[flexcoders] Catch Browser Exit with Flex

[gjessup1]

I'm having some issues with catching a browser exit with firefox. I
can get it to work with IE (not exactly how I'd like, but it works).
Does anyone have a good working example available...here is my code if
you can help from that.
Thanks

Greg

My javascript looks like this:
script language="JavaScript" type="text/javascript">
<!--
alert ("This is a Javascript Alert"); //just a message which will be
removed

// Give user a chance to save modified data
window.onbeforeunload = function() {
var warning="";
var fxControl = document.SharedObjectBoard || window.SharedObjectBoard;
 if (!${application}.unsavedAlert())
 {
        warning = fxControl.getUnsavedDataWarning();
 }

if (typeof fxControl.getUnsavedDataWarning=="function") {
warning = fxControl.getUnsavedDataWarning();
}
if (warning!="")

return warning;
else

return;
}
 -->
</script>


in my init I have ---

if ( ExternalInterface.available ) {
                        
ExternalInterface.addCallback("getUnsavedDataWarning",unsavedAlert);


Here are the functions triggered:

  private function unsavedAlert():String {
           Alert.show("Do you want to dave?", "Save Alert",
Alert.YES|Alert.NO ,this,SaveAlertHandler,null,Alert.YES);
                        //Alert.show("function");
                                                if (commitRequired) return 
UNSAVED_DATA_WARNING;
                                                else return "";
          }
          
                  private function SaveAlertHandler(e:Event):void {
                           
                            Alert.show( e.type.toString());
                  }
                                        }
