将JSON对象转换为JS键/值对Array [英] converting JSON object to JS Key/value pairs Array

问题描述

我有一个要求，我有一个JSON对象应该转换为键/值对数组。

I have a requirement, where i am having a JSON object which should be converted to Key/value pairs array.

JSON：

Object {id: "1213115", transac_status: "Y", trans_id: "601427"....}

这应该转换为JS数组，如下所示：
JS Array：

This should be converted to JS array like below: JS Array:

var transData = [{ id: "1213115", transac_status: "Y", trans_id: 601427".... ];

我尝试使用以下脚本进行转换。

I tried the below script for the conversion.

var transData = $.map(Object , function (e2, e1) {
    return [[e2, e1]];
});

数组未按预期转换，而是具有以下内容： -

The array has not been converted as expected, Instead it has the following :-

Array[2]
, 
Array[2]
, 
Array[2]
, 
Array[2]

.....等

推荐答案

我认为你的代码没有任何问题。你说，那个你想要生成一个具有键值对的数组，你实际上是这样做的：

There is nothing wrong with your code I think. You said, that you want to produce an array with key-value pairs, which you actually do:

Array[2] , Array[2] , Array[2] , Array[2] 

这只是 console.log 生成。如果你仔细观察阵列，你会看到它实际上是：

This is just the output that console.log produces. If you look closer at your array you'll see, that it actually is:

[["1213115", "id"], ["Y", "transac_status"], ["601427", "trans_id"]]

考虑一下，你可能想要切换你的键/值对，如下所示：

Thinking about it, you probably might want to switch your key/value pair, like this:

var transData = $.map(Object , function (value, key) {
    return [[key, value]];
});

我重命名了函数参数以使事情变得更清晰。

I renamed the function arguments to make things a little clearer.

输出为：

[["id", "1213115"], ["transac_status", "Y"], ["trans_id, "601427"]]

Tipp：如果你在工作一个浏览器，你可以用这一行输出整个数组，这给你一个很好的表格输出：

Tipp: If you are working in a browser, you can just output the whole array with this line, which gives you a nice table-form output:

console.table(transData);

这就是你要找的东西吗？希望有所帮助。
