多维javascript数组中的For循环

Question

var cubes[];

for (i in cubes){
     cubes[i].dimension
     cubes[i].position_x
     ecc..
}

var cubes[][];

cubes[0][0]
cubes[0][1]
cubes[0][2]
cubes[1][0]
cubes[1][1]
cubes[1][2]
cubes[2][0]
ecc...

var cubes[];
var cubes1[];

并分别处理这两个数组。这是更好的解决方案吗？

Answer 1

您可以这样做：

var cubes = [
 [1, 2, 3],
 [4, 5, 6],    
 [7, 8, 9],
];

for(var i = 0; i < cubes.length; i++) {
    var cube = cubes[i];
    for(var j = 0; j < cube.length; j++) {
        display("cube[" + i + "][" + j + "] = " + cube[j]);
    }
}

工作的JSFiddle：

cube[0][0] = 1
cube[0][1] = 2
cube[0][2] = 3
cube[1][0] = 4
cube[1][1] = 5
cube[1][2] = 6
cube[2][0] = 7
cube[2][1] = 8
cube[2][2] = 9
