javascript - 将 JSON 转换为关联数组

Question

我想将 JSON 响应转换为关联数组，但看起来我做不对。

这是我的 JSON 示例响应:

{
   "response":[
  {
     "id":100,
     "certificate":{
        "id":1,
        "title":"Lorem ipsum dolor sit amet, consectetur adipiscing elit."

     },
     "created_at":"2013-12-02T15:20:08.233Z"

  },
  {
     "id":101,
     "certificate":{
        "id":2,
        "title":"Aenean facilisis, nisl vitae pulvinar varius."
     },
     "created_at":"2013-12-02T15:20:08.240Z"

  }
 ],
"count":2
}

这是我目前尝试过的:

    var len = obj.response.length;
    var rData = [];
    var gcData = [];


    for(var i = 0; i < len; i++){

        rData[i] = $.map(obj.response[i], function(value, index) {

            if(typeof value=="object"){
                gcData = $.map(value, function(value1, index) {
                    return [value1];
                });

                return gcData;

            }else{              
                return [value];
            }
        });     

    }

我的预期输出:

rData = [
    100 : [
           id: ["100"],
           certificate: [
              id: ["1"],
              title: ["Lorem ipsum dolor sit amet, consectetur adipiscing elit."]
           ],
           created_at: ["2013-12-02T15:20:08.240Z"]   

         ]
    101 : [
           id: ["101"],
           certificate: [
              id: ["2"],
              title: ["Aenean facilisis, nisl vitae pulvinar varius."]
           ],
           created_at: ["2013-12-02T15:20:08.240Z"]   

         ]

]

请帮忙。谢谢。

I just want to group it by keys something like I have in expected output

您似乎想创建一个 id -> object 映射。为此，您只需遍历数组，将每个对象的 id 属性作为属性名称，并将对象(数组的元素)分配给 map 的该属性。

例子:

var map = {};
var response = obj.response;

for (var i = 0, l = response.length; i < l; i++) {
    map[response[i].id] = response[i];
}

console.log(map);

数组中的每个对象都已经处于您想要的结构中。输出是

{
    "100": {
        "id": 100,
        "certificate": {
            "id": 1,
            "title": "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
        },
        "created_at": "2013-12-02T15:20:08.233Z"
    },
    "101": {
        "id": 101,
        "certificate": {
            "id": 2,
            "title": "Aenean facilisis, nisl vitae pulvinar varius."
        },
        "created_at": "2013-12-02T15:20:08.240Z" 
    }
}
