导读：javascript调用Flex 1.其中movieName 为param name="movie" value="main.swf" / function thisMovie(movieName){if(navigator.appName.indexOf("Microsoft")!=-1){return window[movieName];}else{return document[movieName];} } 1. 获取flex对象，查找方法

javascript调用Flex

 1.其中movieName 为<param name="movie" value="main.swf" />
          function thisMovie(movieName){
		if(navigator.appName.indexOf("Microsoft")!=-1){
			return window[movieName];
		}else{
			return document[movieName];
		}
          }       
             1. 获取flex对象，查找方法并调用      
                   thisMovie("main").callFromJavaScript(document.getElementById("value").value);
1.添加Javascript 可以访问Flex的资源到容器内！
2.其中第一个参数为JavaScript调用Flex资源的Flex资源别名
3.其中Flex的访问范围如private在javascript中也能访问
 ExternalInterface.addCallback("callFromJavaScript",callFromJavaScript2); 

Flex调用javascript
 ExternalInterface.call("getFromFlex",valueForJavascript.text);
