JavaScript：转换对象结构

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;
});

但它只将最后一个密钥对值存储为 newData。那是

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

据我所知，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。

有帮助吗？

您正在分配属性name and data直接到newData而不是将对象作为数组推入其中：

将循环更改为：

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