Access other top window by name

[simon.niederberger]

Hi all

I'm developing a web-app for IE (7, 8) which has following reporting
feature:

The main window of the application contains a menu and some other
buttons, plus an IFRAME hosting the current application page. The main
window is 'load once'. Reports open in a new 'top' window (i.e. new
tab or new window, depending on the user's IE settings). Reports may
contain links. If the user clicks on a link, it should open in the
IFRAME of the main window.

top1: main window -> IFRAME
top2: report window with Links

Setting a 'target' on the links to the IFRAMEs name (or that of
iframe.contentWindow) doesn't work. It seems to me that the report
window is simply not aware of the IFRAME in the other window. As both
windows originate from the same domain, I guess cross-site scripting
shouldn't be an issue and somehow I should be able to get hold of the
other window. If yes, I could set the src there with Javascript.

report window: a href="#" onclick="loadLinkInIframe('targeturl.html')"

function loadLinkInIframe(targeturl) {
var topwnd = WHAT GOES HERE?
var ifrm = topwnd.frames['bodyframe'];
ifrm.src = targeturl;
}

Thanks
Simon

I'm not sure if your design is optimal, but 'window.opener()' should
normally refer to the page that opened the current window.

IIRC there might be some compatibility issues.

Hi Bart

Thanks for the reference. Apparently the window.opener is something to
be used with window.open() and only works for frames (frame, iframe).
In my case a form post will have a target='_blank', so that new window
will know nothing of it's originator. The new window does however have
the window name, so if there is a window collection or something
(ideally: navigator.getWindowByName()), I could get a reference to
that window object and continue from there.

Hi Bart

I take everything back, your a hero. window.opener is in fact set for
a window created by a

<form target='_blank'>

and points directly to the contentWindow of the IFRAME is was looking
for. So now it's just

window.opener.location = mytargeturl;

Thanks a bunch
Simon
