Hi,
thx for this script! It works perfectly with IE 8 and Opera 10, but not with Firefox 3.5. It returns a height of about 30 pixels, even though the document’s height is 1000+ pixel.
Any idea?

Thank you for posting this. Surely solves a lot of my presentation issues being able to resize the containers dynamically based on content.

You can pass as many values as you want into Math.max(). Try this:

var db = document.body;
var dde = document.documentElement;
 
var docHeight = Math.max(db.scrollHeight, dde.scrollHeight, db.offsetHeight, dde.offsetHeight, db.clientHeight, dde.clientHeight)

Great piece of code James – nice,simple and comprehensive. Thanks and loving your work!

Any reason you didn’t use ‘document.height’ tho?

Thanks, James. That’s a wonderfully helpful little snippet (especially in jQuery). It just solved an IE6 jqModal overlay nightmare for me.

Excellent !!! I call the function at the end of my html script and it works just fine. I have successfully tested also on Netscape 9 (Mozilla 5.0), even if I know it is at the end of his life.

Any ideas how to get this into the css without flickering… (I believe the height is only known after the page has loaded)..

Nice code though, compliments, greets, Dylan

Actually in jQuery it’s a bit easier because it does most of the work for us:

$.getDocHeight = function(){
    return Math.max(
        $(document).height(),
        $(window).height(),
        /* For opera: */
        document.documentElement.clientHeight
    );
};

And for us jQuery junkies:

$.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() );
