Total height of the page
<p>I'm trying to get the total height of a page using JavaScript and jQuery so I can check if the page is long enough to display something, however in my testing I am unable to get the total height of a page.</p>

<p>I've looked around on the Internet but things like this don't seem to be well documented, as all I can find is <code>scrollHeight</code>, which, as I might mention, doesn't work. </p>

<p>Any way to use jQuery to find it?</p>
