Question

I have a problem I need to solve regarding my Javascript code. When instantiating object (in this case adding new members) I want the members to get unique ids. Below is a simplified version of my code to give you a picture of what I want. What is the best way to do this?

function Member(name){

    //unique id code...

    this.getName = function(){
        return name;
    }

    this.setName = function(_name){
        name = _name;
    }
}

I guess its easy as:

(function() {
    var idcounter = 0;

   function Member(name){
        this.id = idcounter++;
        this.getName = function(){
            return lastName;
        };

        this.setName = function(_name){
            name = _name;
        };
   }

   yournamespace.Member = Member;
}()); 

yournamespace should be your application object or whatever. You also could replace it with window in a browser, to have the Member constructor global.
