Yii2 success modal window - ajax

Question

In view I have a form:
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'name')->textInput(['maxlength' => true, 'placeholder' => 'Name'])->label(false) ?>
<?= $form->field($model, 'phone')->textInput(['maxlength' => true, 'placeholder' => 'Phone'])->label(false) ?>
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
<?php ActiveForm::end(); ?>
Controller is:
if ($model->load(Yii::$app->request->post()) && $model->save()) {
\Yii::$app->session->setFlash('success', 'Created');
}
return $this->redirect(Yii::$app->request->referrer);
Then in view I put a modal:
<?php if (Yii::$app->session->hasFlash('success')) :?>
<!-- <div class="container">
<?= Yii::$app->session->getFlash('success', null, true) ?>
</div> -->
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Modal header</h3>
</div>
<div class="modal-body">
<p><?= Yii::$app->session->getFlash('success', null, true) ?></p>
</div>
<div class="modal-footer">
Close
Save changes
</div>
</div>
<?php endif ;?>
And JS code is:
$(window).load(function(){
$('#myModal').modal('show');
});
I want to open success modal window after clicking submit button. But now nothing happens. Just reloads the page. How to do that I want? And please explain how to do that without reloading the page.

Answer 1

This might be no the best decidion, but i use class myAjaxModalClass and a simple js code, that submit all form with that class via ajax and parse json result:
{result:0, data:'new modal content'}
That allows me to load form with validation erros without page reloading. Also you may add your result status to submit redirect. Expample:
{result: 2, url:'http://yoursite.net'}
