How do I determine scrollHeight?

How do I determine scrollHeight of a division use css overflow:auto?

I've tried:

$('test').scrollHeight();
$('test').height(); but that just returns the size of the div not all the content

Ultimately, I'm trying to create a chat and always have the scroll bar to the current message on the screen.

So I was thinking something like the following:

var test = $('test').height();
$('test').scrollTop(test);

Thank you,

Correct ways in jQuery are -

• $('#test').prop('scrollHeight') OR
• $('#test')[0].scrollHeight OR
• $('#test').get(0).scrollHeight

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

You can also use:

$('#test').context.scrollHeight
