Description
Operator; initializes a new array or multidimensional array with the specified elements (
a0
, and so
on), or accesses elements in an array. The array access operator lets you dynamically set and
retrieve instance, variable, and object names. It also lets you access object properties.
Usage 1: An array is an object whose properties are called elements , which are each identified by a
number called an index . When you create an array, you surround the elements with the array
access ([]) operator (or brackets ). An array can contain elements of various types. For example, the
following array, called
employee
, has three elements; the first is a number and the second two are
strings (inside quotation marks):
var employee:Array = [15, "Barbara", "Jay"];
You can nest brackets to simulate multidimensional arrays. You can nest arrays up to 256 levels
deep. The following code creates an array called
ticTacToe
with three elements; each element is
also an array with three elements:
var ticTacToe:Array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];
// Select Debug > List Variables in test mode
// to see a list of the array elements.
