Usage

new constructor()

Parameters

constructor

A function followed by any optional parameters in parentheses. The function is

usually the name of the object type (for example, Array, Number, or Object) to be constructed.

Returns

Nothing.

Description

Operator; creates a new, initially anonymous, object and calls the function identified by the

constructor parameter. The new operator passes to the function any optional parameters in

parentheses as well as the newly created object, which is referenced using the keyword

this. The

constructor function can use

this to set the variables of the object.

Example

The following example creates the Book() function and then uses the new operator to create the

objects

book1 and book2:

function Book(name:String, price:Number) {

this.name = name;

this.price = price;

}

var book1 = new Book("Confederacy of Dunces", 19.95);

var book2 = new Book("The Floating Opera", 10.95);

Example

The following example uses the new operator to create an Array object with 18 elements:

var golfCourse_array:Array = new Array(18);
