Question

我有给定JSON格式的API-

{
"1":[
{"project_id":1,"project":"Alamiz City","city":1},
{"project_id":2,"project":"Alamiz Tech City","city":1},
{"project_id":3,"project":"Alamiz Down Town","city":3},
{"project_id":10,"project":"Alamiz Nature","city":2}
],
"3":[
{"project_id":4,"project":"The Tech Sky","city":1},
{"project_id":5,"project":"Alphonso","city":1}
],
"4":[
{"project_id":6,"project":"Royal Tech","city":4},
{"project_id":7,"project":"Future City","city":4}
],
"6":[{"project_id":8,"project":"Zahi Skyline","city":1}],
"2":[{"project_id":9,"project":"Souras City","city":4}]
}

此处JSON对象的Key对应于特定的构建器ID，其值是该构建器完成的所有项目的数组。

我想填充一个由builder_id和相应的构建器项目详细信息组成的表，即Project_id，项目名称和城市ID。

我想从给定的API创建一个单独的数组，然后使用它来填充表。

var project_info= new Array();
$.getJSON('https://interview.switchme.in/js/2019/project_json.php', function(data2) {
   console.log(data2);
   for (var n in data2){
       for (var i=1;i<data2[n].length+1;i++){
           project_info[n][i]=data2[n][i];
       }
   }                     
});

但是我一直收到此错误-未捕获的TypeError：无法设置未定义的属性'1'

我要填充的表的HTML代码是-

<div>
    <h2>Builders Project List Table</h2>
    <table id="proj_tab">

      <tr>
        <th>Builder_id</th>
        <th>Project</th>
        <th>City_id</th>
      </tr>
      <tr>
        <td>1</td>
        <td>Alamiz City</td>
        <td>1</td>
      </tr>
      <tr>
        <td>1</td>
        <td>Alamiz Tech City</td>
        <td>1</td>
      </tr>
</div>

是否有一种使用$.each()来做到这一点的方法，在数组形成之后，我应该使用 $("#proj_tab").html("<tr><td>"+project_info[i]+"</td></tr>"); 还是有更好的方法呢？

使用包含多维JSON对象的API填充表
