How do you create objects in Javascript?

Answer 1

There are two simple ways to create a new Object in Javascript.

1. Create a direct instance of an object. In this method, we call the native Javascript Object constructor.

myObject = new Object();

myObject.property1 = 'First prop value';

myObject.property2 = 'A different value';

myObject.color = 'blue';

You can get this exact same result with less code by using object literal notation.

myObject = {property1: 'First prop value', property2: 'A different value', color: 'blue'};

Adding a method is also easy. If you have a predefined function, you simply pass the name.

myObject.niftyMethod = ourPreDefMethod;

You can also use anonymous functions here...

myObject.anotherNiftyMethod = function() { alert 'Super cool!'; }

This works fine, but you might find a need for an object constructor, so you can produce objects at will as any given point. In that case, you simply define a function to create an object.

function myObject( property1, property2)

{

this.property1 = property1;

this.property2 = property2;

this.color = null;

//Set a method for changing color

this.changeColor = function(color) {

this.color = color;

}

}

You can also define a function an attach it, same as the other notation.
