Consider I have a list of questions. When I click on the first question, it should automatically take me to the bottom of the page.
For a matter of fact, I do know
If you want to scroll entire page to the bottom:
var scrollingElement = (document.scrollingElement || document.body);
scrollingElement.scrollTop = scrollingElement.scrollHeight;
See the sample on JSFiddle
If you want to scroll an element to the bottom:
function gotoBottom(id){
var element = document.getElementById(id);
element.scrollTop = element.scrollHeight - element.clientHeight;
}
And that's how it works:
Ref: scrollTop, scrollHeight, clientHeight
UPDATE: Latest versions of Chrome (61+) and Firefox does not support scrolling of body, see: https://dev.opera.com/articles/fixing-the-scrolltop-bug/
