javascript - .body.scrollHeight doesn't work in Firefox

Question

.body.scrollHeight does not work in Firefox.

See: http://jsfiddle.net/gjrowe/X63KR/

What is the correct syntax to use instead?

Answer 1

This question has the same root problem as the thread at... Dynamically define iframe height based on window size (NOT CONTENT)

Understanding the issue at that thread will give the solution to this.

Basically, instead of using .body.scrollHeight, add this code...

function getDocHeight() {
    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)
    );
}
