Question
Simply put, is there a way to create a 2D javascript array using similar syntax to this?
var newArray = [
[0, 1, 2],
[3, 4, 5],
[6, 7, 8]
]
Solution
You can create any n-dimensional arrays using exactly the format you suggest as in the following sample:
<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>
The alert boxes return, in sequence:
0,1,2
2
0,1,2,3,4,5,6,7,8
10,11,12
12
OTHER TIPS
Yes. This works fine:
<script>
var newArray = [
[0, 1, 2],
[3, 4, 5],
[6, 7, 8]
]
alert(newArray[0][2]);
</script>
Tested and working in FF3, Opera 9, IE6, and Chrome.
