Javascript Object Method

Object Methods

In addition to properties, objects can have methods. An object’s method is a function it can perform. Let’s take a look at this example. For this one, let’s create a Circle object. First, we’re going to have to define our functions, and then make them methods of our Circle object. Let’s define our Circle() constructor and a Circle object or two:

function Circle(radius){  

  this.radius = radius;  

}  

  

var bigCircle = new Circle(100);  

var smallCircle = new Circle(2);

Javascript Object

An object is a collection of properties. These properties can either be primitive data types, other objects, or functions (which in this case are called methods, but more on this later). A constructor function (or simply, constructor) is a function used to create an object – this too we’ll discuss in detail later. JavaScript comes with many built-in objects, such as the Array, Image, and Date objects. Many of you are familiar with Image objects from creating those ever-so-cute rollover effects. Well, when you use the code

var Image1 = new Image();  

Image1.src = "xyz.gif";

Make Object In javascript

Defining Methods and Properties

function jobj(){

    this.nm= 'an object';

    this.do = function(){

        alert('my name ' + this.nm);

    };

};
