Generate JavaScript Array Code

Generates the code to create a JavaScript array

Array

Object. Lets you create arrays and work with them.

Syntax

To create an Array object:

1. arrayObjectName = new Array([arrayLength])
2. arrayObjectName = new Array([el0, el1, ..., el3])

To use Array objects:

1. arrayObjectName.propertyName
2. arrayObjectName.methodName(parameters)

Parameters

arrayObjectName is either the name of a new object or a property
of an existing object. When using Array properties and methods, arrayObjectName is either the name of an existing Array object or
a property of an existing object.

arrayLength is the initial length of the array. You can access this value using the length property.

elementn is a list of values for the array's elements. When this form is specified, the array is initalized with the specified values as its elements, and the array's length property is set to the number of arguments.

propertyName is one of the properties listed below.

methodName is one of the methods listed below.

Property of

None.

Implemented in

Navigator 3.0

Description

The Array object is a built-in JavaScript object.

You can specify an initial length when you create the array. The following code creates an array of five elements:

billingMethod = new Array(5)

When you create an array, all of its elements are initially null.
The following code creates an array of 25 elements, then assigns values to the first three elements:

musicTypes = new Array(25)
musicTypes[0] = "R&B"
musicTypes[1] = "Blues"
musicTypes[2] = "Jazz"

An array's length increases if you assign a value to an element
higher than the current length of the array. The following code
creates an array of length zero, then assigns a value to element 99.
This changes the length of the array to 100.

colors = new Array()
colors[99] = "midnightblue"

You can construct a dense array of two or more elements starting
with index 0 if you define initial values for all elements. A dense
array is one in which each element has a value. The following code creates a dense array with three elements:

myArray = new Array("Hello", myVar, 3.14159)

In Navigator 2.0, you must index arrays by their ordinal number,
for example document.forms[0]. In Navigator 3.0, you can index arrays by either their ordinal number or their name (if defined).
For example, suppose you define the following array:

myArray = new Array("Wind","Rain","Fire")

You can then refer to the first element of the array as
myArray[0] or myArray["Wind"].

Properties

The Array object has the following properties:


Property	Description
length	Reflects the number of elements in an array
prototype	Lets you add a properties to an Array object.
