Add new element to an existing object

Question

I was looking for a way to add new elements to an an existing object like what push does with arrays

I have tried this and it didn\'t work :

var myF         


        

Answer 1

Use this:

myFunction.bookName = 'mybook';
myFunction.bookdesc = 'new';

Or, if you are using jQuery:

$(myFunction).extend({
    bookName:'mybook',
    bookdesc: 'new'
});

The push method is wrong because it belongs to the Array.prototype object.

To create a named object, try this:

var myObj = function(){
    this.property = 'foo';
    this.bar = function(){
    }
}
myObj.prototype.objProp = true;
var newObj = new myObj();
