I have a function that I want called on submission of my Laravel Form for Ajax purposes. How can I go about this where the page does not submit and reload?

This works: (but the Enter btn does not execute)

<?php echo Form::open(); ?>

    <?php echo Form::button('Search', array('id'=>'searchbtn', 'class'=>'button radius right', 'onclick'=>'myFunction(this.form)')); ?>

<?php echo Form::close(); ?>

This does not:

<?php echo Form::open(array('onsubmit' => 'myFunction(this)')); ?>

    <?php echo Form::submit('Search', null, array('id'=>'searchbtn', 'class'=>'button radius right')); ?>

<?php echo Form::close(); ?>
