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); } } }
index.html

简要说明:
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。。。
