How to get height of entire document with JavaScript?

Question

Some documents I can\'t get the height of the document (to position something absolutely at the very bottom). Additionally, a padding-bottom on seems to do nothing on these

Answer 1

You can even use this:

var B = document.body,
    H = document.documentElement,
    height

if (typeof document.height !== 'undefined') {
    height = document.height // For webkit browsers
} else {
    height = Math.max( B.scrollHeight, B.offsetHeight,H.clientHeight, H.scrollHeight, H.offsetHeight );
}

or in a more jQuery way (since as you said jQuery doesn't lie) :)

Math.max($(document).height(), $(window).height())
