JavaScript与ActionScript通讯(ExternalInterface类)
需要引入import flash.external.ExternalInterface;
一、ActionScript调用JavaScript的方法
这里要用到ExternalInterface类的call方法
ExternalInterface.call(functionName:String,...arguments):*
fuctionName:要调用的JavaScript函数名
arguments:参数,可选
1.不带参数的情况
JavaScript:function Show() { alert("I am a func!");}
ActionScript://直接用一条语句调用ExternalInterface.call("Show");
2.带参数的情况
JavaScript:function Show(message) { alert(message);}
ActionScript:ExternalInterface.call("Show","I am a message from AS"); 另外,也可以用getURL方法来调用
getURL("javascript:show('i am a message from as)","_self");
二、JavaScript调用ActionScript的方法
这要用到ExternalInterface类的addCallback方法
ExternalInterface.addCallback( functionName:String, closure:Function):void
functionName:要注册的函数名
closure:对应的执行函数
ActionScript:ExternalInterface.addCallback("Show",OnShow);private function OnShow(message:String):string{return message;}
JavaScript:function thisMovie(movieName){ if(navigator.appName.indexOf("Microsoft") != -1){ return window[movieName]; }else{ return document[movieName]; }} function CallAS( ) { thisMovie("ViewLesson").Show("i am a message from js");//ViewLesson是flash媒体的ID}
