Object Literal Stuff

var myObject = {
  property1: 'test',
  myFunc: function(arg) {
    // the 'this' object refers to the instance of the myObject variable
    this.property1 = arg;
    alert("Does this === myObject ? " + (this === myObject ? "yes" : "no") );
    var a = function() {
      // inside a closure the 'this' object is now === window

      alert("Does this === window ? " + (this === window ? "yes" : "no"));
      // Therefore, to get at myObject's properties we must use it's name
      alert(myObject.property1); // weee because this function is executed after myFunc("weee") is executed
    };
    a();
  }
};

alert(myObject.property1); // alerts test
// change the property1 property to something else
myObject.property1 = "zomg";
alert(myObject.property1); // alerts zomg
// change the property1 to weee using myFunc
myObject.myFunc("weee");
alert(myObject.property1); // alerts weee
