也許這是可行的使用JS eval從Actionscript方面,但我認爲有一個副本。
讓你的swf調用一個JS代理,然後將消息廣播給註冊的監聽器。
東西沿着這些路線:
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');
}
}
這可以簡化,如果你硬編碼更多的東西,但也許這種方法並不複雜,以實現並給出你有一定的靈活性,並使註冊聽衆容易JS「客戶端」(涉及更多的部分將在ProxyDispatcher本身)。
希望這是有道理的!
