I have a modal IE dialog opened by the snippet below. I would like the modal to call a javascript function in the parent IE window on close, with something like this
<INPUT type=button value=Close onClick="javascript:window.opener.focus();window.opener.Navigate(EventID);">
The problem is that i get an error, stating that window.opener is null or not an object. I am open to different solutions, as long as I can on close of the modal call my function in the parent.


Thanks for you help

<html>
<head>
<form method="post" action="test2.asp" name="ErrorCheck">
<title>Test</title>
<SCRIPT language="javascript">
function modalWin() {
if (window.showModalDialog) {
window.showModalDialog("errordisplay2.asp?","Error","dialogWidth:350px;dialogHeight:500px");
} else {
window.open("errordisplay2.asp?","Error","height=350,width=500,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes");}
}
function Navigate(EventID)
{
document.frmNavigate.action="ADCheck.asp"
document.frmNavigate.EventID.value=EventID;
document.frmNavigate.submit();
}
window.onload = modalWin;
</SCRIPT>
</head>
</body>
</html>

Hello

Modal Dialog is something which is compatible with only IE (as per my knowladge). Why dont you use window.open method ??

You can call a function from the parnent window on close of this pop window like this..

<body onBeforeUnload="opener.Navigate("arg")">
pop up Window
</body>

Opening a modal window in IE will stop executing Javascript right after the call showModalDialog.
After the modal closes scripting continues, n fact showModalDialog is a function which returns a vaule.

EventID = window.showModalDialog("errordisplay2.asp?","Error","dialogWidth:350px;dialogHeight:500px");
if(EventID != null)
Navigate(EventID)

If a specify a window.returnValue property while closing the dialog, scripting from the calling window continues...

In case of multi browser situation you have to determine whether the popup is modal (IE) or not.
(Just check if window.opener != null)
To close the dialog (in your case it's handled by a button) you have to say :

window.returnValue = EventID;
self.close();
