  • 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：

    [html] view plain copy
     
    1. <table class="table table-bordered table-hover">  
    2.     <thead>  
    3.         <tr class="success">  
    4.             <th>类别编号</th>  
    5.             <th>类别名称</th>  
    6.             <th>类别组</th>  
    7.             <th>状态</th>  
    8.             <th>说明</th>  
    9.         </tr>  
    10.     </thead>  
    11.     <tbody>  
    12.         <tr>  
    13.             <td>C00001</td>  
    14.             <td>机车</td>  
    15.             <td>机车</td>  
    16.             <td>有效</td>  
    17.             <td>机车头</td>  
    18.         </tr>  
    19.         <tr>  
    20.             <td>C00002</td>  
    21.             <td>车厢</td>  
    22.             <td>机车</td>  
    23.             <td>有效</td>  
    24.             <td>载客车厢</td>  
    25.         </tr>  
    26.     </tbody>  
    27. </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：
