（續）flex讀取本地檔案XML

首先寫一個AS類.

ReadData.as類如下所示：

package com.utils.allas
{
	
	/**
	 * *
	 * 不寫接口，直接寫實作類
	 * 
	 * */
	
	import flash.events.Event;
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	
	import mx.controls.Alert;
	import mx.events.FlexEvent;
	import mx.utils.StringUtil;
	
	public class ReadData
	{
		private var loader:URLLoader = new URLLoader();
		private var request:URLRequest = new URLRequest("../config/data.xml");
		
		public static var reaDdate: ReadData = null;
		

		
		public var ipUrl:String;
		//這是一個URL，其實是一個XML檔案
		
		
		//相關跳轉連結
		public var _ip_value :String;
		public var _iframeurl_values:String;
		public var _iframeurl_values_sr:String;
		public  var _iframe_values_qone_zl:String;
		public var _iframe_values_qone_cb:String;
		public var _iframe_values_qone_jd:String;
		public var _iframe_values_qone_zt:String;
		public static var _elapse_timer:String;
		
		
		//URL集合
		public  var UrlArr:Array;
		
		
		public function  get ip_value():String
		{
			return _ip_value;
		}
		

		
		public function get iframeurl_values():String
		{
			return this._iframeurl_values;
		}

		public function get iframeurl_values_sr():String
		{
			return this._iframeurl_values_sr;
		}

		public function get iframe_values_qone_zl():String
		{
			return this._iframe_values_qone_zl;
		}

		
		public function get iframe_values_qone_cb():String
		{
			return this._iframe_values_qone_cb;
		}

		
		public function get iframe_values_qone_jd():String
		{
			return this._iframe_values_qone_jd;
		}

		
		public function get iframe_values_qone_zt():String
		{
			return this._iframe_values_qone_zt;
		}

//		public function get elapse_timer():String
//		{
//			return this._elapse_timer;
//		}
//
//		public function set elapse_timer(_elapse_time:String):void{
//			this._elapse_timer=_elapse_time;
//		}
		public static function getInstence() : ReadData{
			 if (reaDdate == null) {
				 reaDdate = new ReadData();
			 }
			 return reaDdate;
		}
		
		//加載這個構造器
		public function ReadData()
		{
			// TODO Auto-generated method stub
			loader.load(request);
			//	Alert.show(loader.data);
			loader.addEventListener(Event.COMPLETE, onComplete);     
		}
		
		//事件響應函數
		private function onComplete(event:Event):void
		{
			var loader:URLLoader = event.target as URLLoader;
			if (loader != null)
			{
			
				//開始嘗試使用Array方式
//				ipUrl = StringUtil.trim(loader.data);
//				//UrlArr = ipUrl.split("\r");
				
				var xml:XML=XML(event.target.data);   

				trace(xml.toString());
				
				
				_ip_value=xml.ip[0][email protected];
				_iframeurl_values=xml.ip[1][email protected];
				_iframeurl_values_sr=xml.ip[2][email protected];
				_iframe_values_qone_zl=xml.ip[3][email protected];
				_iframe_values_qone_cb=xml.ip[4][email protected];
				_iframe_values_qone_jd=xml.ip[5][email protected];
				_iframe_values_qone_zt=xml.ip[6][email protected];
				_elapse_timer=xml.ip[7][email protected];
			
				
//				trace("共有"+UrlArr.length+"記錄");
//				trace("時間:\t"+_ip_value);
	
			}
			else
			{
				Alert.show("不可以加載URLLoader類!");
			}
		}
		
		public function get ipUrlR():String{
		   return ipUrl;
		}
		
		
		
		
	}
}
           

然後在mxml檔案中使用:

getValueFromNativeFile.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" 
			   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
			   initialize="application1_initializeHandler(event)"
			   creationComplete="application1_creationCompleteHandler(event)"
			   
			   >
	<fx:Declarations>
		<!-- 将非可視元素（例如服務、值對象）放在此處 -->
	</fx:Declarations>
	
	<fx:Script>
		<![CDATA[
			import com.utils.allas.ReadData;
			
			import mx.controls.Alert;
			import mx.events.FlexEvent;
			
			public var rd:ReadData;
		

			protected function application1_initializeHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
				 
				rd = ReadData.getInstence();
				

			}
			
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
				if (rd != null) {
					Alert.show(rd._iframeurl_values_sr);	 
				}
				
			}
			
		]]>
	</fx:Script>
	
</s:Application>
           

而用到的xml檔案為:

data.xml:

<?xml version="1.0" encoding="UTF-8"?>  
<ips>  
               <ip data="http://192.168.17.22:8080" tp="IP_valuse"/>   
               <ip data="http://192.168.17.101/ppar/" tp="IFrameURL_valuse"  />   
               <ip data="http://www.gzios.com/ppar/bbs/forum.php?mod=viewthread&tid=215&extra=" tp="IFrameURL_valuse_SR"/>   
               <ip data="http://gz.iscas.ac.cn:8080/pm/hl/QualityMonitorAction.do?method=getQualityMonitor_tree&uuid=nZFQlgRWtN6LJCnbVNai1MTXAvwIoJY2" tp="IFrameURL_valuse_Qone_ZL" />   
               <ip data="http://gz.iscas.ac.cn:8080/pm/hl/CostMonitorAction.do?method=getCostMonitor_tree&uuid=pq0q0M8iY3wfIUxSsWoQYL4hF7MjgmZB" tp="IFrameURL_valuse_Qone_CB" />   
               <ip data="http://gz.iscas.ac.cn:8080/pm/hl/ProgressMonitorAction.do?method=getProgressMonitor_tree&uuid=dUmn2pb3vLTjg7Hok6iT5hOH6nTR7365" tp="IFrameURL_valuse_Qone_JD" />   
               <ip data="http://gz.iscas.ac.cn:8080/pm/hl/ProjMonitorAction.do?method=getAllMonitor_tree&uuid=vBEiHa4vjku3vrqFMEeFNlY6ktdjHzYa" tp="IFrameURL_valuse_Qone_ZT" />   
               <ip data="30000" tp="ElapseTimer" />                
</ips>  
 
           

注意： 在oncomplete函數是要經過兩次回調才能傳回，是以在mxml檔案一個方法中(比如initial方法）中要先new出一個新類，然後在另一個方法createcomplete方法中實作變量讀取與顯示。
