checking for scrollHeight of an element sometimes returning 0

Question

So I am checking the the scrollHeight of some dynamically generated content to determine whether or not to include a more button in the content. The user can click the more

I would recommend looking at these (I couldn't locate a similar link for Chrome):

It seems that scrollHeight is only valid if something is large enough to need to scroll, so I would assume that 0 means no scrolling needed (all content is visible). From looking at the above links, maybe what you want is clientHeight.
