yii2 PJAX重新加载后如何显示模式？

use yii\web\View;

public function actionYourAction()
{
    // your code here

    // Register the JavaScript code
    $js = <<< JS
        $(document).on('pjax:success', function() {
            $('#your-modal').modal('show');
        });
JS;
    $this->getView()->registerJs($js, View::POS_READY);

    // your code here
}

<div id="your-modal" class="modal fade" tabindex="-1" role="dialog">
    <!-- modal content here -->
</div>
