JavaScript:转换对象结构

Question

我有一个这样的对象:

{
  "A": [ "-4927","8779","-9971","-23767" ],
  "B": [ "-10617","-1456","3131","259" ],
  "C": [ "-5185","1168","21501","18989" ],
  "D": [ "2010","5664","2148","-674" ]
}

我想转换成这样:

[
  {
    name: 'A',
    data: ["-4927","8779","-9971","-23767"]
  }, {
    name: 'B',
    data: ["-10617","-1456","3131","259"]
  }, {
    name: 'C',
    data: ["-5185","1168","21501","18989"]
  }, {
    name: 'D',
    data: ["2010","5664","2148","-674"]
  }
]

我使用了以下方法:

var newData = [];
$.each($.parseJSON(data), function(k, v) {
  newData['name'] = k;
  newData['data'] = v;
});

但它只将最后一个 key 对值存储为 newData。那就是

name: 'D',
data: ["2010","5664","2148","-674"]

我知道它会覆盖以前的数据并仅存储它获得的最后数据。但我无法解决这个问题。

有什么帮助吗？

Answer 1

您将属性 name 和 data 直接分配给 newData 而不是将对象作为数组插入其中:

将循环更改为:

var newData = [];
$.each($.parseJSON(data), function(k, v) {
        const myNewData = {
            name: k,
            data: v
        }
        newData.push(myNewData);
});
