How can I re-create this Javascript array structure in Go?

问题

我有一个JavaScript数组，我该如何在Go中重新创建它？我完全不知道如何创建这么多嵌套的切片或数组。

  1. var goArray = [][]interface{}{
  2.     []interface{}{},
  3.     []interface{}{},
  4.     []interface{}{},
  5.     []interface{}{},
  6.     []interface{}{},
  7.     []interface{}{},
  8.     []interface{}{},
  9.     []interface{}{},
  10.     []interface{}{},
  11.     []interface{}{},
  12. }

JSON输出：

  1. [[[],[],[],[],[]],[[],[],[],[],[]]]

谢谢！

I have this Javascript array, how can I recreate it in Go? I'm completely lost on how to create so many nested slices or arrays.

  1. var jsArray = [
  2.     [
  3.         [],
  4.         [],
  5.         [],
  6.         [],
  7.         [],
  8.     ],
  9.     [
  10.         [],
  11.         [],
  12.         [],
  13.         [],
  14.         []
  15.     ]
  16. ];

JSON output:

  1. [[[],[],[],[],[]],[[],[],[],[],[]]]

Thank you!

假设你要存储在当前的JS数组中的值如下所示：

  1. var jsArray = [
  2.     [
  3.         [1, 2],
  4.         [3, 4],
  5.         [5, 6],
  6.         [7, 8],
  7.         [9, 10]
  8.     ],
  9.     [
  10.         [11, 12],
  11.         [13, 14],
  12.         [15, 16],
  13.         [17, 18],
  14.         [19, 20]
  15.     ]
  16. ];

相同的值可以用Golang切片来存储，如下所示：

  1. goSlice := [][][]int{
  2.     {
  3.         []int{1, 2},
  4.         []int{3, 4},
  5.         []int{5, 6},
  6.         []int{7, 8},
  7.         []int{9, 10},
  8.     },
  9.     {
  10.         []int{11, 12},
  11.         []int{13, 14},
  12.         []int{15, 16},
  13.         []int{17, 18},
  14.         []int{19, 20},
  15.     },
  16. }

上述切片的输出如下所示：

  1. [[[1 2] [3 4] [5 6] [7 8] [9 10]] [[11 12] [13 14] [15 16] [17 18] [19 20]]]

这与jsArray的结构相同。

如果你想使用数组而不是切片，可以这样定义：

  1. goArray := [2][5][2]int{
  2.     {
  3.         [2]int{1, 2},
  4.         [2]int{3, 4},
  5.         [2]int{5, 6},
  6.         [2]int{7, 8},
  7.         [2]int{9, 10},
  8.     },
  9.     {
  10.         [2]int{11, 12},
  11.         [2]int{13, 14},
  12.         [2]int{15, 16},
  13.         [2]int{17, 18},
  14.         [2]int{19, 20},
  15.     },
  16. }

希望这对你有所帮助。

Let's assume that the values that you will store in your current JS array will look like this

  1. var jsArray = [
  2.     [
  3.         [1, 2],
  4.         [3, 4],
  5.         [5, 6],
  6.         [7, 8],
  7.         [9, 10]
  8.     ],
  9.     [
  10.         [11, 12],
  11.         [13, 14],
  12.         [15, 16],
  13.         [17, 18],
  14.         [19, 20]
  15.     ]
  16. ];

The same values can be stored in the Golang slices like this

  1. goSlice := [][][]int{
  2.     {
  3.         []int{1, 2},
  4.         []int{3, 4},
  5.         []int{5, 6},
  6.         []int{7, 8},
  7.         []int{9, 10},
  8.     },
  9.     {
  10.         []int{11, 12},
  11.         []int{13, 14},
  12.         []int{15, 16},
  13.         []int{17, 18},
  14.         []int{19, 20},
  15.     },
  16. }

The output for the above slice looks like this

> [[[1 2] [3 4] [5 6] [7 8] [9 10]] [[11 12] [13 14] [15 16] [17 18] [19
> 20]]]

which is identical to the jsArray structure.

Instead of slices if you want to use array than you can use the define it like this

  1. goArray := [2][5][2]int{
  2.     {
  3.         [2]int{1, 2},
  4.         [2]int{3, 4},
  5.         [2]int{5, 6},
  6.         [2]int{7, 8},
  7.         [2]int{9, 10},
  8.     },
  9.     {
  10.         [2]int{11, 12},
  11.         [2]int{13, 14},
  12.         [2]int{15, 16},
  13.         [2]int{17, 18},
  14.         [2]int{19, 20},
  15.     },
  16. }

Hope this will help you.

尝试这个：

  1. func main() {
  2.     var jsArray [2][5][0]int
  3.     fmt.Println(jsArray)
  4. }

你可以创建嵌套的切片，并从外到内描述它包含的每个切片的长度。

英文:

Try this:

  1. func main() {
  2. 	var jsArray [2][5][0]int
  3. 	fmt.Println(jsArray)
  4. }

You can create your nested slice and describe the length of each slice it contains going from the outside in.
