调用 Javascript 的 window.onebeforeunload 时调用 ActionScript function

Question

I would like to call my function ActionScript closeApp:

public function closeAutorun(event: CairngormEvent): void {
    Alert.show(
        LMSModel.ERR_MESS_QUESTION,
        LMSModel.ERR_MESS_TITLE,
        3,
        FlexGlobals.topLevelApplication as Sprite,
        alertClickHandler);
}

When the user close the tab or the navigator.

Any suggestions?

Thx

In actionscript, at the start of your program:

if (ExternalInterface.available) {
   ExternalInterface.addCallback("closeAutorun", closeAutorun);
}

In javascript:

window.onbeforeunload = confirmClose;
function confirmClose() {
  document.getElementById('app').closeAutorun();
}

where 'app' is the id of the swf instance.
