thinkphp3.1 二级联动菜单

部门和责任人联动

ajax交互:点击获取部门id,传给后端，后端根据id查到数据，return，js再给select赋值

                        <select name="bm" id="bm">
                           <volist name="branch" id="vo">
                               <option value="{$vo.b_id}">{$vo.branch_name}</option>
                           </volist>
                       </select>

                      <select name="zrr" id="zrr">
                          <volist name="fusers" id="vo">
                              <option value="{$vo.user_nicename}">{$vo.user_nicename}</option>
                          </volist>
                      </select>
