JavaScript与ActionScript通讯
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
2.带参数的情况
JavaScript
ActionScript
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
}
