想要使用Javascript将一个JSON对象拆分为多个JSON对象

问题描述

我有如下JSON响应，

I have a JSON response like below,

[{label: "8", value: "1", value2: "0", value3: "0"},{label: "9", value: "7", value2: "2", value3: "6"},{label: "10", value: "12", value2: "1", value3: "0"},…]

现在我要拆分每个密钥分为4个JSON对象，如下所示。

Now I want to split it into 4 JSON objects for each key, like below.

[{label: "8"},{label: "9"},{label: "10"},…]
[{value: "1"},{value: "7"},{value: "12"},…]
[{value2: "0"},{value2: "2"},{value2: "1"},…] and more

我尝试了下面的事情，但没有成功。

I tried below things but wasn't successful.

试试1：

var o2 = { uhash: o.uhash };
delete o.uhash;

试试2：

使用for循环到得到每一对，array.push和JSON.stringigy（）方法。

Using for loop to get each pair, array.push and JSON.stringigy() method.

我想要的是使用来自数据库的JSON响应创建堆叠的fusioncharts

All I want to is create a stacked fusioncharts using the JSON response from database

推荐答案

您可以创建一个返回所需数组的函数：
然后，您可以映射并在JSON中的属性上调用它：

You could make a function that returns the array you want:You could then map through and call this on the properties in your JSON:

function makeArray(value) {
  return j.map(function(a) {
    return {[value]: a[value]};
  });
}

var labels = makeArray('label');
