Question

flash调用js失败，不知道是什么原因

as代码：
package {

import flash.display.MovieClip;
import flash.events.MouseEvent;
import flash.external.ExternalInterface;

public class HelloWorld extends MovieClip {

public function HelloWorld() {
// constructor code
btnHelloWorld.addEventListener(MouseEvent.CLICK,onClick);
}
private function onClick(me:MouseEvent):void{
ExternalInterface.call("Show");
}
}

}

btnHelloWorld是一个按钮，想点击按钮时调用js中的show

Answer 1

先判断下ExternalInterface.available.
