dataTables how to add sorting image/icon?

本文关键字：排序图像图标添加何添加 dataTables 更新时间：2023-09-26

我使用dataTablesjquery。我想将排序图像添加到列中，图像shd也会在排序时发生变化。也就是说，如果图像显示降序图标，单击时应该会变为升序图标。如何使用dataTablesjquery完成？

我的代码：

$("#rates").dataTable({
         "bPaginate": false,
         "sScrollY":  "250px",
         "bAutoWidth": false,
         "bScrollCollapse": true,
         "fnInitComplete": function() {
                this.css("visibility", "visible");},
                "bLengthChange": false
    });

$(document).ready(function() {
  $("#tblVal").dataTable({
    "bPaginate": false,
    "sScrollY": "250px",
    "bAutoWidth": false,
    "bScrollCollapse": true,
    "fnInitComplete": function() {
      this.css("visibility", "visible");
    },
    "bLengthChange": false
  });
});

          <th>ID</th>
          <th>Name</th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <td>1</td>
          <td>100</td>
          <td>vsa</td>
        </tr>
        <tr>

        </tr>
        <tr>
          <td>3</td>
          <td>102</td>
          <td>nfsa</td>
        </tr>
      </tbody>
    </table>
  </div>
</body>

确保你已经添加了一个合适的js和css文件。试试这个代码，它对我有效

在项目中包含图像文件夹后，调整CSS中的链接以指向图像。在CSS中查找以下代码：

table.dataTable thead .sorting {
  background-image: url("../images/sort_both.png");
}

默认情况下，datatable启用排序。您无法更改数据表中排序图标的颜色，因为这些图标不是图标，而是PNG图像。您需要覆盖那些CSS属性（数据表1.10）

升序

table.dataTable thead .sorting_asc {
    background-image: url("/YourImageFolder/sort_asc.png")
}

降序

table.dataTable thead .sorting_desc {
    background-image: url("/YourImageFolder/sort_desc.png")
}

两者均已禁用

table.dataTable thead .sorting {
    background-image: url("/YourImageFolder/sort_both.png")
}

已禁用升序

table.dataTable thead .sorting_asc_disabled {
    background-image: url("/YourImageFolder/sort_asc_disabled.png")
}

已禁用降序

table.dataTable thead .sorting_desc_disabled {
    background-image: url("/YourImageFolder/sort_desc_disabled.png")
}
