AS与JS互相通信
不说废话，直接贴代码。。。
AsJsComm.as
package {import flash.display.Sprite;import flash.external.ExternalInterface;public class AsJsComm extends Sprite {/** * 构造函数 */public function AsJsComm() {// 注册一个AS方法供JS调用ExternalInterface.addCallback('callback', callback);// AS调JS方法(此alert为window对象的alert方法)ExternalInterface.call('alert', 'AS: Hello JS!');}/** * 回调方法 */public function callback(str:String):void {// 为了方便查看，直接调用JS的弹框ExternalInterface.call('alert', str);}}}

1、只要html页面中能正常访问的JS方法，AS中都可以直接用ExternalInterface.call调用，不需要另作其他声明；
2、AS中的方法要供JS调用，必须先调用ExternalInterface.addCallback注册，注册的方法会绑定在html页中flash元素的object对象上；
3、没了。。。
