javascript - 如何触发 Yii2 确认对话框

Question

我在 GridView 上有一个自定义的 ActionColumn 并尝试使用 data-confirm 调用 yii.confirm 函数用于删除操作，但未显示对话框。

[
'format'=>'html',
'content'=>function($data) {
    $btn = ButtonDropdown::widget([
    'label' => 'Action',
    'options' => ['class'=>'btn btn-sm btn-primary dropdown-toggle', 'type'=>'button'],
    'dropdown' => [
        'options' => ['class'=>'dropdown-menu action', 'role'=>'menu'],
        'items' => [
            '<li><a href="'.Url::to(['details','id'=>$data->id]) .'"><i class="fa fa-pencil"></i> Details</a></li>',
            '<li><a href="'. Url::to(['edit', 'id' => $data->id]) .'"><i class="fa fa-eye"></i> Edit</a></li>',
            '<li role="presentation" class="divider"></li>',
            '<li><a data-method="post" data-confirm="Are you sure ?" href="'.Url::to(['delete', 'id' => $data->id]).'"><i class="fa fa-trash"></i> Delete</a></li>',                                                
        ],
    ],
]);
return $btn;
},
],

但是当我尝试在没有下拉列表的情况下添加链接时它起作用了

[
'format'=>'html',//raw, html
    'content'=>function($data) {
        $btn ='<a data-method="post" data-confirm="Are you sure ?" href="'.Url::to(['delete', 'id' => $data->id]).'"><i class="fa   fa-trash"></i> Delete</a>';                                                
        return $btn;
    },
],

你可以这样添加一个链接

    <?php echo Html::a(Yii::t('backend', 'Delete'), ['delete', 'id' => $model->id], [
        'class' => 'btn btn-danger',
        'data' => [
            'confirm' => Yii::t('backend', 'Are you sure you want to delete this item?'),
            'method' => 'post',
        ],
    ]) ?>
