这篇文章主要介绍了JavaScript中全选、全不选、反选、无刷新删除、批量删除、即点即改入库（在yii框架中操作）的代码分享,需要的朋友可以参考下
效果展示：
代码实现：
控制器
<?php
namespace app\controllers;
use Yii;
use yii\filters\AccessControl;
use yii\web\Controller;
use yii\filters\VerbFilter;
use app\models\LoginForm;
use app\models\ContactForm;
//use yii\db\ActiveRecord;
use yii\data\Pagination;
use app\models\EcsGoods;
class PageController extends Controller
{
//public $layout=false;
//展示，分页
public function actionList()
{
$query = EcsGoods::find();
$pagination = new Pagination([
'defaultPageSize' => 5,
'totalCount' => $query->count(),
]);
$countries = $query
->offset($pagination->offset)
->limit($pagination->limit)
->all();
return $this->render('list', [
'brr' => $countries,
'pagination' => $pagination,
]);
}
//即点即改
public function actionUpdates()
{
$request = Yii::$app->request;
$id = $request->get('old_id');
$name = $request->get('old_val');
$connection=Yii::$app->db;
$command = $connection->createCommand("update ecs_goods set goods_name='$name' where goods_id='$id'");
$re=$command->execute();
if($re)
{
echo 1;
}
}
//单删
public function actionDel()
{
$request = Yii::$app->request;
$id = $request->get('ids');
$connection=Yii::$app->db;
$command = $connection->createCommand("delete from ecs_goods where goods_id='$id'");
$re=$command->execute();
if($re)
{
echo 1;
}
else
{
echo 0;
}
}
//批删
public function actionAlldel()
{
$request = Yii::$app->request;
$id = $request->get('new_str');
$connection=Yii::$app->db;
$command = $connection->createCommand("delete from ecs_goods where goods_id in($id)");
$re=$command->execute();
if($re)
{
echo 1;
}
else
{
echo 0;
}
}
}
视图层
[html] view plain copy 在CODE上查看代码片派生到我的代码片
