How to get the current object instance name from within itself?

[Kindon]

I want to get the current instance name from within that same instansiated function.

function MyFunction() {
this.prop1 = 1;
this.prop2 = 2;

alert("My instance name: " + MyFunction.caller + "?"
}

var newFunc1 = new MyFunction();
var newFunc2 = new MyFunction();

===================================

The result should be:

"My instance name: newFunc1?"
"My instance name: newFunc2?"

===================================

The result is:

"My instance name: null?"
"My instance name: null?"

===================================


Can this be done somehow. Caller is not working as I expected. Is there some other way?

From the help:
[tt]
The caller property is only defined for a function while that function is executing. If the function is called from the top level of a JScript program, caller contains null.

That said... newFunc1 and newFunc2 are not even functions - they're variables.

Unfortunately, I'm not sure there is a way to get the name of the variable in this manner.

Mind my asking why?

There's nothing stopping you from adding a Name property to your function.

function MyFunction(sName) {
this.prop1 = 1;
this.prop2 = 2;
this.caller = sName;

alert("My instance name: " + MyFunction.caller + "?"
}

var newFunc1 = new MyFunction("newFunc1");
var newFunc2 = new MyFunction("newFunc2");

Yeah. I have done that....

I was looking for a way to do it internally. Thanks anyway though....
