Bootbox.js Confirm choice before submitting form - php

Question

Hello I have decided to use Bootbox.js as a simple way to incorporate a bootstrap modal so that I can make the user confirm their choice before the form is posted and the changes are made.
I am using Laravel, jQuery, Bootstrap and Bootbox.js in my default layout file:
Layout.blade.php
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="js/vendor/jquery-1.9.1.min.js"></script>')</script>
<script src="js/plugins.js"></script>
<script src="js/main.js"></script>
<script src="js/vendor/bootstrap.js"></script>
<script src="js/vendor/modernizr-2.6.2.min.js"></script>
<script src="js/vendor/bootbox.js"></script>
User Page:
{{Form::open('choice')}}
#foreach($items as $item)
<tr>
<td>{{ HTML::image($item->image, '', array('class' => 'img img-rounded', 'width' => '100px', 'height' => '100px')) }}</td>
<td>{{$item->name}}</td>
<td>{{ $item->desc }}</td>
<td>{{ Form::radio('item', $item->item_id)}}</tr>
#endforeach
</tbody>
</table>
{{ Form::submit('Confirm Choice', array('class' => 'btn btn-success btn-block')) }}
<script>
$(document).ready(function() {
$(document).on("click", ".alert", function(e) {
bootbox.confirm("Are you happy with the decision you have made?", "I have changed my mind", "I am happy with my choice", function(result) {
if (result) {
console.log("user confirmed");
} else {
console.log("user declined");
}
});
});
});
</script>
{{Form::close()}}
I do not know how to make the modal appear before and prevent submission. But only post if the user has confirmed their choice?

Adding e.preventDefault() in the onClick handler will prevent the form submission.
<script>
$(document).ready(function() {
$(document).on("click", ".alert", function(e) {
e.preventDefault();
bootbox.confirm("Are you happy with the decision you have made?", "I have changed my mind", "I am happy with my choice", function(result) {
if (result) {
console.log("user confirmed");
} else {
console.log("user declined");
}
});
});
});
</script>
