Why is onbeforeunload message missing in dialog?
I have this:
...
<script type="text/javascript" src="SLError.js" ></script>
<script type="text/javascript">
function NotifyWebserviceOnClose(e) {
var SLPlugin = document.getElementById("SL");
var dirty = SLPlugin.Content.ViewModel.DataIsDirty();
window.onbeforeunload = null;
if (dirty) {
var msg = 'Changes have not been saved!';
var e2 = e || window.event;
if (e2) {
e2.returnValue = msg;
}
return msg;
}
return;
}
window.onbeforeunload = NotifyWebserviceOnClose;
</script>
</head>
<body >
<form id="form1" runat="server" style="height:100%" >
<div id="silverlightControlHost">
<object id="SL" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
...
In IE 9, it shows the returned message. In FF 4, it doesn't
