Bootstrap之表格checkbox复选框全选
效果图:
HTML中无需添加额外的一列来表示复选框,而是由JS完成,所以正常的表格布局就行了:
- <table class="table table-bordered table-hover">
- <thead>
- <tr class="success">
- <th>类别编号</th>
- <th>类别名称</th>
- <th>类别组</th>
- <th>状态</th>
- <th>说明</th>
- </tr>
- </thead>
- <tbody>
- <tr>
- <td>C00001</td>
- <td>机车</td>
- <td>机车</td>
- <td>有效</td>
- <td>机车头</td>
- </tr>
- <tr>
- <td>C00002</td>
- <td>车厢</td>
- <td>机车</td>
- <td>有效</td>
- <td>载客车厢</td>
- </tr>
- </tbody>
- </table>
重点是JS的实现。复选框很小,不容易点到,所以点击每一行也可以选中该行,并用高亮一些CSS样式表示。点击复选框所在单元格也能选中复选框。下面是完整代码和注释说明:
