 操作删除

                
                {volist name='lis' id='v' length="30"}
                

                    
{$v.id}
                    
{$v.name}
                    
{$v.email}
                    
{$v.comment}
                    
{$v.date|substr=###,0,10}
                    
删除
                
                {/volist}
            

        
    

样式css:

/* show页面样式 */
.sh_dv{width: 100%;height: 100%;min-width: 320px;text-align: center;background: #f9f9f9;}

/*反*/

/*正*/
.is .time_left{transform: rotate(-45deg);top:10px;right:30px;}

后端方法：

//条件查询    空值查询
 public function show( $inp = null,$val=null){
        if($inp =='sel'){
            $lis = Db::query("SELECT * FROM msg_information WHERE name = '$val' OR email ='$val' OR date LIKE '$val%'");//查询数据
            $this->assign('lis', $lis);
        }
        if($inp == null || $val == null){
            $lis = Db::query('select * from msg_information ORDER BY date DESC');//查询数据
            $this->assign('lis', $lis);
        }
        return $this->fetch();
    }


//删除单个
    public function del($id){
        $msg = json_encode(['msg'=>'success']);
        $msg2 = json_encode(['msg'=>'false']);
        $list = Db::query('select id from msg_information ');//查询数据
        $locar = array();
        foreach($list as $k =>$v){
            array_push($locar,$v['id']);//本地id集合
        }
        if(!empty($id) && in_array($id,$locar)){//判断传入id不为空 传入id 要在本地id集合中存在
            Db::table('msg_information')->delete($id);//查询数据
            return $msg;
        }else{
            return $msg2;
        }
        return $msg2;
    }

//批量删除
public function delAll(){
   if(request() -> isAjax()){
       $datas = $_POST['id'];
       if(!empty($datas)){
          Db::table('msg_information') -> delete($datas);//批量删除数据
          return json_encode(['msg' => 'success']);
       }else{
          return 'null';
       }
   }
   return json_encode(['msg' => 'false']);
}
