Events with IFRAME auto scroll

[fixthebug2003]

Hi,
I have an IFrame with scrolling attribute set to "auto".
When the data in the IFrame exceeds the height of the IFRAME, the vertical scroll bar automatically appears.

My Question is : is there an Event that fires when the vertical scroll bar appears..ie when the data in the IFRame exceeds the height of the IFRAME?

there is no Event as such but u can trap it:

if(document.body.clientHeight<document.body.scrollHeight)
{
alert("Hey its a scrollbar!!!!")
}

place this code at the end of all ur HTML code...

You should be able to trap the onresize event of the body, and then use vbkris's code in that event to test for the presence of a scrollbar or not.

Hope this helps,

Oh. Scrap that - the body has no onresize event )
