Yii2 Pjax GridView action buttons issue

问题:

I am trying to make an Ajax GridView using Pjax. Everything is working fine except the view, update and delete buttons are not AJAX. The code is:

<?php yii\widgets\Pjax::begin(['id' => 'demo']); ?>
<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],

        'id',
        'name',


        ['class' => 'yii\grid\ActionColumn'],
    ],

]); ?>
<?php yii\widgets\Pjax::end(); ?>

The problem is that the links for delete, view and update have the attribute data-pjax=0 which disables AJAX functionality. I cant find out how to set it too data-pjax=1.

You must do like below:

For Delete Action

1- Change your delete action like below:

public function actionDelete($id) {
    $this->findModel($id)->delete();
    if (Yii::$app->getRequest()->isAjax) {
        $dataProvider = new ActiveDataProvider([
            'query' => ModelName::find(),
            'sort' => false
        ]);
        return $this->renderPartial('index', [
                    'dataProvider' => $dataProvider
        ]);
    }
    return $this->redirect(['index']);
}

2- In your grid view:

['class' => 'yii\grid\ActionColumn',
        'buttons' => [
            'delete' => function ($url, $model) {
                return Html::a('<span class="glyphicon glyphicon-trash"></span>', $url, [
                            'title' => Yii::t('yii', 'Delete'),
                            'data-pjax'=>'w0',
                ]);
            }
        ]
    ],

Now, it works with Pjax.

Notes

• My code in deleteAction() may decrease performance. You can write your own.
• w0 usually is the default id of PJax. You can add an id to PJax and write it there instead.
• This is the same for Update and View, But you need to change the way you show your update and view views.
• This is highly recommended to take a look at Yii2's official PJax document: http://www.yiiframework.com/doc-2.0/yii-widgets-pjax.html
