我正在尝试使用Pjax和delete按钮创建一个ajaxgridview。删除不需要Ajax。我是Yii2的新手，因此任何帮助都将不胜感激。多谢各位

index.php

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

        'id',
        'title',


        ['class' => 'yii\grid\ActionColumn',
            'buttons' => [
                'delete' => function ($url, $model, $key) {
                    return Html::a('<span class="glyphicon glyphicon-trash"></span>', $url, [
                        'title' => Yii::t('yii', 'Delete'),
                        'data-confirm' => Yii::t('yii', 'Are you sure you want to delete this item?'),
                        'data-method' => 'post',
                    ]);
                },
            ]
        ],
    ],
]); ?>
<?php Pjax::end() ?>
这是控制器中的公共函数actionIndex（）

public function actionDelete($id)
{   
    $model = new Category();
    $this->findModel($id)->delete();
    $dataProvider = new ActiveDataProvider([
        'query' => Category::find(),
    ]);
    return $this->render('index', [
        'dataProvider' => $dataProvider,
        'model' => $model,
    ]);
}

public function actionIndex()
{
    $model = new Category();

    $dataProvider = new ActiveDataProvider([
        'query' => Category::find(),
    ]);

    if ($model->load(Yii::$app->request->post()) && $model->save())
    {
        $model = new Category();
    }
    return $this->render('index', [
        'dataProvider' => $dataProvider,
        'model' => $model,
    ]);
}
首先添加
Pjax:：end（）在gridview的末尾
然后指定：


    'delete' => function ($url, $model, $key)
    {
         return Html::a('<span class="glyphicon glyphicon-trash"></span>', $url, [
                'title' => Yii::t('yii', 'Delete'),
                'data-confirm' => Yii::t('yii', 'Are you sure you want to delete this item?'),
                'data-method' => 'post',
      ]);
   },



data-method
和
data-confirm
不允许您通过pjax创建ajax请求，您应该实现自己的确认对话框并删除POST-verb过滤器，或者您可以通过确认对话框和指定http方法实现自己的ajax插件


另外，我认为，肯定有办法通过确认对话框扩展pjax插件，但Yi2默认不提供此功能。
请尝试修改actionDelete（）

因为Controller->redirect（）无法禁用ajaxCheck，所以需要使用Response来执行此操作


我在中创建了相同的问题。
不要设置
数据方法
和
数据确认
，因为
Pjax
不支持这一点

删除这两个后仍然不工作，是的，因为您的控制器的下面代码不允许Pjax get请求


return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [
                    'delete' => ['post'], // **remove this**
                ],
            ],
        ];


您需要使用Pjax Post方法
将此应用到Pjax中


'clientOptions' => ['method' => 'POST']



首先删除“数据确认”和“数据方法”=>“发布”。pjax不起作用了。
如果您想实现一个带有操作按钮的确认框，下面是我将在我的view index.php文件中执行的操作


<?php  Pjax::begin(['id' => 'pjax-container']); 
echo GridView::widget([
    'test' => function ($url, $dataProvider) {
    return Html::a('Test',
        ['/site/test'],
        ['title'=>'Test',
         'onclick' => "if (confirm('ok?')) {
              $.ajax('/site/test', {
                  type: 'POST'
              }).done(function(data) {
                   $.pjax.reload({container: '#pjax-container'});
              });
          }
          return false;
          ",
          ]);
        },
    ])
Pjax::end();
?>


这样你也会得到确认等。如果需要，您可以使用其他第三方引导确认等，并且可以正常工作。
可以这样使用：


<?php Pjax::begin(['id' => 'model-grid']);
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    //...
    [
            'class' => 'yii\grid\ActionColumn',
            'template' => '{update} {delete}',
            'contentOptions' => ['class' => 'action-column'],
            'buttons' => [
                'delete' => function ($url, $model, $key) {
                    return Html::a('<span class="glyphicon glyphicon-trash"></span>', $url, [
                        'title' => 'Delete',
                        'data-pjax' => '#model-grid',
                    ]);
                },
            ],
        ],
    ],
]); 
Pjax::end(); ?>


鉴于：


'delete' => function ($url, $model, $key) {
  $options = [
    'title' => Yii::t('common', 'delete'),
    'aria-label' => Yii::t('common', 'delete'),
    'data-pjax' => 'w0',//id
    'data-confirm' => Yii::t('yii', 'Are you sure you want to delete this item?'),
    'data-method' => 'post',
    'class' => 'btn btn-xs btn-danger'
  ];
  return Html:: a('<i class="fa fa-fw fa-trash"></i>', [
    'delete',
    'id' => $model -> id
  ], $options);
}



您是否指定了Pjax:：end（）；在您上面的代码中，gridview之后缺少了它。我的解决方案就像一个符咒……我个人在我的项目中使用过。请更改控制器代码，然后检查。检查，但仍然相同，我认为是因为“return$this->redirect（['index']）；”在控制器中，我有同样的问题，delete发送一个正常的请求，不是AJAX请求。data-confirm当前禁用pjax请求。请参阅此问题，因此如果在GitHub上对功能请求使用data confirm？+1，则无法使用pjax在gridview中删除！此方法也适用于数据确认&data method=“post”

public function actionTest()
{

    if (!Yii::$app->request->isAjax) {
        return $this->redirect(['index']);
    }
}



<?php Pjax::begin(['id' => 'model-grid']);
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    //...
    [
            'class' => 'yii\grid\ActionColumn',
            'template' => '{update} {delete}',
            'contentOptions' => ['class' => 'action-column'],
            'buttons' => [
                'delete' => function ($url, $model, $key) {
                    return Html::a('<span class="glyphicon glyphicon-trash"></span>', $url, [
                        'title' => 'Delete',
                        'data-pjax' => '#model-grid',
                    ]);
                },
            ],
        ],
    ],
]); 
Pjax::end(); ?>



public function actionDelete($id)
{
    $this->findModel($id)->delete();
    $searchModel = new ModelSearch();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}



'delete' => function ($url, $model, $key) {
  $options = [
    'title' => Yii::t('common', 'delete'),
    'aria-label' => Yii::t('common', 'delete'),
    'data-pjax' => 'w0',//id
    'data-confirm' => Yii::t('yii', 'Are you sure you want to delete this item?'),
    'data-method' => 'post',
    'class' => 'btn btn-xs btn-danger'
  ];
  return Html:: a('<i class="fa fa-fw fa-trash"></i>', [
    'delete',
    'id' => $model -> id
  ], $options);
}



$this -> findModel($id) -> delete ();
$searchModel = new AdminSearch();
//get the referer url
$url = Yii::$app -> request -> referrer;
$arr = parse_url($url, PHP_URL_QUERY);
parse_str($arr, $output);//get the $_GET array
$dataProvider = $searchModel -> search($output);
return $this -> render('index', [
  'searchModel' => $searchModel,
  'dataProvider' => $dataProvider,
]);
