在 Javascript Angular 6 中將字符串轉換為數組

Question

我有一個從console.log(temp)顯示的動態生成的數組：

[{user_id: "test@random.com", status: "Idle"}], 
[{user_id: "whatever@random.com", status: "Busy"}]

我的代碼：

this.scheduleService.getShiftSchedule().subscribe((temp)=>{
  this.api = temp;
  console.log(temp);
})

如何更改我的 Array 的格式，使其像下面的 Array 一樣？

[[{id: 1,content: 'test@random.com'},{id: 2,content: 'Idle'}],
[{id: 1,content: 'whatever@random.com'},{id: 2,content: 'Busy'}]]

Answer 1

您可以通過獲取所需鍵及其id的數組來映射對象。

 var data = [{ user_id: "test@random.com", status: "Idle" }, { user_id: "whatever@random.com", status: "Busy" }], ids = [['user_id', 1], ['status', 2]], result = data.map(o => ids.map(([key, id]) => ({ id, content: o[key] }))); console.log(result);

 .as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 2

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

var newArr = [];
while(arr.length) newArr.push(arr.splice(0,3));

console.log(newArr)

你可以試試這樣

Answer 3

var array = JSON.parse("[" + string + "]");
