基于php(Thinkphp)+jquery 实现ajax多选，反选，不选 删除数据 生手学习向

 1 //thinkphp循环显示把data里fid赋予多选框
 2 <volist name="data" id="vo">
 3 <tr>
 4       <td><input type="checkbox" value="{$vo.fid}"/></td>//可在后面加td输入参数    
 5 </tr>
 6 </volist>
 7 <tr>
 8 <th width="80"><input type="checkbox" id="all"/>全选</th>
 9 <th width="80"><input type="button" value="全选" class="btn" id="selectAll" /></th>
10 <th width="80"><input type="button" value="全不选" class="btn" id="unSelect" /></th>
11 <th><input type="button" value="反选" class="btn" id="reverse" /></th> 
12 <th width="180">
13   <a href="javascript:void(0);" onclick="del()" title="删除选定数据">删除</a>
14 </th> 
15 </tr>
