Validate Yii2 Activeform on simple button click

I want to validate my Yii2 activeform on simple button click which is not submitButton. I tried

but it is not working.

I also tried -
it validates form but it also submit it if everything is ok. I don't want to submit that form. I just want to validate it on button click and if everything is ok than i want to open a modal popup.

What are possible ways to validate this activeform on button click

To validate your form perform ajax validation only inside your action as follows. This will only validate your form

public function actionValidateForm() {
        $model = new Form();

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