Flash外部接口和函数回调问题

也许从Actionscript方面使用JS eval是可行的,但是我认为有一个替代方法。

大致如下:

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() {

});

作为

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');
    }
}

希望这有意义!

您可以将它们作为Flash变量或使用ExternalInterface传入。
