来自此有效json

{"phone": [

    "@attributes": {
        "type": "cell",
        "ext": ""
    }
}, "[phone]", {
    "@attributes": {

        "ext": ""

推荐答案

从狭义上讲，您需要这样做

In a very narrow sense, you'd need to do this

var jsonObj = JSON.parse(jsonString);

var type = jsonObj.phone[0]['@attributes'].type // "cell"
var phoneNumber = jsonObj.phone[1] // "[phone]"

但是该JSON数据的结构可能会发生变化，因此您不能依赖0/1索引，并且无论如何该结构都是怪异的.就像评论中所说的那样，如果它来自XML，请解析它

But the structure of that JSON data may change, so you can't rely on the 0/1 indexes, and anyway the structure is weird. Like the comments say, if it comes from XML, then parse that instead
