JS;

$this->registerJs($js);

When using `return false` to prevent submission, there is no need to use ` e.preventDefault()` on the `submit` event:
 
 
 
```php 
<?php
 
$js = <<<JS
 
// get the form id and set the event
 
$('form#{$model->formName()}').on('beforeSubmit', function(e) {
 
    // return false to prevent submission
 
    return false;
 
}).on('submit', function(e){    // can be omitted
 
    e.preventDefault();         // can be omitted
 
});
 
JS;
 
 
 
$this->registerJs($js);
 
 
```
