Flex 和 javascript的交互

Flex 和 javascript的交互

index.jsp 页面 ；在index.jsp页面中嵌入了<Object ../>，对应IndexApplication.mxml编译后的SWF文件

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
			id="WelcomeSWF" width="0" height="0"
			codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
			<param name="movie" value="welcomeModule.swf" />
			<param name="quality" value="high" />
			<param name="bgcolor" value="#869ca7" />
			<param name="allowScriptAccess" value="sameDomain" />
			<embed src="welcomeModule.swf" 
				width="0" height="0" align="middle"
				loop="false"
				type="application/x-shockwave-flash"
				>
			</embed>
</object>

1、Flex调用javascript中的方法

   index.jsp

  

<script type="text/javascript">
	
		
	function failToLogon(){
		alert("用户名、密码错");
	}
		

   </script>   

   IndexApplication.mxml

   ExternalInterface.call("failToLogon");

2、javascript调用Flex的方法

  IndexApplication.mxml

  public function init() : void{
	ExternalInterface.addCallback("logonFunction",logon);//在creationComplete 是要注册方法,
   }

  public function logon(username : String,password : String) : void{
            	      		
   }

  index.jsp中

 <script type="text/javascript">
	
	function logonClick(){
				
		var v = WelcomeSWF.logonFunction(username.value,password.value);//WelcomeSWF对应Object的ID，logonFunction是Flex中注册的方法
				
	}
	
  </script>
