how to access a popup's iframe parent 1

[stevelionbird]

I'm trying to modify a js based html editor and what I need to do seems quite simple but I'm having trouble.

The editor loads in an iFrame, and the iFrame launches a popup window. Within the popup window, I need to determine the URL of the page that contains the iFrame.

I've tried

parent.document.URL

but that gives me the URL of the iFrame page .. so I guessed that

parent.parent.document.URL

might work but that yielded the same.

Is there a way from a popup window (which is opened by an iFrame) to determine the URL of the page that contains the said iFrame?

Thanks in advance,
Steve

you need to use "opener" to get a reference to the window (or frame) that opened a popup. E.g.:

alert(opener.location);

Hope this helps,

Thanks Dan,

I was able to get the URL of the page I needed using the following:

alert(parent.opener.parent.location);

However this worked in Firefox but not IE..

Is there something syntactically wrong/non-standard with the above code, or at least another way to write it so that IE would recognize too?

Thanks again,
Steve

"opener" should always come first if the code is inside a popup window, I believe. Try re-ordering the properties.

Ok I think I've identified the problem.

The HTML editor I'm using (FCKeditor) uses showModalDialog() to open the popup if it detects IE and after trying different variations of the window.opener syntax discussed above, it (opener) seems to be undefined every time in IE.

So, does anyone know if the popup generated using this showModalDialog() method is treated differently in the object model / how I could refer to it's opener .. assuming of course it is indeed different than the syntax posted previously?

many many thanks for any help on this!

I've figured it out...

opener is not defined for modalDialog, instead, I found what I needed nested in the window.dialogArguments object.

Thanks for your help Dan as what you posted will work in every other situation except for this special case with IE where showModalDialog() is used in place of window.open()

Best,
Steve
