javascript - 从js数组中删除双引号

Question

我有这种类型的数组

[[["80.529299450867271,7.3884550841172976"],["80.528953669541707,7.3875715810979612"],["80.528714422417153,7.3867339810469588"]]]

我想把它变成

[[[80.529299450867271,7.3884550841172976],[80.528953669541707,7.3875715810979612],[80.528714422417153,7.3867339810469588]]]

这是我尝试过的

z = a.map(function(o) {
  var d = o.split(/(],)/g).map(function(b) {
    console.log();
    return b;
});

Answer 1

答案:

您可以映射内部数组并拆分字符串，然后将返回数组的成员转换为数字。

arr[0] = arr[0].map(([v]) => v.split(",").map(Number));

工作示例:

let arr = [[["80.529299450867271,7.3884550841172976"],["80.528953669541707,7.3875715810979612"],["80.528714422417153,7.3867339810469588"]]];

arr[0] = arr[0].map(([v]) => v.split(",").map(Number));

console.log(arr);
