Closing pop-up based on external server response

rogair

I am developing an interface that will pass the user to an external system in a pop-up window. When they have completed that piece of the process the external system will be posting data back to my servers. I need to be able to close the pop-up window when the postback occurs. I can not figure out how a postback that doesn't involve the client browser will be able to affect the pop-up window.

Any ideas?
Thanks.

That sounds like you're trying to do server-push.

There is no commonly supported sensible method of doing server-push from an AJAX-type application. It can be done, but all the methods involve unspeakably disgusting hacks.

Mozilla supports a multipart extension to XHR which enables server push, but this is not supported by anything else either.

Therefore, unless it's a major problem, I suggest you use polling via a conventional XMLHttpRequest.

Ok, that's pretty much what I've been finding. I actually found a decent work around using an <iframe> set (<iframes> have to be set on client requirement, no choice there> and db checks. Trouble is now I can't seem to close the window from within an <iframe>.

I open a window with:

<SCRIPT LANGUAGE="JavaScript">
<!--
function UploadMedia(newURL, newName, newFeatures, orgName) {
var remote = open(newURL, newName, newFeatures);
if (remote.opener == null)
remote.opener = window;
remote.opener.name = orgName;
return remote;
}

function launchRemote() {
myRemote = UploadMedia("http://www.domain.com/file", "WinName", "height=580,width=600,channelmode=0,dependent=0,directories=0,fullscreen=0,location=0,menubar=0,resizable=1,scrollbars=1,status=0,toolbar=1", "myWindow");
}

// -->
</SCRIPT>

The window contains a page with two <iframe> sets. This loads fine and behaves properly. The trouble is when I do a close event either with:
<BODY onLoad="window.close();"> within the iframe does nothing (probably referrs to the iframe, not outer window.

It returns an error that "WinName" is not defined. Though it should be as that's the window that was opened. What am I missing here?

You need to find the appropriate frame. Perhaps window.frames.top will point at the right frame. Look at the Javascript DOM documentation (e.g. on developer.netscape.com originally, perhaps on developer.mozilla.org now) for more info.

Then call the "close" method of that frame's window object.
