Flex操作Json数据示例

Flex操作Json数据示例

本示例中需要用到JSON类库，下载地址：http://code.google.com/p/as3corelib/

1、Flex代码

<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <!--[CDATA[ import com.adobe.serialization.json.JSON; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; import mx.messaging.AbstractConsumer; import mx.rpc.http.HTTPService; private var strServiceUrl:String = "http://localhost:4051/WebSite/CreateJson.aspx"; private function getJsonData(event:MouseEvent):void { var service:HTTPService = new HTTPService(); service.url = strServiceUrl+"?"+new Date().toUTCString(); service.useProxy = false; service.resultFormat = "e4x"; service.addEventListener(FaultEvent.FAULT,onFaultHandler); service.addEventListener(ResultEvent.RESULT,onResultHandler); service.send(); } private function onResultHandler(e:ResultEvent):void { txt.text = ""; var str:String = e.result.toString(); var jsonObj:Object = JSON.decode(str); txt.text += jsonObj.name; } private function onFaultHandler(e:FaultEvent):void { var str3:String = e.message.toString(); trace(str3); } ]]--> </mx:Script> <mx:Button x="78" y="43" label="获取解析JSON" click="getJsonData(event)"/> <mx:TextArea x="68" y="101" id="txt" width="409" height="236"/> </mx:Application>

2、HttpService代码

string strMsg = "{\"name\":\"jiang\",\"age\":26}"; Response.Write(strMsg);
