加載數據從XML組合框

Question

我的XML看起來如下

<?xml version="1.0" encoding="utf-8"?> 
<Images> 
<Image imgID = "1" > 
     <imgName>"Angelina Jolie"</imgName> 
      <url>"Angelina Jolie.jpg"</url> 
</Image> 

<Image imgID = "2" > 
    <imgName>"Big B"</imgName> 
    <url>"Big B.jpg"</url> 
</Image> 

<Image imgID = "3" > 
    <imgName>"Brad Pitt"</imgName> 
    <url>"Brad Pitt.jpg"</url> 
</Image> 

<Image imgID = "4" > 
    <imgName>"Mohanlal"</imgName> 
    <url>"Mohanlal.jpg"</url> 
</Image> 

<Image imgID = "5" > 
    <imgName>"Prithviraj"</imgName> 
    <url>"Prithviraj.jpg"</url> 
</Image> 
<Image imgID = "6" > 
    <imgName>"Tom Cruise"</imgName> 
    <url>"Tom Cruise.jpg"</url> 
</Image> 
</Images> 

在我的文件夾我有XML，如圖所示。該文件夾中有6個圖像，名稱以urls的形式給出。我在舞臺上有一個組合框。它的名字是myCB。有一個圖像保持器imgHolder_mc。

我有兩個任務。

使用imageNames填充組合框。

根據選擇的圖像名稱，圖像保持器中的圖像必須更改。必須使用圖片網址來檢索圖片。

這是我做過到目前爲止

import fl.data.DataProvider; 

myCB.prompt = "Select Image:"; 
var model_dp:DataProvider = new DataProvider(xmlData); 
myCB.dataProvider = model_dp; 



// Creates the variable(s) to load the XML externally 
var xmlLoader:URLLoader = new URLLoader(); 
var xmlData:XML = new XML(); 

// Ensuring that we do not prematurely start fiddling with the XML data until all of our data has been loaded 
xmlLoader.addEventListener(Event.COMPLETE, LoadXML); 
// We call our xmlLoader's load method 
xmlLoader.load(new URLRequest("Images.xml")); 

function LoadXML(e:Event):void { 
    xmlData = new XML(e.target.data); 
    trace(xmlData..imgName); 

} 

跟蹤給我

<imgName>"Angelina Jolie"</imgName> 
<imgName>"Big B"</imgName> 
<imgName>"Brad Pitt"</imgName> 
<imgName>"Mohanlal"</imgName> 
<imgName>"Prithviraj"</imgName> 
<imgName>"Tom Cruise"</imgName> 

請根據選擇諮詢我，我怎麼能結合這我的組合框，然後選擇圖片我在組合框中製作。

Answer 1

myCB.prompt = "Select Image"; 
var xmlLoader:URLLoader = new URLLoader(); 
var xmlData:XML = new XML(); 
var xmlAry:Array = new Array(); 
var xmlURL:Array = new Array(); 
xmlLoader.addEventListener(Event.COMPLETE, LoadXML); 
xmlLoader.load(new URLRequest("Images.xml")); 
function LoadXML(e:Event):void { 
    xmlData = new XML(e.target.data); 
    trace(xmlData..imgName.length()); 
    for(var i:uint=0;i<xmlData..imgName.length();i++) 
    { 
     xmlAry.push(xmlData..imgName[i]); 
     xmlURL.push(xmlData..url[i]); 
     myCB.addItem({ label: xmlAry[i], data:i }); 
     myCB.addEventListener(Event.CHANGE, action); 
    } 
} 
function action (e:Event):void 
{ 
    var no:Number = Number(myCB.selectedItem.data); 
    trace(xmlURL[no]); 
}
