javascript - 响应式 jQuery 数据表无法获取一行的详细信息

Question

我正在使用插件 jQuery DataTables使用响应式插件，这样我就可以根据浏览器大小动态显示和隐藏列。

我有一个名为 Actions 的列，用户可以使用它来编辑记录，当按下此列中包含的铅笔时，我搜索被单击的 id元素。

此机制仅在表格未处于响应式模式时有效，事实上，当表格处于响应式且我展开其他列时:

如果我点击铅笔我会得到:

Cannot read property 'id' of undefined

因为插件无法找到被点击元素所在的行。

我创建了一个片段，一个 JSFIDDLE

$(document).ready(function() {
  var table = $('#example').DataTable({
    "columns": [{
        data: 'name'
      },
      {
        data: 'position'
      },
      {
        data: 'office'
      },
      {
        data: 'age'
      },
      {
        data: 'salary'
      },
      {
        data: null,
        render: function(data, type, row) {
          return '<a href="javascript:void(0)" data="' + data.id + '" class="btn btn-link btn-warning btn-icon btn-sm edit"><i class="fas fa-pencil-alt"></i></a>';
        }
      }
    ],
    responsive: true
  });

  var users = [{
      id: 1,
      name: "Penny",
      position: "waitress",
      office: "none",
      age: "25",
      salary: "1550$"
    },
    {
      id: 2,
      name: "Sheldon",
      position: "physical",
      office: "university",
      age: "39",
      salary: "8435$"
    },
    {
      id: 3,
      name: "Leonard",
      position: "physical",
      office: "university",
      age: "35",
      salary: "7842$"
    },
  ];

  $('#example').DataTable().clear().draw();
  $('#example').DataTable().rows.add(users);
  $('#example').DataTable().draw();

  $('#example').on('click', '.edit', function(element) {

    var tr = $(element.target).closest('tr');
    var data = table.row(tr).data();
    console.log(data.id);
  });
});

      <th>Salary</th>
      <th class="sorting_desc_disabled sorting_asc_disabled">Action</th>
    </tr>
  </thead>

  <tfoot>
    <tr>
      <th>Name</th>
      <th>Position</th>
      <th>Office</th>
      <th>Age</th>
      <th>Salary</th>
      <th class="sorting_desc_disabled sorting_asc_disabled">Action</th>
    </tr>
  </tfoot>

  <tbody>
  </tbody>
</table>

我做错了什么吗？或者这是一个错误？有办法解决这个问题吗？

提前致谢。

根据评论讨论，我发布了它

$(document).ready(function() {
  var table = $('#example').DataTable({
  "columns": [{
    data: 'name'
  },
  {
    data: 'position'
  },
  {
    data: 'office'
  },
  {
    data: 'age'
  },
  {
    data: 'salary'
  },
  {
    data: null,
    render: function(data, type, row) {
      return '<a href="javascript:void(0)" class="btn btn-link btn-warning btn-icon btn-sm "><i class="fas fa-pencil-alt edit" data-id="' + data.id + '" ></i></a>'; // same class in i element removed it from a element
    }
  }
],
responsive: true
});

var users = [{
  id: 1,
  name: "Penny",
  position: "waitress",
  office: "none",
  age: "25",
  salary: "1550$"
},
{
  id: 2,
  name: "Sheldon",
  position: "physical",
  office: "university",
  age: "39",
  salary: "8435$"
},
{
  id: 3,
  name: "Leonard",
  position: "physical",
  office: "university",
  age: "35",
  salary: "7842$"
},
];

$('#example').DataTable().clear().draw();
$('#example').DataTable().rows.add(users);
$('#example').DataTable().draw();

$(document).on('click', '.edit', function(element) {

console.log($(this).data('id')); //direct get the value
});
 });
