1、gridview设置options时增加一个id 这里我们命名grid

 

2、columns增加选项复选框，批量删除必然不可少了复选框操作，这里我们的name值设定为id,方便对数据操作

 

3、页面上我们增加一个批量删除按钮，注意这里我们增加了一个class gridview,方便后面js实现点击效果

 

4、最后一步，写js实现按钮操作，打开你的console看看，我们很轻松的就拿到了选中的行的id，然后这里就可以异步操作数据了。

<script type="text/javascript">

            $(".gridview").on("click", function () {
            var keys = $("#grid").yiiGridView("getSelectedRows");
    
            //post提交
            $.post('<?=Url::to(['message/deleteall']);?>',
            {
              arr_id:keys,
            },

            //返回数据
            function(data,status){
                if (status == "success") {
                    alert("成功删除数据"+data+"条");
                    window.location.reload();//刷新当前页面.
                }else{
                    alert("error");
                    window.location.reload();//刷新当前页面.
                }
            });
});
</script>

 

 MessageController.php中

public function actionDeleteall()
    {    
       return Message::deleteAll(['in','id',Yii::$app->request->post('arr_id')]);
    }

将前端js传来的数组arr_id用系统自带deleteall方法删除，并返回删除的数目
