也许这是可行的使用JS eval从Actionscript方面,但我认为有一个副本。
让你的swf调用一个JS代理,然后将消息广播给注册的监听器。
东西沿着这些路线:
JS
var proxyDispatcher = new ProxyDispatcher();
var app = getYourSwf("myswf");
// tell your app to call the dispatch method in the proxyDispatcher object everytime theres a timeupdate
// dispatch will receive the name of the event back, plus the "payload" data (that's up to you to define)
app.registerCallback('proxyDispatcher.dispatch','timeupdate');
// now, add "clients" here
// the idea is that proxyDispatcher registers JS functions to be called when its dispatch method is called
// so, when dispatch is called with 'timeupdate' as the event type, call all listeners for 'timeupdate'...
proxyDispatcher.addEventListener('timeupdate',function() {
});
AS
var _map:Object = {};
private function handleRegisterCallback(jsCallback:String,eventName:String):void {
_map[eventName] = jsCallback;
}
// when there's a timeupdate, check if you have a registered listener for it; if so, call it
private function dispatchTimeupdate():void {
if(_map['timeupdate']) {
// call the registered function, pass the event name and any data you need
ExternalInterface.call(_map['timeupdate'],'timeupdate','your data here');
}
}
这可以简化,如果你硬编码更多的东西,但也许这种方法并不复杂,以实现并给出你有一定的灵活性,并使注册听众容易JS“客户端”(涉及更多的部分将在ProxyDispatcher本身)。
希望这是有道理的!
