XML.onLoad event handling [MX2004]

programming flash
1

Hi. I appreciate the help!

I have a class with a XML object in it. In one of the class’ methods, I tell the XML object to load a document. Before I do that, I set up the onLoad event to call one of the class’ other methods. The problem is that in that handler function, I can’t seem to access any of my class’ data. If I try to use the “this” pointer, I’m getting the XML object not my class.

A simple example:

[AS]
class MyClass
{
var theXML:XML;
var someVariable:Number;

function MyClass()
{
theXML = new XML();
theXML.onLoad = XMLLoadHandler;
theXML.load( “testFile.xml” );
}

function XMLLoadHandler(success)
{
// This function gets called when the XML is done parsing,
// but I can’t access any of the data or methods in this class!!
// What do I need to do?
trace(someVariable); // does not exist
}
}
[/AS]

Thanks!!

For your class use this
[AS]
class MyClass extends XML
{
var theXML:XML;
var someVariable:Number;

    function MyClass()
    {
            this.theXML = new XML();
            this.theXML.onLoad = this.XMLLoadHandler();
            this.theXML.load( "testFile.xml" );
    }
    
    function XMLLoadHandler(success)
    {
            // This function gets called when the XML is done parsing,
            // but I can't access any of the data or methods in this class!!
            // What do I need to do?
            trace("this is to test my class");             // does not exist
    }

}
[/AS]

Then on your main scene in a ‘actions’ layer…add this script to call the class.
[AS]
import myClass

_root.onLoad = function()
{
var myVar:MyClass = new MyClass();
trace(myVar.ignoreWhite); //These two lines of code are 2 show that you have inheritted the XML class properties
trace(myVar.firstChild); //And to show that you can set the properties outside your class
}
[/AS]

If I havn’t understood correctly, please explain again so I can help out.

Cheers
