基于php(Thinkphp)+jquery 实现ajax多选反选不选删除数据功能

//thinkphp循环显示把data里fid赋予多选框<volist name="data" id="vo"><tr>   <td><input type="checkbox" value="{$vo.fid}"/></td>//可在后面加td输入参数  </tr></volist><tr><th width="80"><input type="checkbox" id="all"/>全选</th><th width="80"><input type="button" value="全选" class="btn" id="selectAll" /></th><th width="80"><input type="button" value="全不选" class="btn" id="unSelect" /></th><th><input type="button" value="反选" class="btn" id="reverse" /></th> <th width="180"> <a href="javascript:void(0);" rel="external nofollow" onclick="del()"    //多选    $("#all").click(function(){       if(this.checked){           $("#list :checkbox").attr("checked", true);        }else{           $("#list :checkbox").attr("checked", false);       }       });    //当点到全选按钮    $("#selectAll").click(function () {       $("#list :checkbox,#all").attr("checked", true);      });    //全不选    $("#unSelect").click(function () {        $("#list :checkbox,#all").attr("checked", false);      });    //反选    $("#reverse").click(function () {        $("#list :checkbox").each(function () {          $(this).attr("checked", !$(this).attr("checked"));        });       allCheck();     });    //删除    function del(){      var valArr = new Array;      $("#list :checkbox[checked]").each(function(i){         valArr[i] = $(this).val();       });      var vals = valArr.join(',');//数组转换以逗号隔开的字符串       if (valArr.length == 0) {        alert('请选择要删除的选项');      }else{        if (confirm("确定删除？删除后将无法恢复。")){          var data={name:vals};          $.ajax({            type: "post",            url: "{:U('College/School/faculty_del')}",//url为tp方法（控制器/方法）            data:data,            success: function(json) {             var obj = eval('(' + json + ')');//返回回来的json转化为js对象              if (parseInt(obj.counts) > 0) {                alert(obj.des);                location.reload();               } else {                alert(obj.des);               }              },            error: function(XMLHttpRequest, textStatus) {               alert("页面请求错误，请检查重试或联系管理员！/n" + textStatus);             }           });        }      }    }</script>
