AS3程序。随机化项目的顺序组合框的XML(AS3 Procedural. Randomise

我试图读取XML文件和所有的元素添加到组合框随机顺序（我不知道如何做到这一点）。我公司生产的在舞台上的ComboBox称为Primary_CB。我有我的XML都在下面的格式设置...

<data>

<elements>

    <element1>
        <primary>Male Character</primary>
    </element1>
    <element1>
        <primary>Female Character</primary>
    </element1>

</elements>

</data>

我的AS3基本上读取XML文件和内容填充到像这样的组合框...

Primary_CB.prompt = "Items";

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("IdeaElements.xml"));

function LoadXML(e:Event):void
{
    xmlData = new XML(e.target.data);
    trace(xmlData..primary.length());
    for (var i:uint=0; i<xmlData..primary.length(); i++)
    {
        xmlAry.push(xmlData..primary[i]);
        xmlURL.push(xmlData..url[i]);
        Primary_CB.addItem( { label: xmlAry[i], data:i } );
        Primary_CB.addEventListener(Event.CHANGE, action);
    }
}

function action(e:Event):void
{
    var no:Number = Number(Primary_CB.selectedItem.data);
    trace(xmlURL[no]);
}

我将如何使它随机元素的顺序，还可以在列表中添加的第一个元素的组合框的提示？

Answer 1:

Primary_CB.prompt = "Items";

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("IdeaElements.xml"));

function LoadXML(e:Event):void
{
    xmlData = new XML(e.target.data);
    trace(xmlData..primary.length());
    var tempXMLAry:Array = new Array();
    var tempUrlAry:Array = new Array();
    var i:uint;
    for (i = 0; i<xmlData..primary.length(); i++)
    {
        tempXMLAry.push(xmlData..primary[i]);
        tempUrlAry.push(xmlData..url[i]);
    }
    var tLen:int = tempXMLAry.length; // Store that value as it is here, because it will change during the loop
    for (i = 0; i < tLen; i++) {
        var rnd:int = Math.round(Math.random() * (tempXMLAry.length - 1));
        xmlAry.push(tempXMLAry[rnd]);
        xmlURL.push(tempUrlAry[rnd]);
        tempXMLAry.splice(rnd, 1);
        tempUrlAry.splice(rnd, 1);
    }
    for (i = 0; i < xmlAry.length; i++) {
        Primary_CB.addItem( { label: xmlAry[i], data:i } );
    }
    Primary_CB.selectedIndex = 0;
    Primary_CB.addEventListener(Event.CHANGE, action);
}

function action(e:Event):void
{
    var no:Number = Number(Primary_CB.selectedItem.data);
    trace(xmlURL[no]);
}

这是我想出了。这是非常相似，你已经有了一个。什么情况是：
