {
var x = $(this).scrollTop();
// freezze div background
$('.banner0').css('background-position', '0px ' + x +'px');
// from left to right
$('.banner0').css('background-position', x+'px ' +'0px');
// from right to left
$('.banner0').css('background-position', -x+'px ' +'0px');
// from bottom to top
$('#skills').css('background-position', '0px ' + -x + 'px');
// move background from top to bottom
$('.skills1').css('background-position', '0% ' + parseInt(-x / 1) + 'px' + ', 0% ' + parseInt(-x / 1) + 'px, center top');
// Show hide mtop menu
if ( x > 100 ) {
$( ".menu" ).addClass( 'menushow' );
$( ".menu" ).fadeIn("slow");
$( ".menu" ).animate({opacity: 0.75}, 500);
} else {
$( ".menu" ).removeClass( 'menushow' );
$( ".menu" ).animate({opacity: 1}, 500);
}
});
// progres bar animation simple
$('.bar1').each(function(i) {
var width = $(this).data('width');
$(this).animate({'width' : width + '%' }, 900, function(){
// Animation complete
});
});
In most cases, it would be best to use a plugin. Seriously. I'm going to tout mine here. Of course there are others, too. But please check if they really avoid the pitfalls for which you'd want a plugin in the first place - not all of them do.
I have written about the reasons for using a plugin elsewhere. In a nutshell, the one liner underpinning most answers here
$('html, body').animate( { scrollTop: $target.offset().top }, duration );
is bad UX.
The animation doesn't respond to user actions. It carries on even if the user clicks, taps, or tries to scroll.
If the starting point of the animation is close to the target element, the animation is painfully slow.
If the target element is placed near the bottom of the page, it can't be scrolled to the top of the window. The scroll animation stops abruptly then, in mid motion.
To handle these issues (and a bunch of others), you can use a plugin of mine, jQuery.scrollable. The call then becomes
$( window ).scrollTo( targetPosition );
and that's it. Of course, there are more options.
With regard to the target position, $target.offset().top does the job in most cases. But please be aware that the returned value doesn't take a border on the html element into account (see this demo). If you need the target position to be accurate under any circumstances, it is better to use
targetPosition = $( window ).scrollTop() + $target[0].getBoundingClientRect().top;
That works even if a border on the html element is set.
This is my approach abstracting the ID's and href's, using a generic class selector
$(function() {
// Generic selector to be used anywhere
$(".js-scroll-to").click(function(e) {
// Get the href dynamically
var destination = $(this).attr('href');
// Prevent href=“#” link from changing the URL hash (optional)
e.preventDefault();
// Animate scroll to destination
$('html, body').animate({
scrollTop: $(destination).offset().top
}, 500);
});
});
<!-- example of a fixed nav menu -->
<ul class="nav">
<li>
Item 1
</li>
<li>
Item 2
</li>
<li>
Item 3
</li>
</ul>
Very simple and easy to use custom jQuery plugin. Just add the attribute scroll= to your clickable element and set its value to the selector you want to scroll to.
Like so: <a scroll="#product">Click me</a>. It can be used on any element.
(function($){
$.fn.animateScroll = function(){
console.log($('[scroll]'));
$('[scroll]').click(function(){
selector = $($(this).attr('scroll'));
console.log(selector);
console.log(selector.offset().top);
$('html body').animate(
{scrollTop: (selector.offset().top)}, //- $(window).scrollTop()
1000
);
});
}
})(jQuery);
// RUN
jQuery(document).ready(function($) {
$().animateScroll();
});
// IN HTML EXAMPLE
// RUN ONCLICK ON OBJECT WITH ATTRIBUTE SCROLL=".SELECTOR"
// <a scroll="#product">Click To Scroll</a>
$('html, body').animate(...) does not work for me in the iPhone, Android, Chrome, or Safari browsers.
I had to target the root content element of the page.
$('#cotnent').animate(...)
Here is what I have ended up with:
if (navigator.userAgent.match(/(iPod|iPhone|iPad|Android)/)) {
$('#content').animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 'slow');
}
else{
$('html, body').animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 'slow');
}
All body content wired up with a #content div
<html>
....
<body>
<div id="content">
...
</div>
</body>
</html>
$('html, body').animate({scrollTop:
Math.min(
$(to).offset().top-margintop, //margintop is the margin above the target
$('body')[0].scrollHeight-$('body').height()) //if the target is at the bottom
}, 2000);
To show the full element (if it's possible with the current window size):
var element = $("#some_element");
var elementHeight = element.height();
var windowHeight = $(window).height();
var offset = Math.min(elementHeight, windowHeight) + element.offset().top;
$('html, body').animate({ scrollTop: offset }, 500);
var scrollTo = function($parent, $element) {
var topDiff = $element.position().top - $parent.position().top;
$parent.animate({
scrollTop : topDiff
}, 100);
};
This is Atharva's answer from: https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView.
Just wanted to add if your document is in an iframe, you can choose an element in the parent frame to scroll into view:
$('#element-in-parent-frame', window.parent.document).get(0).scrollIntoView();
I wrote a general purpose function that scrolls to either a jQuery object, a CSS selector, or a numeric value.
Example usage:
// scroll to "#target-element":
$.scrollTo("#target-element");
// scroll to 80 pixels above first element with class ".invalid":
$.scrollTo(".invalid", -80);
// scroll a container with id "#my-container" to 300 pixels from its top:
$.scrollTo(300, 0, "slow", "#my-container");
The function's code:
/**
* Scrolls the container to the target position minus the offset
*
* #param target - the destination to scroll to, can be a jQuery object
* jQuery selector, or numeric position
* #param offset - the offset in pixels from the target position, e.g.
* pass -80 to scroll to 80 pixels above the target
* #param speed - the scroll speed in milliseconds, or one of the
* strings "fast" or "slow". default: 500
* #param container - a jQuery object or selector for the container to
* be scrolled. default: "html, body"
*/
jQuery.scrollTo = function (target, offset, speed, container) {
if (isNaN(target)) {
if (!(target instanceof jQuery))
target = $(target);
target = parseInt(target.offset().top);
}
container = container || "html, body";
if (!(container instanceof jQuery))
container = $(container);
speed = speed || 500;
offset = offset || 0;
container.animate({
scrollTop: target + offset
}, speed);
};
When the user clicks on that input with #subject, the page should
scroll to the last element of the page with a nice animation. It
should be a scroll to bottom and not to top.
The last item of the page is a submit button with #submit
$('#subject').click(function()
{
$('#submit').focus();
$('#subject').focus();
});
This will first scroll down to #submit then restore the cursor back to the input that was clicked, which mimics a scroll down, and works on most browsers. It also doesn't require jQuery as it can be written in pure JavaScript.
Can this fashion of using focus function mimic animation in a better way, through chaining focus calls. I haven't tested this theory, but it would look something like this:
<style>
#F > *
{
width: 100%;
}
</style>
<form id="F" >
<div id="child_1"> .. </div>
<div id="child_2"> .. </div>
..
<div id="child_K"> .. </div>
</form>
<script>
$('#child_N').click(function()
{
$('#child_N').focus();
$('#child_N+1').focus();
..
$('#child_K').focus();
$('#child_N').focus();
});
</script>
I set up a module scroll-element npm install scroll-element. It works like this:
import { scrollToElement, scrollWindowToElement } from 'scroll-element'
/* scroll the window to your target element, duration and offset optional */
let targetElement = document.getElementById('my-item')
scrollWindowToElement(targetElement)
/* scroll the overflow container element to your target element, duration and offset optional */
let containerElement = document.getElementById('my-container')
let targetElement = document.getElementById('my-item')
scrollToElement(containerElement, targetElement)
Written with help from the following SO posts:

Here is the code:
export const scrollToElement = function(containerElement, targetElement, duration, offset) {
if (duration == null) { duration = 1000 }
if (offset == null) { offset = 0 }
let targetOffsetTop = getElementOffset(targetElement).top
let containerOffsetTop = getElementOffset(containerElement).top
let scrollTarget = targetOffsetTop + ( containerElement.scrollTop - containerOffsetTop)
scrollTarget += offset
scroll(containerElement, scrollTarget, duration)
}
export const scrollWindowToElement = function(targetElement, duration, offset) {
if (duration == null) { duration = 1000 }
if (offset == null) { offset = 0 }
let scrollTarget = getElementOffset(targetElement).top
scrollTarget += offset
scrollWindow(scrollTarget, duration)
}
function scroll(containerElement, scrollTarget, duration) {
let scrollStep = scrollTarget / (duration / 15)
let interval = setInterval(() => {
if ( containerElement.scrollTop < scrollTarget ) {
containerElement.scrollTop += scrollStep
} else {
clearInterval(interval)
}
},15)
}
function scrollWindow(scrollTarget, duration) {
let scrollStep = scrollTarget / (duration / 15)
let interval = setInterval(() => {
if ( window.scrollY < scrollTarget ) {
window.scrollBy( 0, scrollStep )
} else {
clearInterval(interval)
}
},15)
}
function getElementOffset(element) {
let de = document.documentElement
let box = element.getBoundingClientRect()
let top = box.top + window.pageYOffset - de.clientTop
let left = box.left + window.pageXOffset - de.clientLeft
return { top: top, left: left }
}
Updated answer as of 2019:
$('body').animate({
scrollTop: $('#subject').offset().top - $('body').offset().top + $('body').scrollTop()
}, 'fast');
ONELINER
subject.onclick = e=> window.scroll({ top: submit.offsetTop, behavior: 'smooth'});
subject.onclick = e=> window.scroll({top: submit.offsetTop, behavior: 'smooth'});
.box,.foot{display: flex;background:#fdf;padding:500px 0} .foot{padding:250px}
<input type="text" class="textfield" value="click here" id="subject" name="subject">
<div class="box">
Some content
<textarea></textarea>
</div>
<input type="submit" class="submit" id="submit" name="submit" value="Ok, Done.">
<div class="foot">Some footer</div>
For what it's worth, this is how I managed to achieve such behavior for a general element which can be inside a DIV with scrolling. In our case we don't scroll the full body, but just particular elements with overflow: auto; within a larger layout.
It creates a fake input of the height of the target element, and then puts a focus to it, and the browser will take care about the rest no matter how deep within the scrollable hierarchy you are. Works like a charm.
var $scrollTo = $('#someId'),
inputElem = $('<input type="text"></input>');
$scrollTo.prepend(inputElem);
inputElem.css({
position: 'absolute',
width: '1px',
height: $scrollTo.height()
});
inputElem.focus();
inputElem.remove();
This worked for me:
var targetOffset = $('#elementToScrollTo').offset().top;
$('#DivParent').animate({scrollTop: targetOffset}, 2500);
When i click a link and try to scroll to a particular div with slow animation the whole page get scrolled instead of that particular div.
I am sharing the link to the plnkr below open it in full screen mode.
http://plnkr.co/edit/5ZlY7ivJ2xwckVeyIRzO?p=preview
for full screen loading
http://run.plnkr.co/HV426GUKePHeJPfS/
The problem is that when the content present in the right hand side panel is clicked (only recommendation and cme & Attended is to cliked) the middle-panel should be scrolled to show that particular div on the top.
Instead what's happening is the whole page is getting scrolled thus making the UI not much of use.
I have tried using the following two javascript code for showing some animation and scrolling the middle_profile div or mm div but none of them is working.
for scrolling middle_profile div
$("#bb").click(function() {
$('.middle_profile').animate({
scrollTop: $("#recommendationDiv").position().top
}, 'slow');
});
$("#bb1").click(function() {
$('.middle_profile').animate({
scrollTop: $("#CMEDiv").offset().top
}, 'slow');
});
for scrolling mm div
var scrolled = 0;
$("#bb").on("click", function() {
scrolled = scrolled - 300;
$(".mm").animate({
scrollTop: scrolled
}, 50);
});
Is there another way of doing it through jquery or some other library is to be included for smooth scrolling the page?
You just need to put inside the $(document).ready() your code, and set in your css the position: relative; top:0; to your div who will be focus.
$(document).ready(function(){
$("#bb").click(function() {
$('html,body').animate({
scrollTop: $("#recommendationDiv").offset().top
}, 'slow');
});
$("#bb1").click(function() {
$('html,body').animate({
scrollTop: $("#CMEDiv").offset().top
}, 'slow');
});
// var scrolled = 0;
// $("#bb").on("click" ,function(){
// scrolled=scrolled-300;
// $(".mm").animate({
// scrollTop: scrolled
// },50);
// });
})
I'm using the following script to perform the action described in my title.
<script type="text/javascript">
var jump=function(e)
{
if (e){
e.preventDefault();
var target = $(this).attr("href");
}else{
var target = location.hash;
}
$('html,body').animate(
{
scrollTop: $(target).offset().top
},1000,function()
{
location.hash = target;
});
}
$('html, body').hide();
$(document).ready(function()
{
$('a[href^=#]').bind("click", jump);
if (location.hash){
setTimeout(function(){
$('html, body').scrollTop(0).show();
jump();
}, 0);
}else{
$('html, body').show();
}
});
</script>
It works perfectly fine. However I have a fixed header which covers up the div once it's scrolled to. I'd like to minus 80px from the desired scroll target. How can I modify the code to do this?
Here's a live version.
robertkoh.net/Electrotemp/index.html
Click on 'ducted vacuum systems'. It takes you to the products and services page and scrolls to the appropriate section. As you can see the fixed header covers part of it.
Solution 1: Subtract 80 pixels and do not re-set location.hash
You only have to change this block:
$('html,body').animate({
scrollTop: $(target).offset().top
}, 1000, function() {
location.hash = target;
});
Into the following code:
$('html,body').animate({
scrollTop: $(target).offset().top - 80
}, 1000);
The added - 80 will subtract those 80 pixels, so the scrolling will stop earlier.
Removing location.hash = target; (that was called after the scroll animation was finished) fixes the problem of jumping back to the old position. This code was re-setting the hash tag which caused the browser to scroll back again. But be aware that clicking site internal hash links would not update the hash in the URL bar any more.
Solution 2: Move your page contents into a separate scrollable <div>
Create a new <div id="container"> that starts after <!--end slideMenu--> and ends before </body>.
Change the line $('html,body').animate({ into $('#container').animate({.
Remove margin-top: 70px; from .titlebar.
Add this CSS for the #container element:
#container {
position: fixed;
top: 70px;
bottom: 0;
left: 0;
overflow: auto; /* enable scrolling */
}
Doing it this way has some advantages:
You do not have to add - 80.
You do not have to remove location.hash = target;.
A browser without JavaScript enabled jumps to the right position.
I've got a scroll to top button I implemented via code that I got from one of the numerous examples out there. It works great. I changed the timing function for its appearance so that instead of appearing after 100 pixels it appears after 1340. I did this because there's some boxes on the right and I don't want the button to appear until they've been scrolled by and empty space thus appears for the button to fade in. The timing looked perfect -- the button appeared after what I figured was 1340 pixels from the top of the page.
However, I noticed that on a different (larger) screen the button didn't appear at the right time, but later. What I realized (if I gather correctly) was that the 1340 specification wasn't an absolute number of pixels from the top of the page, but was how many pixels had been scrolled through from the bottom of the browser window. For example, if I re-size the height of my browser window from, say, 1000 pixels to 400 pixels and reload the page, the button will appear 600 pixels too soon.
So my question is, is there a way to change my code so that the button appears only once a certain part of the page, measured from the top of the window, appears on screen?
Here's the javascript I'm currently using:
<script type="text/javascript">
$(document).ready(function () {
$(window).scroll(function () {
if ($(this).scrollTop() > 1340) {
$('#scrollup').fadeIn();
} else {
$('#scrollup').fadeOut();
}
});
$('#scrollup').click(function () {
$("html, body").animate({ scrollTop: 0 }, 500);
return false;
});
});
</script>
Thanks for any help.
Try this one--
<script type="text/javascript">
$(document).ready(function () {
ToggleScrollUp();
$(window).scroll(function () {
ToggleScrollUp();
});
$('#scrollup').click(function () {
$("html, body").animate({ scrollTop: 0 }, 500);
return false;
});
});
function ToggleScrollUp() {
if ($(".yourbox").offset().top < $(window).scrollTop() + $(window).height()) {
$('#scrollup').fadeIn();
} else {
$('#scrollup').fadeOut();
}
}
</script>
Check out this fiddle: http://jsfiddle.net/ro39dkaL/2/
Instead of using 1340 calculate the position of the bottom of the boxes instead, you can calculate the position on the fly so it's always accurate to the situation:
$(document).ready(function () {
var elem = $('#weblinks');
var bottom = $(elem).position().top+$(elem).outerHeight(true)
$(window).scroll(function () {
if ($(this).scrollTop() > bottom) {
$('#scrollup').fadeIn();
} else {
$('#scrollup').fadeOut();
}
});
$('#scrollup').click(function () {
$("html, body").animate({ scrollTop: 0 }, 500);
return false;
});
});
the 1340 specified is hard coded which wont be accurate in all cases.
A better solution is to find the height of the element w.r.t the browser window.
the jquery .offset() can be used.
var offset = $("#child").offset();
var fromTop = offset.top - $(window).scrollTop();
I made this fiddle and I use another way: as you can see, I placed a div with id scroll_toggle. When the user reaches this div (obviously you can remove the text, this is just a demonstration).
This is the fiddle: http://jsfiddle.net/afilini/7633pr0r/
I have this input element:
<input type="text" class="textfield" value="" id="subject" name="subject">
Then I have some other elements, like other tag's & <textarea> tag's, etc...
When the user clicks on the <input id="#subject">, the page should scroll to the page's last element, and it should do so with a nice animation (It should be a scroll to bottom and not to top).
The last item of the page is a submit button with #submit:
<input type="submit" class="submit" id="submit" name="submit" value="Ok, Done.">
The animation should not be too fast and should be fluid.
I am running the latest jQuery version. I prefer to not install any plugin but to use the default jQuery features to achieve this.
Assuming you have a button with the id button, try this example:
$("#button").click(function() {
$([document.documentElement, document.body]).animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 2000);
});
I got the code from the article Smoothly scroll to an element without a jQuery plugin. And I have tested it on the example below.
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script>
$(document).ready(function (){
$("#click").click(function (){
$('html, body').animate({
scrollTop: $("#div1").offset().top
}, 2000);
});
});
</script>
<div id="div1" style="height: 1000px; width 100px">
Test
</div>
<br/>
<div id="div2" style="height: 1000px; width 100px">
Test 2
</div>
<button id="click">Click me</button>
</html>
jQuery .scrollTo(): View - Demo, API, Source
I wrote this lightweight plugin to make page/element scrolling much easier. It's flexible where you could pass in a target element or specified value. Perhaps this could be part of jQuery's next official release, what do you think?
Examples Usage:
$('body').scrollTo('#target'); // Scroll screen to target element
$('body').scrollTo(500); // Scroll screen 500 pixels down
$('#scrollable').scrollTo(100); // Scroll individual element 100 pixels down
Options:
scrollTarget: A element, string, or number which indicates desired scroll position.
offsetTop: A number that defines additional spacing above scroll target.
duration: A string or number determining how long the animation will run.
easing: A string indicating which easing function to use for the transition.
complete: A function to call once the animation is complete.
If you are not much interested in the smooth scroll effect and just interested in scrolling to a particular element, you don't require some jQuery function for this. Javascript has got your case covered:
https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView
So all you need to do is: $("selector").get(0).scrollIntoView();
.get(0) is used because we want to retrieve the JavaScript's DOM element and not the JQuery's DOM element.
UPDATE
now is possible to scroll with animation, passing scroll options (see MDN). You can even control the block position. It seems to have large support, except for Safari
$("selector").get(0).scrollIntoView({behavior: 'smooth'});
This is achievable without jQuery:
document.getElementById("element-id").scrollIntoView();
Using this simple script
if($(window.location.hash).length > 0){
$('html, body').animate({ scrollTop: $(window.location.hash).offset().top}, 1000);
}
Would make in sort that if a hash tag is found in the url, the scrollTo animate to the ID. If not hash tag found, then ignore the script.
jQuery(document).ready(function($) {
$('a[href^="#"]').bind('click.smoothscroll',function (e) {
e.preventDefault();
var target = this.hash,
$target = $(target);
$('html, body').stop().animate( {
'scrollTop': $target.offset().top-40
}, 900, 'swing', function () {
window.location.hash = target;
} );
} );
} );
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul role="tablist">
<li class="active" id="p1">Section 1</li>
<li id="p2">Section 2</li>
<li id="p3">Section 3</li>
</ul>
<div id="pane1"></div>
<div id="pane2"></div>
<div id="pane3"></div>
This is the way I do it.
document.querySelector('scrollHere').scrollIntoView({ behavior: 'smooth' })
Works in any browser.
It can easily be wrapped into a function
function scrollTo(selector) {
document.querySelector(selector).scrollIntoView({ behavior: 'smooth' })
}
Here is a working example
$(".btn").click(function() {
document.getElementById("scrollHere").scrollIntoView( {behavior: "smooth" })
})
.btn {margin-bottom: 500px;}
.middle {display: block; margin-bottom: 500px; color: red;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="btn">Scroll down</button>
<h1 class="middle">You see?</h1>
<div id="scrollHere">Arrived at your destination</div>

The solution by Steve and Peter works very well.
But in some cases, you may have to convert the value to an integer. Strangely, the returned value from $("...").offset().top is sometimes in float.
Use: parseInt($("....").offset().top)
For example:
$("#button").click(function() {
$('html, body').animate({
scrollTop: parseInt($("#elementtoScrollToID").offset().top)
}, 2000);
});
A compact version of "animate" solution.
$.fn.scrollTo = function (speed) {
if (typeof(speed) === 'undefined')
speed = 1000;
$('html, body').animate({
scrollTop: parseInt($(this).offset().top)
}, speed);
};
Basic usage: $('#your_element').scrollTo();
With this solution you do not need any plugin and there's no setup required besides placing the script before your closing </body> tag.
$("a[href^='#']").on("click", function(e) {
$("html, body").animate({
scrollTop: $($(this).attr("href")).offset().top
}, 1000);
return false;
});
if ($(window.location.hash).length > 1) {
$("html, body").animate({
scrollTop: $(window.location.hash).offset().top
}, 1000);
}
On load, if there is a hash in the address, we scroll to it.
And - whenever you click an a link with an href hash e.g. #top, we scroll to it.
##Edit 2020
If you want a pure JavaScript solution: you could perhaps instead use something like:
var _scrollToElement = function (selector) {
try {
document.querySelector(selector).scrollIntoView({ behavior: 'smooth' });
} catch (e) {
console.warn(e);
}
}
var _scrollToHashesInHrefs = function () {
document.querySelectorAll("a[href^='#']").forEach(function (el) {
el.addEventListener('click', function (e) {
_scrollToElement(el.getAttribute('href'));
return false;
})
})
if (window.location.hash) {
_scrollToElement(window.location.hash);
}
}
_scrollToHashesInHrefs();
If you are only handling scrolling to an input element, you can use focus(). For example, if you wanted to scroll to the first visible input:
$(':input:visible').first().focus();
Or the first visible input in an container with class .error:
$('.error :input:visible').first().focus();
Thanks to Tricia Ball for pointing this out!
Easy way to achieve the scroll of page to target div id
var targetOffset = $('#divID').offset().top;
$('html, body').animate({scrollTop: targetOffset}, 1000);
If you want to scroll within an overflow container (instead of $('html, body') answered above), working also with absolute positioning, this is the way to do :
var elem = $('#myElement'),
container = $('#myScrollableContainer'),
pos = elem.position().top + container.scrollTop() - container.position().top;
container.animate({
scrollTop: pos
}
After finding the way to get my code work, I think I should make thing a bit clear:
For using:
$('html, body').animate({
scrollTop: $("#div1").offset().top
}, 2000);
you need to be on top of the page since $("#div1").offset().top will return different numbers for different positions you scroll to. If you already scrolled out of the top, you need to specify the exact pageY value (see pageY definition here: https://javascript.info/coordinates).
So now, the problem is to calculate the pageY value of one element. Below is an example in case the scroll container is the body:
function getPageY(id) {
let elem = document.getElementById(id);
let box = elem.getBoundingClientRect();
var body = document.getElementsByTagName("BODY")[0];
return box.top + body.scrollTop; // for window scroll: box.top + window.scrollY;
}
The above function returns the same number even if you scrolled somewhere. Now, to scroll back to that element:
$("html, body").animate({ scrollTop: getPageY('div1') }, "slow");
Animations:
// slide to top of the page
$('.up').click(function () {
$("html, body").animate({
scrollTop: 0
}, 600);
return false;
});
// slide page to anchor
$('.menutop b').click(function(){
//event.preventDefault();
$('html, body').animate({
scrollTop: $( $(this).attr('href') ).offset().top
}, 600);
return false;
});
// Scroll to class, div
$("#button").click(function() {
$('html, body').animate({
scrollTop: $("#target-element").offset().top
}, 1000);
});
// div background animate
$(window).scroll(function () {
var x = $(this).scrollTop();
// freezze div background
$('.banner0').css('background-position', '0px ' + x +'px');
// from left to right
$('.banner0').css('background-position', x+'px ' +'0px');
// from right to left
$('.banner0').css('background-position', -x+'px ' +'0px');
// from bottom to top
$('#skills').css('background-position', '0px ' + -x + 'px');
// move background from top to bottom
$('.skills1').css('background-position', '0% ' + parseInt(-x / 1) + 'px' + ', 0% ' + parseInt(-x / 1) + 'px, center top');
// Show hide mtop menu
if ( x > 100 ) {
$( ".menu" ).addClass( 'menushow' );
$( ".menu" ).fadeIn("slow");
$( ".menu" ).animate({opacity: 0.75}, 500);
} else {
$( ".menu" ).removeClass( 'menushow' );
$( ".menu" ).animate({opacity: 1}, 500);
}
});
// progres bar animation simple
$('.bar1').each(function(i) {
var width = $(this).data('width');
$(this).animate({'width' : width + '%' }, 900, function(){
// Animation complete
});
});
In most cases, it would be best to use a plugin. Seriously. I'm going to tout mine here. Of course there are others, too. But please check if they really avoid the pitfalls for which you'd want a plugin in the first place - not all of them do.
I have written about the reasons for using a plugin elsewhere. In a nutshell, the one liner underpinning most answers here
$('html, body').animate( { scrollTop: $target.offset().top }, duration );
is bad UX.
The animation doesn't respond to user actions. It carries on even if the user clicks, taps, or tries to scroll.
If the starting point of the animation is close to the target element, the animation is painfully slow.
If the target element is placed near the bottom of the page, it can't be scrolled to the top of the window. The scroll animation stops abruptly then, in mid motion.
To handle these issues (and a bunch of others), you can use a plugin of mine, jQuery.scrollable. The call then becomes
$( window ).scrollTo( targetPosition );
and that's it. Of course, there are more options.
With regard to the target position, $target.offset().top does the job in most cases. But please be aware that the returned value doesn't take a border on the html element into account (see this demo). If you need the target position to be accurate under any circumstances, it is better to use
targetPosition = $( window ).scrollTop() + $target[0].getBoundingClientRect().top;
That works even if a border on the html element is set.
This is my approach abstracting the ID's and href's, using a generic class selector
$(function() {
// Generic selector to be used anywhere
$(".js-scroll-to").click(function(e) {
// Get the href dynamically
var destination = $(this).attr('href');
// Prevent href=“#” link from changing the URL hash (optional)
e.preventDefault();
// Animate scroll to destination
$('html, body').animate({
scrollTop: $(destination).offset().top
}, 500);
});
});
<!-- example of a fixed nav menu -->
<ul class="nav">
<li>
Item 1
</li>
<li>
Item 2
</li>
<li>
Item 3
</li>
</ul>
Very simple and easy to use custom jQuery plugin. Just add the attribute scroll= to your clickable element and set its value to the selector you want to scroll to.
Like so: <a scroll="#product">Click me</a>. It can be used on any element.
(function($){
$.fn.animateScroll = function(){
console.log($('[scroll]'));
$('[scroll]').click(function(){
selector = $($(this).attr('scroll'));
console.log(selector);
console.log(selector.offset().top);
$('html body').animate(
{scrollTop: (selector.offset().top)}, //- $(window).scrollTop()
1000
);
});
}
})(jQuery);
// RUN
jQuery(document).ready(function($) {
$().animateScroll();
});
// IN HTML EXAMPLE
// RUN ONCLICK ON OBJECT WITH ATTRIBUTE SCROLL=".SELECTOR"
// <a scroll="#product">Click To Scroll</a>
$('html, body').animate(...) does not work for me in the iPhone, Android, Chrome, or Safari browsers.
I had to target the root content element of the page.
$('#cotnent').animate(...)
Here is what I have ended up with:
if (navigator.userAgent.match(/(iPod|iPhone|iPad|Android)/)) {
$('#content').animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 'slow');
}
else{
$('html, body').animate({
scrollTop: $("#elementtoScrollToID").offset().top
}, 'slow');
}
All body content wired up with a #content div
<html>
....
<body>
<div id="content">
...
</div>
</body>
</html>
$('html, body').animate({scrollTop:
Math.min(
$(to).offset().top-margintop, //margintop is the margin above the target
$('body')[0].scrollHeight-$('body').height()) //if the target is at the bottom
}, 2000);
To show the full element (if it's possible with the current window size):
var element = $("#some_element");
var elementHeight = element.height();
var windowHeight = $(window).height();
var offset = Math.min(elementHeight, windowHeight) + element.offset().top;
$('html, body').animate({ scrollTop: offset }, 500);
var scrollTo = function($parent, $element) {
var topDiff = $element.position().top - $parent.position().top;
$parent.animate({
scrollTop : topDiff
}, 100);
};
This is Atharva's answer from: https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView.
Just wanted to add if your document is in an iframe, you can choose an element in the parent frame to scroll into view:
$('#element-in-parent-frame', window.parent.document).get(0).scrollIntoView();
I wrote a general purpose function that scrolls to either a jQuery object, a CSS selector, or a numeric value.
Example usage:
// scroll to "#target-element":
$.scrollTo("#target-element");
// scroll to 80 pixels above first element with class ".invalid":
$.scrollTo(".invalid", -80);
// scroll a container with id "#my-container" to 300 pixels from its top:
$.scrollTo(300, 0, "slow", "#my-container");
The function's code:
/**
* Scrolls the container to the target position minus the offset
*
* #param target - the destination to scroll to, can be a jQuery object
* jQuery selector, or numeric position
* #param offset - the offset in pixels from the target position, e.g.
* pass -80 to scroll to 80 pixels above the target
* #param speed - the scroll speed in milliseconds, or one of the
* strings "fast" or "slow". default: 500
* #param container - a jQuery object or selector for the container to
* be scrolled. default: "html, body"
*/
jQuery.scrollTo = function (target, offset, speed, container) {
if (isNaN(target)) {
if (!(target instanceof jQuery))
target = $(target);
target = parseInt(target.offset().top);
}
container = container || "html, body";
if (!(container instanceof jQuery))
container = $(container);
speed = speed || 500;
offset = offset || 0;
container.animate({
scrollTop: target + offset
}, speed);
};
When the user clicks on that input with #subject, the page should
scroll to the last element of the page with a nice animation. It
should be a scroll to bottom and not to top.
The last item of the page is a submit button with #submit
$('#subject').click(function()
{
$('#submit').focus();
$('#subject').focus();
});
This will first scroll down to #submit then restore the cursor back to the input that was clicked, which mimics a scroll down, and works on most browsers. It also doesn't require jQuery as it can be written in pure JavaScript.
Can this fashion of using focus function mimic animation in a better way, through chaining focus calls. I haven't tested this theory, but it would look something like this:
<style>
#F > *
{
width: 100%;
}
</style>
<form id="F" >
<div id="child_1"> .. </div>
<div id="child_2"> .. </div>
..
<div id="child_K"> .. </div>
</form>
<script>
$('#child_N').click(function()
{
$('#child_N').focus();
$('#child_N+1').focus();
..
$('#child_K').focus();
$('#child_N').focus();
});
</script>
I set up a module scroll-element npm install scroll-element. It works like this:
import { scrollToElement, scrollWindowToElement } from 'scroll-element'
/* scroll the window to your target element, duration and offset optional */
let targetElement = document.getElementById('my-item')
scrollWindowToElement(targetElement)
/* scroll the overflow container element to your target element, duration and offset optional */
let containerElement = document.getElementById('my-container')
let targetElement = document.getElementById('my-item')
scrollToElement(containerElement, targetElement)
Written with help from the following SO posts:
offset-top-of-an-element-without-jquery
scrolltop-animation-without-jquery
Here is the code:
export const scrollToElement = function(containerElement, targetElement, duration, offset) {
if (duration == null) { duration = 1000 }
if (offset == null) { offset = 0 }
let targetOffsetTop = getElementOffset(targetElement).top
let containerOffsetTop = getElementOffset(containerElement).top
let scrollTarget = targetOffsetTop + ( containerElement.scrollTop - containerOffsetTop)
scrollTarget += offset
scroll(containerElement, scrollTarget, duration)
}
export const scrollWindowToElement = function(targetElement, duration, offset) {
if (duration == null) { duration = 1000 }
if (offset == null) { offset = 0 }
let scrollTarget = getElementOffset(targetElement).top
scrollTarget += offset
scrollWindow(scrollTarget, duration)
}
function scroll(containerElement, scrollTarget, duration) {
let scrollStep = scrollTarget / (duration / 15)
let interval = setInterval(() => {
if ( containerElement.scrollTop < scrollTarget ) {
containerElement.scrollTop += scrollStep
} else {
clearInterval(interval)
}
},15)
}
function scrollWindow(scrollTarget, duration) {
let scrollStep = scrollTarget / (duration / 15)
let interval = setInterval(() => {
if ( window.scrollY < scrollTarget ) {
window.scrollBy( 0, scrollStep )
} else {
clearInterval(interval)
}
},15)
}
function getElementOffset(element) {
let de = document.documentElement
let box = element.getBoundingClientRect()
let top = box.top + window.pageYOffset - de.clientTop
let left = box.left + window.pageXOffset - de.clientLeft
return { top: top, left: left }
}
Updated answer as of 2019:
$('body').animate({
scrollTop: $('#subject').offset().top - $('body').offset().top + $('body').scrollTop()
}, 'fast');
ONELINER
subject.onclick = e=> window.scroll({ top: submit.offsetTop, behavior: 'smooth'});
subject.onclick = e=> window.scroll({top: submit.offsetTop, behavior: 'smooth'});
.box,.foot{display: flex;background:#fdf;padding:500px 0} .foot{padding:250px}
<input type="text" class="textfield" value="click here" id="subject" name="subject">
<div class="box">
Some content
<textarea></textarea>
</div>
<input type="submit" class="submit" id="submit" name="submit" value="Ok, Done.">
<div class="foot">Some footer</div>
For what it's worth, this is how I managed to achieve such behavior for a general element which can be inside a DIV with scrolling. In our case we don't scroll the full body, but just particular elements with overflow: auto; within a larger layout.
It creates a fake input of the height of the target element, and then puts a focus to it, and the browser will take care about the rest no matter how deep within the scrollable hierarchy you are. Works like a charm.
var $scrollTo = $('#someId'),
inputElem = $('<input type="text"></input>');
$scrollTo.prepend(inputElem);
inputElem.css({
position: 'absolute',
width: '1px',
height: $scrollTo.height()
});
inputElem.focus();
inputElem.remove();
This worked for me:
var targetOffset = $('#elementToScrollTo').offset().top;
$('#DivParent').animate({scrollTop: targetOffset}, 2500);
