如何让ajax更新和ajax验证在Yii2中协同工作？

<?php
use yii\widgets\ActiveForm;
use yii\helpers\Url;

$form = ActiveForm::begin([
    'id' => 'my-form',
    'enableAjaxValidation' => true,
    'validationUrl' => Url::to(['site/validate']),
]);

// 表单字段

ActiveForm::end();
?>

public function actionValidate()
{
    $model = new MyModel();
    $model->load(Yii::$app->request->post());

    // 执行验证逻辑

    if (Yii::$app->request->isAjax) {
        Yii::$app->response->format = Response::FORMAT_JSON;
        return ActiveForm::validate($model);
    }
}

$('#my-form').on('beforeSubmit', function(e) {
    var form = $(this);

    $.ajax({
        url: form.attr('action'),
        type: 'post',
        data: form.serialize(),
        success: function(data) {
            // 处理验证结果
        }
    });

    return false;
});
