فلاش + AS2.0 = تحميل ملف XML في منشئ

Question

وكيف تحميل XML باستخدام منشئ، ولست بحاجة إلى تحليل ذلك في صفيف ويمكنني استخدام Menu فئة مخصصة.

وهنا هو رمز بلادي:

class Menu {
 // XML file's filename
 private var xmlFile:String = "menu.xml";
 private var menu:XML;
 private var menuArray:Array;
 private var mainmenu:Array;

 function Menu() {
  menu = new XML();
  menu.ignoreWhite = true;
  menu.load(xmlFile);

  menu.onLoad = function(success : Boolean) : Void {
   if (success) {
    // determine how many chambers there are now
    menuArray = menu.firstChild.childNodes;
    var length:Number = menuArray.length;
    trace(length);

    // dynamic according to number of chambers
    for (var i:Number = 0; i < length; i++) {
     var sublength:Number = menuArray[i].childNodes.length;
     var submenu:Array = new Array();

     // chamber name and link
     var xmlNode:XMLNode = menuArray[i];
     submenu["name"] = xmlNode.attributes.name;
     submenu["link"] = xmlNode.attributes.link;

     // create sub-item for each chamber
     for (var j:Number = 0; j < sublength; j++) {
      var subXmlNode:XMLNode = xmlNode.childNodes[j];

      var item:Array = new Array(subXmlNode.firstChild, subXmlNode.attributes.link);
      submenu.push(item);
     }

     // create an entry for each chamber
     mainmenu.push(submenu);
    }
   }
  }
 }

 function buildMenu():Void {
  //trace(mainmenu);
 }
}

ولكن لسوء الحظ، يحصل على تحميل أي شيء.

Answer 1

Rather than creating a function inside of the constructor, I would make your load handler be a method of your class and just assign the menu.onLoad equal to that method. Otherwise I don't see any real problems, though I do tend to declare any event handlers before I call a method that could trigger that handler (i.e. setup onLoad before you call load). You may also want to add onData to see if you are getting any raw data from the load as well (onData receives one argument - the raw text of the file that was loaded).

Answer 2

I don't think you are creating your mainmenu array. You could amend the code to the following:

menu = new XML();
menu.ignoreWhite = true;
menu.load(xmlFile);

mainmenu = new Array();//add this
