这里有新鲜出炉的Javascript教程,程序狗速度看过来!

JavaScript客户端脚本语言

Javascript 是一种由Netscape的LiveScript发展而来的原型化继承的基于对象的动态类型的区分大小写的客户端脚本语言,主要目的是为了解决服务器端语言,比如Perl,遗留的速度问题,为客户提供更流畅的浏览效果。


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
