IFrame problem

[computerzworld]

Hello,
I am having one frame & it is having menu items inside it and on clicking that menu one javascript function is called and it replaces content of one html page, I am having one span and I want to replace its contents when user clicks on menu items. But I am unable to access span using its id.

I am trying to replace span contents something like this,

document.getElementById('contentSpan').innerHTML = text;

But I am unable to do so. If I use simple HTML in menu instead of iframe then it works fine. But it doesn't works for iframe. What should be the problem behind it? Please help me.... Thanks in advance...

The content of an iframe is a separate document from the iframe's container; elements of one are not elements of the other.

It's been years since I've had a use for iframes, but I think the document contained by the iframe object can be reached with iframe.contentDocument; the rest is the same as before.

At least, that's what Firebug tells me with twenty seconds' worth of playing around.

Somehow, though, I suspect that security restrictions might get in the way.
