可能的重复:
是一种使用 var 在键中创建 JSON 对象的方法吗?

I would like to construct a JSON object in JavaScript by using the value of a (String) variable as the key. But what I got is the name of the variable as the key.

我想通过使用 (String) 变量的值作为键在 JavaScript 中构造一个 JSON 对象。但我得到的是变量名作为键。

example.js:

例子.js:

function constructJson(jsonKey, jsonValue){
   var jsonObj = { "key1":jsonValue, jsonKey:2};
   return jsonObj;
}

The call

电话

constructJson("key2",8);

returns a JSON -> {"key1":8,"jsonKey":2} but I would like to have {"key1":8,"key2":2}.

返回一个 JSON -> {"key1":8,"jsonKey":2} 但我想要 {"key1":8,"key2":2}。

Does anyone know how to achieve this? seems like a simple problem but i cannot find the solution

有谁知道如何实现这一目标?似乎是一个简单的问题,但我找不到解决方案

thx in advance, ronny

提前谢谢,罗尼
