获取JSON中键的索引 [英] Get index of a key in json

问题描述

我有一个像这样的json:

I have a json like so:

json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }

现在，我想知道一个键的索引，在json中说"key2"-为1.有没有办法?

Now, I want to know the index of a key, say "key2" in json - which is 1. Is there a way?

推荐答案

为时已晚，但它可能既简单又有用

Its too late, but it may be simple and useful

var json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" };
var keytoFind = "key2";
var index = Object.keys(json).indexOf(keytoFind);
alert(index);
