I have a few links on my sidebar on my website. The links have the class sidebarelement. Everytime I click one of them I have to click twice to scroll to my content. After the first time nothing happens. I use jQuery.
$(".sidebarelement").on("click", function () {
var offset = $(':target').offset();
if (offset) {
var scrollto = offset.top - 158; // minus fixed header height
$('html, body').animate({scrollTop: scrollto});
}
});
How can I fix this?
For everyone else who had this problem I got a solution.
The idea is to get the href attribute from the link which has been clicked and animate (scroll) to that place. Also note that e.preventDefault() prevents the link to jump to his place.
Here is my code snippet.
$(document).ready(function () {
$('.sidebarelement').on("click", function () {
var href = $(this).attr('href');
$('html, body').animate({
scrollTop: $(href).offset().top - document.getElementById('navDiv').clientHeight // minus fixed header height
}, 'slow');
e.preventDefault();
});
});

I am trying to create smooth scrolling to IDs. When I click on a link its ID should be scroll to top (at a certain point of top. Ex: 200px from top) of the page.
I tried it something like this:
var $root = $('html, body');
$('a[href*=#]').click(function() {
var href = $.attr(this, 'href');
$root.animate({
scrollTop: (($(href).offset().top >= 200 ) ? $(href).offset().top : 200)
}, 500, function () {
window.location.hash = href;
});
return false;
});
But it doesn't work and its always scrolling to top of the page.
Hope somebody may help me out.
I guess, the problem is your href, the target will presumably not be found. Maybe you'd be better off to store the element to scroll to in a data attribute, like so:
$('a[href*=#]').click(function(evt) {
evt.preventDefault();
var target = $(this).data('target');
$('html, body').animate({
scrollTop: $(target).offset().top
}, 2000);
});
With an anchor tag like so:
Brilliant rainbow colors
Obviously, the element with the ID somewhere_over_the_rainbow must exist somewhere in your DOM.
This should do the job correctly :
$('a[href*=#]').click(function() {
var href = $.attr(this, 'href');
var top = $(href).offset().top;
$('body').animate(
{
scrollTop: top - 200
},
500
);
return false;
});
Obviously, the item with the id equal to the hash of the anchor must exist.
I need to create smooth scroll to IDs using jQuery.
Here is my code:
var $root = $('html, body');
$('a[href*=#]').click(function() {
var href = $.attr(this, 'href');
$root.animate({
scrollTop: $(href).offset().top
}, 500, function () {
window.location.hash = href;
});
return false;
});
Its working fine for me. But one thing, I need to stop scrolling at a certain point of the top of the page. For example 200px from the top.
At this stage its always scrolling to top of the page.
Can anybody tell me how to modify this code?
Thank you.
by adding this:
(($(href).offset().top >= 200 ) ? $(href).offset().top : 200)
It checks how far the element is away from the top, if its more than 200px it will scroll to it else it will scroll to 200px from the top
here is the new code:
var $root = $('html, body');
$('a[href*=#]').click(function() {
var href = $.attr(this, 'href');
$root.animate({
scrollTop: (($(href).offset().top >= 200 ) ? $(href).offset().top : 200)
}, 500, function () {
window.location.hash = href;
});
return false;
});
If i understood you correctly, you have something like header with height for example 200px and position:fixed to top. And your current script is scrolling too high, hiding hash title under the header.
So if this correct you just need to subtract header height from $(href).offset().top (e.g. scrollTop: $(href).offset().top-200)
jsFiddle
Change this line scrollTop: $(href).offset().top to scrollTop: $("body").offset().top + 200
This will take the really top position (0) and then you can manipulate your scrolling for position you need
I'm looking for a code that scrolls up to the top of the currently active panel heading of my bootstrap 3 html/css accordion. The closest solution I've found on stackoverflow is the snippet of js below.
This snippet works fairly well, but when a panel heading gets clicked the page scrolls such that the very top of the panel content is flush with the top of the screen. Is there a way to modify this so that the scrolling effect will result in the panel "heading" (as opposed to the top of panel content area) being visible at the top of the screen?
$(function () {
$('#accordion').on('shown.bs.collapse', function (e) {
var offset = $('.panel.panel-default > .panel-collapse.in').offset();
if(offset)$('html,body').scrollTop(offset.top); }); });
Let me know if I should be sharing the bootstrap accordion html as well.
I used this and it works fine you can adjust the -20 after the .offset().top if you need to tweak it up or down a little.
$(function () {
$('#accordion').on('shown.bs.collapse', function (e) {
var offset = $('.panel.panel-default > .panel-collapse.in').offset();
if(offset) {
$('html,body').animate({
scrollTop: $('.panel-title a').offset().top -20
}, 500);
}
});
});
This is to target the specific .panel-heading clicked as per James Wilson's comment on the accepted answer.
$(function () {
$('#accordion').on('shown.bs.collapse', function (e) {
var offset = $(this).find('.collapse.in').prev('.panel-heading');
if(offset) {
$('html,body').animate({
scrollTop: $(offset).offset().top -20
}, 500);
}
});
});
All I changed from gigelsmith's accepted answer is 'var offset' and the scrollTop's target.
I couldn't get the answer above to work, perhaps I'm missing something but I can't see how the scrollTop line above relates to the currently opened accordion item so used the following code instead. Hope it helps someone else:
$(function () {
$('#accordion').on('shown.bs.collapse', function (e) {
var offset = $('.panel.panel-default > .panel-collapse.in').offset();
if(offset) {
$('html,body').animate({
scrollTop: $('.panel-collapse.in').siblings('.panel-heading').offset().top
}, 500);
}
});
});
Always animate looks a bit too much so this is my version to only do the job when heading is over the visible part.
(note that I use a data-accordion-focus to apply the fix)
$('[data-accordion-focus]').on('shown.bs.collapse', function (e) {
var headingTop = $(e.target).prev('.panel-heading').offset().top - 5;
var visibleTop = $(window).scrollTop();
if (headingTop < visibleTop) {
$('html,body').animate({
scrollTop: headingTop
}, 500);
}
});
By using .panel-default as selector of .on(), you can scroll to the active panel.
$('#accordion').on('shown.bs.collapse', '.panel-default', function (e) {
$('html,body').animate({
scrollTop: $(this).offset().top
}, 500);
});
In Demo 01 You can see the Div is Scrolling top of the page with increase height. And I need the same animation with click Buttons, like in Demo 02.
$('.work-showcase').click(function(){
$('.work-showcase').animate({height:'135px'}, 500);
$(this).animate({height:'400px'}, 500,function() {
$("html, body").animate({ scrollTop: $(this).offset().top });
});
});
Not sure if I understand what you want, but see if this Javascript works for you:
var map = {
"slice1": "#post1",
"slice2": "#post2",
"slice3": "#post3",
}
$('.clickable').click(function(){
var postId = map[$(this).attr('id')];
$('.post').animate({height:'50px'}, 500);
$(postId).animate({height:'400px'}, 500,function() {
$("html, body").animate({ scrollTop: $(postId).offset().top });
});
});
See demo at http://jsfiddle.net/xCKPW/1/.
What I think you want to do is have the animation and size change that you currently have get triggered when a button is clicked.
I also suspect you want the action to occur when the image is clicked.
In this case, move the animations into a separate function, and call that function onclick.
Here's your jsfiddle updated with buttons.
http://jsfiddle.net/Jq4Vw/132/
$('.work-showcase, button').click(function(){
moveAndResize($(this).index());
});
function moveAndResize(index){
var item = $('.work-showcase:eq('+index+')');
$('.work-showcase').animate({height:'135px'}, 500);
$(item).animate({height:'400px'}, 500,function() {
$("html, body").animate({ scrollTop: $(item).offset().top });
});
}
This works as long as the indexes are the same. If you want the index of the buttons to be different, add an id tag or something else that you can then pass to the moveAndResize which maps to the index of the item you want to change.
I have a project where the logo will load in the center of the page when the user comes to the website. Then, if the user scrolls down, the logo will scroll to the top and the content will follow, but, the logo will become fixed on top once it reaches top of the window. So, what I want to do is, stop the content from going to the top (because that content goes behind the logo), e.g. #Furniture is the div, that goes to top when an anchor tag with href"#Furniture" is clicked. I want to stop the div containing #Furniture at 150px (logo's height) from top of the browser. Is that possible?
Following is the code that I have used for smooth scrolling of any div to the top:
$(window).load(function () {
var $root = $('html, body');
$('a').click(function () {
var href = $.attr(this, 'href');
$root.animate({
scrollTop: $(href).offset().top
}, 500, function () {
window.location.hash = href;
});
return false;
});
});
Fiddle
Use like this:
var top_val = $(href).offset().top; // or anything your code for getting top value
$root.animate({
top: "+top_val+"
}, 500, function () {
window.location.hash = href;
});
