Javascript将数组拆分为多个数组

Question

我在使用 javascript 将数组拆分为多数组时遇到了一些麻烦。例如，我有这个数组:

[0] => object
   [0] => object
      [0] => The Letter P
      [1] => 5.5
   [1] => object
      [0] => 5
      [1] => 1.1
      [2] => 5
      [3] => 1
      [4] => 1
   [2] => object
      [0] => 5
      [1] => 1.1.1
      [2] => 1.1.1
      [3] => 1.1.1
      [4] => 3

我想做的是拆分周期，并创建一个更深的数组，如下所示:

[0] => object
    [0] => object
       [0] => The Letter P
       [1] => object
          [0] => 5
          [1] => 5
    [1] => object
       [0] => 5
       [1] => object
          [0] => 1
          [1] => 1
       [2] => 5
       [3] => 1
       [4] => 1
    [2] => object
       [0] => 5
       [1] => object
          [0] => 1
          [1] => 1
          [2] => 1
       [2] => object
          [0] => 1
          [1] => 1
          [2] => 1
       [3] => object
          [0] => 1
          [1] => 1
          [2] => 1
       [4] => 3

我已经尝试了几乎所有我能想到的方法，但似乎找不到有效的代码 :( 请帮助我 :(

这应该可行

function dotsToArr(arr) {
    for(var x = 0; x < arr.length; x++) {
        if(typeof(arr[x]) != "object") {
            var parts =  (arr[x]+"").split(".");
            if(parts.length > 1) {
                arr[x] = parts;
            }

            continue;
        }

        dotsToArr(arr[x]);
    }
}
