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：
