选中数据，点击头工具栏的按钮进行删除

获取选中的数据，将数据放到数组中

    var delete1 = checkStatus.data;
    var ids = [];
    for (var i = 0;i<delete1.length ;i++){
        ids.push(delete1[i].id)
    }
    console.log(ids)

用Ajax将要删除的id传送到后台

    case 'del':
        var  layer = layui.layer;
        //layer.msg('删除');
        //将删除的id的数组传送到后台
        $.ajax({
            type:"get",
            url:"/videos/del",
            data:{
                ids:ids
            },
            traditional:true,//如果传送的数据是数组，则需要
            dataType:"json",
        })
        break;

控制层Controller

    //del
    @RequestMapping("/del")
    @ResponseBody
    public Result del(String[] ids){
        Result result = new Result();
        System.out.println(ids);
        try {
            for (String id:ids){
                videoService.deleteByPrimaryKey(id);
            }
            result.setMessage("ok");
            result.setStatus(0);
        }catch (Exception e){
            e.printStackTrace();
            result.setMessage("error");
        }
        return result;
    }

业务层Service

Service.java

    int deleteByPrimaryKey(String id);

ServiceImpl.java

    @Override
    public int deleteByPrimaryKey(String id) {
        return videoMapper.deleteByPrimaryKey(id);
    }

将结果反馈给前端

    success:function (res) {
        if (res.message = "ok"){
            layer.alert(res.message,{icon:2},function (index){
                layer.close(index)
                tableIns.reload()
                //再刷新之前弹出窗口确认
                //window.location.reload()
            })
        }
    }
