javascript - Angularjs 分割数组

Question

我有一个看起来像这样的数组

    $scope.A = [

          [ "1.31069258855609,103.848649478524", "1.31138534529796,103.848923050526" ],
          [ "1.31213221536436,103.848328363879", "1.31288473199114,103.849575392632" ]

        ];

我想把它做成这样

        $scope.B = [
           [
             [1.31069258855609,103.848649478524], [1.31138534529796,103.848923050526]
           ],
           [
             [1.31213221536436,103.848328363879], [1.31288473199114,103.849575392632]
           ]
         ];

PS:抱歉，如果这不是 split ，我不知道如何解决这个问题

代码:

    var latlngs = $scope.polyLineCord.map(subarr => subarr.map(str => str.split(',').map(Number)))
    console.log(latlngs)

map 外部数组中的每个项目，然后 .map 每个子数组并用逗号split，以及 map > 再次通过 Number 将字符串转换为数字:

const input = [
  ["1.31069258855609,103.848649478524", "1.31138534529796,103.848923050526"],
  ["1.31213221536436,103.848328363879", "1.31288473199114,103.849575392632"]
];
console.log(
  input.map(
    subarr => subarr.map(
      str => str.split(',').map(Number)
    )
  )
);
