javascript - 如何绑定(bind)复选框以从 javascript 对象获取正确的数据？

Question

我有一个对象，其中包含一些数据，我希望在单击复选框时访问这些数据。

以下是我拥有的复选框的示例。

  <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">

因此，当我单击复选框时，我想访问相应的对象并将“名称”和“图像”分配给变量，以便稍后将它们添加到我的页面中。我会通过执行类似 var foo = docs.dealership.dealership1.name 的操作来做到这一点，但我遇到了问题，因为我读到我不能使用 docs.var1.var2.name 这样的变量

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"
                },

            }

        }

Answer 1

<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;
    });
