Question

我对AS3非常陌生，似乎在我的头上。

我正在尝试让脚本拉出一个不同的.xml文件，这取决于从前一个场景中的数组生成菜单中选择的内容。虽然我希望它更灵活，但我愿意创建一个'if'语句来选择.xml - 但是我无法跟踪将根据所选菜单项改变的变量。

这是我目前正在使用的内容。这是灵活的版本（我仍然有希望）。就像我说的那样，我对此非常陌生，如果你需要了解更多以获得更好的图片，请告诉我。

var item_list = new Array();
var i:Number;
var total:Number;

var find_xml:XML = new XML();

// This part is what pulls from the frame that this is placed on
// The as3 script on the frame --- "page_2.load_xml("enter xml file");"
function push_array(e:Event):void{
  find_xml = XML(e.target.data);
  total = find_xml.item.length();
  for( i = 0; i < total; i++ ){
    item_list.push( { content: find_xml.item[i].content.toString() } );
  }
}

function load_xml(xml_file:String):void{
  var xml_loader:URLLoader = new URLLoader();
  xml_loader.load( new URLRequest( xml_file ) );
  xml_loader.addEventListener(Event.COMPLETE, push_array);
}

//Here is where the variable holding the .xml will go
var xml_file:String = place variable with .xml file name here;

感谢您的帮助！

---- ADDED：这是剩下的代码----

try{
  var key_str:String;
  var value_str:String;
  var param_obj:Object = LoaderInfo(this.root.loaderInfo).parameters;
  for ( key_str in param_obj ){
    value_str = String( param_obj[key_str] );
    if( key_str == "xml_file" )
      xml_file = value_str;
    break;
  }
}
catch (error:Error) {}

touch_slider.load_gallery( xml_file );

import flash.net.URLRequest;
import flash.ui.ContextMenu;

var menu:ContextMenu = new ContextMenu();
var copyright:ContextMenuItem = new ContextMenuItem( "" );
var credit:ContextMenuItem = new ContextMenuItem( "" );\

menu.hideBuiltInItems();
menu.customItems.push(copyright, credit);
this.contextMenu = menu;

function visit(e:Event){
var my_link:URLRequest = new URLRequest( "" );
navigateToURL( link, "_self" );
}

function visit_bar_slider(e:Event){
var my_link:URLRequest = new URLRequest( "" );
navigateToURL( my_link, "_parent" );
}

编辑你的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<photos>
   <config auto_play="true" auto_play_duration="5" slide_direction="left" tween_duration="0.5" tween_effect="easeInOutQuad"/>
   <photo>
      <filename>photos/ninki.jpg</filename>
      <target>_self</target>
   </photo>
   <photo>
      <filename>photos/richmond_station.jpg</filename>
      <target>_self</target>
   </photo>
</photos>

并使用此函数将它们拉入数组

var photolinks:Array = new Array();
var phototargets:Array = new Array();

function pullXMLtoArray(xml:XML):void
{
   var auto_play = xml.config.@auto_play; //a sample for pulling settings
   var photolist:XMLList = xml.photo;
   var photo:XML;
   for each (photo in photolist)
   {
      photolinks.push(String(photo.filename));
      phototargets.push(String(photo.target));
   }
}

所以，现在，你有2个不同的数组，一个用于photolinks，另一个用于phototargets ......

photolinks [1]＆amp; phototargets [1]属于同一个照片节点
