JavaScript constructors using JavaScript object literal notation

Question

What is the best way to build constructors in JavaScript using object literal notation?

var myObject = {
 funca : function() {
  //...
 },

 funcb : function() {         


        

Answer 1

Make the object a function, like this:

var myObject = function(arg1){
  this.funca = function(){
    //...
  };
  this.funcb = function(){
    //...
  };
  this.constructor = function(obj){
    alert('constructor! I can now use the arg: ' + obj.name);
  };
  this.constructor(arg1);
};

// Use the object, passing in an initializer:
var myVar = new myObject({ name: 'Doug'});
