I am getting 'Permission denied' on the window.opener.closed statement. I don't think it is a cross domain issue because the reload works fine when the parent exists. How can I check if the parent exists on IE ? I tried window.opener.location and window.opener.document.all
Thanks
I wouldnt be able to tell you whether or not you're really experiencing a permissions error as that would really depend on your specific situation...
But if it were me, the way I would go about telling a if a parent window is closed or not is by using a try/catch construct and trying to set properties on the parent window's objects. Keep in mind, this will only produce accurate results if you are on the same domain.
Example:
<HTML>
<HEAD>
<SCRIPT language="javascript">
function checkParent() {
try {
window.opener.document.title = window.opener.document.title;
return "Parent Window is Open!";
}
catch(e) {
return "Parent Window is Closed!";
}
}
</SCRIPT>
</HEAD>
<BODY>
<BUTTON onclick="alert(checkParent())">checkParent()</BUTTON>
</BODY>
</HTML>
I'm having identical problems. The try/catch solution works great, and I'm grateful for the solution. The behavior still makes me feel queasy, though. Can anyone explain the root problem?
In my case, I have an object with a property set to a "dependent" window that I opened. When I close that dependent window by selecting its close button, then doing "if (myobject.windowproperty && !myobject.windowproperty.closed)" from the parent window throws the permissions error. It acts kinda as if windowproperty were an invalid, but nonnull pointer.
Thats just sort of the way IE works. Ive been through all available documentation on IE in MSDN numerous times as I develop HTAs regularly and I havent come across an explaination as to why IE behaves that way.
Some things Ive just learned to accept...
