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 myFunction = {     Author: 'my name ',     date: '15-12-2012',     doSomething: function(){         alert("helloworld")     } }; myFunction.push({     bookName:'mybook',     bookdesc: 'new' }); console.log(myFunction); 

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();
