Scroll to an html element with a particular id in javascript or jquery
I have html elements with id's assigned. Now I want to scroll to those elements. I see jQuery h开发者_运维问答as a scrollTop which takes an integer value.. How do I easily just make a particular html element with an id scroll to the top? Ideally, with nice and smooth animation.
A quick search showed many scrolling plugins... if a plugin is needed for the above functionality, what's the most popular one? I'm also using jquery-ui.
You could use something like this to scroll to #someElement
when the page loads:
$(document).ready(function() {
$("html, body").animate({scrollTop: $("#someElement").offset().top}, 1000);
});
It simply animates the scrollTop
property of the body
element, and uses the top offset of some specific element as the position to scroll to. The animation lasts for 1000ms.
Note: it selects both html
and body
so it works across browsers. I'm not sure on the specifics, but some quick tests show that Chrome uses body
, but Firefox and IE use html
.
Here's a working example.
Consider the following snippet:
$('#myDiv').bind('click',function(){
var pos = $(this).offset().top,
scrollSpeed = 2;
for (var i = pos; i > 0; i=i-scrollSpeed) {
$(window).scrollTop(i);
}
});
It scrolling was binded to #myDiv element on click just for example. Code determines a position of #myDiv element, than calculates number of scroll steps (speed/smoothness). Than does jQuery .scrollTop() thing.
