在yii2中带有确认的删除按钮

Question

这个view.php在Yii2中用CRUD生成，但是删除按钮不确认窗口。

但是在用Yii2中的CRUD生成的index.php中，删除的确认窗口起作用了。在index.php中

<p> 
    <?= Html::a('Edit', ['update', 'id' => $model->id], ['class' => 'btn btn-primary']) ?> 
    <?= Html::a('Delete', ['delete', 'id' => $model->id], [ 
      'class' => 'btn btn-danger', 
      'data' => [ 
       'confirm' => 'Are you sure you want to delete this item?', 
       'method' => 'post', 
      ], 
    ]) ?> 
    <?= Html::a('Back','index', ['class' => 'btn btn-warning']) ?> 
</p> 

删除按钮：

<a href="var/delete?id=2" title="Delete" aria-label="Delete" data-pjax="0" data-confirm="Are you sure you want to delete this item?" data-method="post"><span class="glyphicon glyphicon-trash"></span></a> 

删除按钮在view.php：

<a class="btn btn-danger" href="var/delete?id=2" data-confirm="Are you sure you want to delete this item?" data-method="post">Delete</a>

的section about yii.js仍在进行中。

要获得默认的确认支持，您应该注册yii.js。

使用yii\web\YiiAsset

use yii\web\YiiAsset; 
YiiAsset::register($this); 

或registering script files（不推荐，只是举例）

$this->registerJsFile('@yii/assets/yii.js', ['depends' => [\yii\web\JqueryAsset::className()]]);
