As Moo-Juice said, that is not a valid object. Here is an example of a valid object and how you would access its properties:

var myObj = {
    myString : 'Hello world!',
    myArray : ['red', 'yellow', 'blue'],
    alertString : function() {
        var message = this.myString;
        for (var i = 0; i < this.myArray.length; i++) {
            message += ' ' + this.myArray[i];
        }
        alert(message);
    }

};

myObj.alertString();

// triggers a modal that says 'Hello world! red yellow blue'
