2D Javascript数组

Question

简单地说,有没有办法使用类似的语法创建一个2D javascript数组？

var newArray = [
    [0, 1, 2],
    [3, 4, 5],
    [6, 7, 8]
]

Answer 1

您可以使用任意的n维数组正是你的建议作为下面的示例中的格式:

<script>
    var newArray = [
        [0, 1, 2],
        [3, 4, 5],
        [6, 7, 8]
    ]
    var newArray3d =
        [[[ 0,  1,  2],[ 3,  4,  5],[ 6,  7,  8]],
         [[10, 11, 12],[13, 14, 15],[16, 17, 18]],
         [[20, 21, 22],[23, 24, 25],[26, 27, 28]]]
    alert(newArray[0]);
    alert(newArray[0][2]);
    alert(newArray3d[0]);
    alert(newArray3d[1][0]);
    alert(newArray3d[1][0][2]);
</script>

警报框按顺序返回:

0,1,2
2
0,1,2,3,4,5,6,7,8
10,11,12
12
