I'm looking to have the user scroll down the page and when it hits certain points 'stick' for a few moments before continuing scrolling. I have a large vertial page which has content in between large images, when the user hits these peices of content the browser should stop scrolling for a moment then continue scrolling. I'm hoping this will help highlight the content amongst all the images on the page.
I hope this is clear enough :s
cheers
You can try something like this:
$(function () {
var delay = 2000,
//Following var because http://stackoverflow.com/questions/3042651/jquery-scrolltop-not-working-in-chrome-but-working-in-firefox
$scrollEl = $.browser.mozilla ? $('html') : $('body');
selectors = ['#img1', '#img2', '#img3'];
(function scrollPage() {
var $el = $(selectors.shift());
if ($el.length === 0) return;
//animate
$scrollEl.animate({ scrollTop: $el.offset().top }, 2000, function () {
setTimeout(scrollPage, delay);
});
})();
});

I'm using this simple code, and it's working fine.
$("#mydiv").animate({ scrollTop: $('#mydiv')[0].scrollHeight}, 20000)
What I would like is to after the bottom has been reached immediately go back to the top of the page and start scrolling down slowly again. How would one achive something like this in JQuery?
Thank you guys!
you can jump back to the top of your page using the following javascript function:
function jump(elementId){
var location = document.getElementById(elementId).offsetTop;
window.scrollTo(0, location);
}
just use the id of some element at the top of your page.
Not sure what you are trying to do and what "reload" means but here is a quick snippet to get you started:
JSnippet Demo
As you can see its configurable and easy to understand:
$(function() {
var pageScan = {
speed : 10000,
loop : true,
delayRestart : 1000,
start : function(){
pageHeight = $('body').height() - window.innerHeight;
pageScan.proc(pageHeight);
},
proc : function(to){
$("body").animate(
{scrollTop: to},
pageScan.speed,
"linear",
function(){
if (pageScan.loop) {
setTimeout(function() {
window.scrollTo(0, 0);
pageScan.start();
}, pageScan.delayRestart);
}
});
}
};
pageScan.start();
});
We could do something easier like this:
(function (){
var div = $('#myDiv'),
infiniteScroll = function () {
//---gets the bottom of the page value
var bottomHeight = div[0].scrollHeight;
var callback1 = function () {
//once it gets into this callback function
//it resets the position to zero
div.scrollTop(0);
//invokes again the function infinite scroll
infiniteScroll();
};
div.animate({scrollTop:bottomHeight},20000,callback1)
};
//starts the function for the very first time
infiniteScroll();
})();
I created a codepen so you can see it working and play with it:

I am working with a script to scroll an element on click. It's working properly, however it either scrolls all the way up, or all the way down. I'm new to jquery, and I'm wondering how to make it scroll a little at at time. For example, clicking to scroll down once will take you down a certain length, clicking again scrolls that length again. Also, sometimes it jitters and bugs out when scrolling back up. Any insight on how to fix this is appreciated as well!
Thanks.
Code below:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
<script>
$(function() {
var ele = $('#scroll');
var speed = 25, scroll = 5, scrolling;
$('#scroll-up').click(function() {
// Scroll the element up
scrolling = window.setInterval(function() {
ele.scrollTop( ele.scrollTop() - scroll );
}, speed);
});
$('#scroll-down').click(function() {
// Scroll the element down
scrolling = window.setInterval(function() {
ele.scrollTop( ele.scrollTop() + scroll );
}, speed);
});
$('#scroll-up, #scroll-down').bind({
click: function(e) {
// Prevent the default click action
e.preventDefault();
},
mouseleave: function() {
if (scrolling) {
window.clearInterval(scrolling);
scrolling = false;
}
}
});
});
</script>
You're saying you want to scroll little at a time but your code is saying scroll UNTIL mouse leaves. If you want to scroll little at a time why would you write a mouseleave which clearly stating if it's been scrolling stop now!
If you want to scroll up/down a bit on click, you should get rid of setInterval and mouseleave.
$(function() {
var ele = $('#scroll');
var speed = 25, scroll = 5;
$('#scroll-up').click(function() {
// Scroll the element up
ele.scrollTop( ele.scrollTop() - scroll );
});
$('#scroll-down').click(function() {
ele.scrollTop( ele.scrollTop() + scroll );
});
$('#scroll-up, #scroll-down').bind({
click: function(e) {
// Prevent the default click action
e.preventDefault();
}
});
});

I want to show a table of contents (for a long web document) as a fixed element on the right side of the page.
I got a 'hello world' of this going fairly easily, but I can't figure out how to keep the element from fading in and out during long scrolls.
Scroll around enough on the fiddle and you'll see what I mean.
js fiddle: http://jsfiddle.net/XGY8H/2/
$(window).scroll(function(){
var toc = $('.tableOfContents');
toc.fadeIn();
setTimeout(function(){
toc.fadeOut();
},10000);
});
Thanks!
You cas use clearTimeout to prevent the ToC from fading out.
$(function () {
var toc = $('.tableOfContents');
var fadeTimer;
toc.fadeOut();
$(window).scroll(function () {
toc.fadeIn();
if (fadeTimer) {
clearTimeout(fadeTimer);
}
fadeTimer = setTimeout(function () {
fadeTimer = 0;
toc.fadeOut();
}, 10000);
});
});

When a user clicks on the "Contact Me" button, i want the screen to slide to the #contact element, however cannot figure out how to do it. I've tried various different snippets of code and tried to tailor it to my needs, but nothing seems to work.
The site is here; http://dombracher.com/
Simply want the screen to slide to the div mentioned above, rather than quickly snap to it.
Thanks in advance.
$(document).ready(function() {
$("a[href^='#']").anchorAnimate()
});
jQuery.fn.anchorAnimate = function(settings) {
settings = jQuery.extend({
speed : 1100
}, settings);
return this.each(function(){
var caller = this
$(caller).click(function (event) {
event.preventDefault()
var locationHref = window.location.href
var elementClick = $(caller).attr("href")
var destination = $(elementClick).offset().top;
$("html:not(:animated),body:not(:animated)").animate({ scrollTop: destination}, settings.speed, function() {
window.location.hash = elementClick
});
return false;
})
})
}
You can animate window scroll by yourself
$(".menu2").click(function(){
$(document.body).animate({
"scrollTop": $("#contact").offset().top
}, 2000, "swing"); // animation time and easing
return false; // preventing default jump
});
Fiddle: http://jsfiddle.net/M8JE2/
Or use jquery plugin like http://flesler.blogspot.com/2007/10/jquerylocalscroll-10.html to make any/all local links work with animation.
Here it is , scrolls to the bottom of the page since your contact form is there:
jQuery(function () {
jQuery('#nav1 li.menu2').click(function (e) {
jQuery("html, body").stop().animate({
scrollTop: jQuery(document).height()
}, 1000);
e.preventDefault();
return false;
});
});
Please check what i did yet http://jsfiddle.net/dUVmh/1/ .
About the animation i want to achieve is that:
When you first scroll down the page then window scroll to #green DIV. After that if you again scroll down window scroll to #yellow DIV & same at the time of scrollup (fom #yellow to #green).
About the issue:
You can see the animation it's stuck on #green DIV.
$(window).scroll(function(){
if($(this).scrollTop() > 0) {
$("html, body").animate({ scrollTop: $('#green').offset().top }, 1000);
}
else if($(this).scrollTop() > 1000) {
$("html, body").animate({ scrollTop: $('#yellow').offset().top }, 1000);
}
else{
$("html, body").animate({ scrollTop: $('#red').offset().top }, 1000);
}
});
I didn't have much experience in JS.
Thanks i advance :)
This was a fun problem to work on.
This solution places the divs into an array, and remembers the array index of the element that was last scrolled to. Once a scroll event is triggered it checks to see if the new scrollTop is above or below the current divs top offset and moves to the next or previous div in the array accordingly.
This solution allows you to have many divs. I tried to remove the flickering you get when you scroll to fast, but the only way to do that I believe would be to disable the scrollbars during animation.
http://jsfiddle.net/dUVmh/35/
$(function() {
var divs = [],
body = $('body, html'),
currentDiv = 0,
timeout;
$('div').each(function() {
divs.push($(this));
});
// we only need to capture the first scroll event triggered and then
// add another listener once we have done our animation
var scrollListen = function() {
$(window).one('scroll', function() {
doScroll($(this).scrollTop());
});
};
// Without the timeout, the scroll event would be triggered again too soon
var scrollEnd = function() {
clearTimeout(timeout);
timeout = setTimeout(function() {
scrollListen();
}, 10);
};
// checks if the scroll direction was up and down and animates
// the body scrollTop to the next or previous div
var doScroll = function(scrollTop) {
var direction = scrollTop - divs[currentDiv].offset().top;
if (direction > 0 && currentDiv + 1 < divs.length) {
nextDiv = currentDiv + 1;
} else if (currentDiv - 1 > -1) {
nextDiv = currentDiv - 1;
}
if (currentDiv === nextDiv) {
scrollEnd();
}
body.animate({
scrollTop: divs[nextDiv].offset().top
}, 1000, function() {
currentDiv = nextDiv;
scrollEnd();
});
};
scrollListen();
});
Edit: Firefox scrollTop required to be changed on html and not body. Also fixed a problem with firefox calling scrollListen more than once at a time.
The problem is that the $(window).scroll(function()) gets called over and over again when scrolling through the ScrollTop animation with jQuery.
Here is a possible solution that checks if it is currently scrolling or not and only executes the ScrollTop animation once.
http://jsfiddle.net/dUVmh/29/
Side note: It might be a good idea to check which direction the user is scrolling (up or down) and depending on that scroll to the next div to the top or to the down.
You can check that be saving the last scrollTop position and comparing it with the current one.
UPDATE: Here's a solution that takes the scroll direction into account: http://jsfiddle.net/dUVmh/36/
