如何解析和输出具有动态值的JSON对象? [英] How to parse and output JSON object with dynamic values?

问题描述

我需要输出如下的JSON对象:

I need to output JSON object, that looks like:

{
    "dynamicvaluenumberone":3,
    "dynamicvaluenumbertwo":7
}

在某些情况下，看起来像: dynamicvaluenumberone (3), dynamicvaluenumbertwo(7)

In something, that looks like: dynamicvaluenumberone (3), dynamicvaluenumbertwo(7)

我找到了一些带有静态值或使用jQuery解析JSON的文章.我不想使用任何框架来完成此简单任务.

I've found some articles with static values or parsing JSON with jQuery. I don't want to use any framework to do this simple task.

推荐答案

您是否尝试过 JSON.parse ?

Have you tried JSON.parse?

var json = '{"dynamicvaluenumberone":3, "dynamicvaluenumbertwo":7}';
var obj = JSON.parse(json);

要访问动态键，可以使用 for...in :

For accessing dynamic keys, you can loop over the keys using for...in:

for(var i in obj) {
    console.log(i + " (" + obj[i] + ")");
}

更新:根据您需要支持的浏览器，JSON库也可以在此处使用: http://www.json.org/js.html

Update: Depending on the browsers you need to support, the JSON library is also available here: http://www.json.org/js.html
