How do I get the scroll position of a document?

Question

How to get the scroll position value of a document?

Answer 1

Something like this should solve your problem:

$.getDocHeight = function(){
     var D = document;
     return Math.max(Math.max(D.body.scrollHeight,    D.documentElement.scrollHeight), Math.max(D.body.offsetHeight, D.documentElement.offsetHeight), Math.max(D.body.clientHeight, D.documentElement.clientHeight));
};

alert( $.getDocHeight() );

Ps: Call that function every time you need it, the alert is for testing purposes..
