推荐答案

ExternalInterfaceUtil.addExternalEventListener（window.onunload，handleLogout，unloadFlex）;

ExternalInterfaceUtil.addExternalEventListener("window.onunload", handleLogout, "unloadFlex");

package
{
    import flash.external.ExternalInterface;

    public class ExternalInterfaceUtil
    {
    	public static function addExternalEventListener( qualifiedEventName:String, callback:Function,callBackAlias:String ):void
    	{
    		// 1. Expose the callback function via the callBackAlias
    		ExternalInterface.addCallback( callBackAlias, callback );
    		// 2. Build javascript to execute
    		var	jsExecuteCallBack:String = "document.getElementsByName('"+ExternalInterface.objectID+"')[0]."+callBackAlias+"()";
    		var jsBindEvent:String = "function(){"+qualifiedEventName+"= function(){"+jsExecuteCallBack+"};}";
    		// 3. Execute the composed javascript to perform the binding of the external event to the specified callBack function
    		ExternalInterface.call( jsBindEvent );
    	}
    }
}

我不记得在那里我从得到这个，但我用它和它的作品pretty的好。当然，并不是所有的浏览器都将进行合作，但总比没有好......

I don't remember where I got this from, but I've used it and it works pretty well. Of course not all browsers are going to cooperate, but it is better than nothing...
