推荐答案

一维数组将是：

var myArr = new Array();
myArr[0] = "Hi";
myArr[1] = "there";
myArr[2] = "dude";

alert(myArr[1]);    // Alerts 'there'

二维数组将是：

var myArr = new Array();
myArr[0] = new Array("Val", "Va");
myArr[1] = new Array("Val", "yo");
myArr[2] = new Array("Val", "Val");

alert(myArr[1][1]); // Alerts 'yo'

3D数组更复杂，你应该评估你的建议用途因为它在网络中的范围有限。使用1D或2D阵列可以解决99％的问题。但3D阵列将是：

A 3D array is more complicated, and you should evaluate your proposed use of it as it has a limited scope within the web. 99% of problems can be solved with 1D or 2D arrays. But a 3D array would be:

var myArr = new Array();
myArr[0] = new Array();
myArr[0][0] = new Array()
myArr[0][0][0] = "Howdy";
myArr[0][0][1] = "pardner";

alert(myArr[0][0][1]); // Alerts 'pardner'
