Laravel Blade Form, is it possible to create a textbox input if a user selects the 'other' option?

问题

This may not be possible with blade, but I was wondering how to generate a textbox input from an 'other' option in a select dropdown. Is this possible?

{{ Form::select('showType', array(
     'Theater' => 'Theater', 
     'Club' => 'Club',
     'Festival' => 'Festival',
     'Arena' => 'Arena',
     'Closed Show' => 'Closed Show',
     'College Show' => 'College Show'
     'Other' => 'some kind of text input appears instead'
  )}}

回答1:

You'll need to use javascript to do that, Blade can't help much. But you can create, in Blade, your form input and set a hidden class to it and, when your user select the 'other' option you just have to remove that class.

You need to use JavaScript to do this because it happens on the client side. PHP and Laravel and Blade all happens on the server. An simple jQuery example:

$('select').on('change', function(){
  $('body').append("<input type='text' value='whatever'/>");
});
