I need a prototype done in this way:

Array.prototype.getname=function(){ [...]return arrayname; }

So I can:

z=new Array;

alert(z.name);

and I should have z in the alert.

I'm working on Chrome and caller/callee seem to return empty.

So For now the best answer is Elijah's

More generally:

Object.prototype.getName = function () { 

  var prop; 

  for (prop in self) {

     if (Object.prototype.hasOwnProperty.call(self, prop) && self[prop] === this && self[prop].constructor == this.constructor) { 

       return prop; 

     } 

  } 

  return ; // no name found 

};

I wonder if there are better solutions.
