Working with iframe history

[musicmaster890]

Hi everybody!

I'm using iframes in my most recent WebDev project called "Felix" and would like to know how I can use Javascript to make a back button for the iframe. Here's the code I have:

<input type="button" style="width:64px" onclick="javascript:document.getElementById('pHubiframe_resource').history.go(-1)" value="&larr;Back" />

When I use that code, I get a JScript error that pHubiframe_resource doesn't support the history.go function, if I remember correctly. Thanks in advance.

UPDATE:

I've changed it to just

...onclick="javascript:history.go(-1)"...

and it works, but it opens up the possibility for my entire page to go back to a completely different page all together. Is there a way to make it so that the button becomes disabled when the first page (which is "about:blank", but it doesn't index : / )?

If you give your frames a name and access them using frames[frameName], you could call history.back() on them.
