Flex 調用Web Service 之使用Flex Builder 產生的proxy Code之ActionScript呼叫~~

接續前一篇,
Service proxy已經產生完畢,
本篇使用ActionScripts來呼叫Service,
以下是範例程式碼~

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="initApp()"> <mx:Script> <![CDATA[   import generated.webservices.*;   import mx.rpc.events.FaultEvent;   import mx.controls.Alert;   public var ws:Service1; //宣告ws   //application initial時會呼叫的程式   public function initApp():void   {     ws=new Service1(); //建立 Service1的 instance   }   //當User按下按鈕,呼叫的Function   public function callHelloWorld(echo:String):void{     // 建立呼叫helloWorldEvent的Listener,     // 有回應則呼叫handleEchoResult     ws.addhelloWorldEventListener(handleEchoResult);     //呼叫operation     ws.helloWorld(echo);   }   //當呼叫operation後，有任何 Response時，Listener會呼叫本function   public function handleEchoResult(event:HelloWorldResultEvent):void{     this.txt_result.text=event.result; //將結果傳給input_text   } ]]> </mx:Script> <mx:TextInput x="82" y="55" id="txt_result"/> <mx:Button x="82" y="85" label="呼叫Service" id="btn_callService" click="{callHelloWorld('island123');}" /> </mx:Application>
