Object Oriented Javascript Problem

[puffpio]

is there anyway to set the callback to the particular instance of the object that intiiated it?

here's my sample code class:

-------------

function MyClass() {}

MyClass.prototype.GetStuff = function()
{
var myAJAX = new AJAX();
myAJAX.sendBegin("somewebservice", "HandleGetStuff"); // this needs to be changed somehow
}

MyClass.prototype.HandleGetStuff = function(incoming)
{
// do stuff with incoming
}

--------------

later on in the code:

---------------

var myClass1 = new MyClass();
var myClass2 = new MyClass();

myClass1.GetStuff(); // should be handled by it's own HandleGetStuff
myClass2.GetStuff(); // ditto

Instead of "HandleGetStuff", try self.HandleGetStuff without quotes.

You'll need to learn more about javascript scope rules. Try this:
MyClass.prototype.GetStuff = function()
{
var myAJAX = new AJAX();
var instance = this;
myAJAX.sendBegin("somewebservice", function (arg1, arg2, arg3) {
instance.HandleGetStuff(arg1, arg2, arg3);
});
}

The cleaner way to accomplish this is to add a "bind" method to the Function prototype (or the entire prototypejs library).
Take a look here: http://www.prototypejs.org/api/function/bind
Then change your class to:
MyClass.prototype.GetStuff = function()
{
var myAJAX = new AJAX();
myAJAX.sendBegin("somewebservice", this.HandleGetStuff.bind(this));
}
