Question

I am very new to javascript prototypes. So I am wondering If the following is legal and will always work :

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

and then :

var obj1 = new Obj("one");
var obj2 = new Obj("two");
alert(obj1.getName() + " " + obj2.getName());

Will I get “one two”. I know this is a simple example, but will things like this always reference object instances or will this mean the prototype or an event. Thanks

Answer 1

// Setup Obj    
function Obj() {}
Obj.prototype.me = function () {return this;}

// Make some vars
var a = new Obj(), b = new Obj();

// find out what "this" is equal to
a.me() === a; // true
a.me() === b; // false
b.me() === a; // false
b.me() === b; // true
