如何绑定复选框以从javascript对象获取正确的数据？

我有一个对象，其中包含一些我希望在单击复选框时被访问的数据

以下是我的复选框示例

  <input type="checkbox" id="dealership1" name="dealership1">
  <input type="checkbox" id="dealership2" name="dealership2">
  <input type="checkbox" id="dealership3" name="dealership3">

  <input type="checkbox" id="state1" name="state1">
  <input type="checkbox" id="state2" name="state2">
  <input type="checkbox" id="state3" name="state3">

$（'input'）.change（函数（）{
var type=$（this.attr（'data-id'）；
var name=$（this.attr（'name'）；
var n=单据[类型][名称]。名称；
});

请阅读如何创建带括号的文档[var1][var2]。名称可能重复的

var docs = {

            'dealership': {

                dealership1: {
                    "name" : "Trade-In Appraisal",
                    "image": "http://unsplash.it/100"
                },
                dealership2: {
                    "name" : "Service Details",
                    "image": "http://unsplash.it/200"
                },
                dealership3: {
                    "name" : "Referral Form",
                    "image": "http://unsplash.it/300"
                },

            },

            'state': {

                state1: {
                    "name" : "Application for Title",
                    "image": "http://unsplash.it/400"
                },
                state2: {
                    "name" : "Bill of Sale",
                    "image": "http://unsplash.it/500"
                },
                state3: {
                    "name" : "County of Title Issuance",
                    "image": "http://unsplash.it/600"
                },

            }

        }

<input type="checkbox" data-id="dealership" name="dealership1">
<input type="checkbox" data-id="dealership" name="dealership2">
<input type="checkbox" data-id="dealership" name="dealership3">

<input type="checkbox" data-id="state" name="state1">
<input type="checkbox" data-id="state" name="state2">
<input type="checkbox" data-id="state" name="state3">



$('input').change(function() {
      var type = $(this).attr('data-id');
      var name = $(this).attr('name');

      var n = docs[type][name].name;
    });
