Layui批量删除

监听复选框 监听点击事件

• 两个按钮放在<script>中

<script type="text/html" id="toolbarDemo">
  <div class="layui-btn-container demoTable">
    <button class="layui-btn layui-btn-sm" lay-event="add" ><i class="layui-icon layui-icon-add-circle-fine" style="font-size:20px;font-weight:bold"></i> 新增班级</button>
    <button class="layui-btn layui-btn-sm layui-btn-danger" lay-event="batchdel" data-type="getCheckData"><i class="layui-icon layui-icon-delete" style="font-size:20px;"></i> 批量删除</button>
  </div>
</script>

在生成表格的js中 使用了toolbar:"#toolbarDemo",使按钮加载到表格上

• JS实现批量删除(首先开启复选框监听，接着监听点击，active中获取选中数据，通过遍历数据，将班级id存储在delList数组中，通过var strify = JSON.stringify(delList);将数组转为JSON字符串)

//批量删除
     active = {
                getCheckData: function(){ //获取选中数据
                    var checkStatus = table.checkStatus('tableAll')
                    ,checkData = checkStatus.data,
                    delList=[];
                     
                     for (var i = 0; i < checkData.length; i++) {
                        delList.push(checkData[i].classid);
                     }
                     var strify = JSON.stringify(delList);
                    console.log(strify);
                    $.ajax({
                        url:"../../ClassesDeleteBatchServlet",
                        dataType:'json',
                        data:{
                            datas:strify
                        },
                        type:'post',
                        success:function(data){
                            if (data == 0) {
                                layer.msg('删除失败！',{icon:5,offset:"auto",time:2000});//提示框
                            }else{
                                layer.msg('删除成功！',{icon:6,offset:"auto",time:2000});//提示框
                            }
                            
                            setTimeout(function(){
                                location.reload();//重新加载页面表格
                            }, 2100);
                        }
                    })
                }    
             };
        //监听点击
       $('.demoTable .layui-btn').on('click', function(){
             var type = $(this).data('type');
             active[type] ? active[type].call(this) : '';
         });
      //监听表格复选框选择
          table.on('checkbox(table1)', function(obj){
              console.log(obj);
          })
