Want to send a DELETE request when outside of a form? This will handle the form-creation bits for you dynamically, similar to the Rails implementation. (Requires jQuery, but doesn't have to.) To use, import script, and create a link with the `data-method="DELETE"` attribute.

laravel.js

/*
<a href="posts/2" data-method="delete"> <---- We want to send an HTTP DELETE request

- Or, request confirmation in the process -

<a href="posts/2" data-method="delete" data-confirm="Are you sure?">
*/

(function() {

  var laravel = {
    initialize: function() {
      this.methodLinks = $('a[data-method]');

      this.registerEvents();
    },

    registerEvents: function() {
      this.methodLinks.on('click', this.handleMethod);
    },

    handleMethod: function(e) {
      var link = $(this);
      var httpMethod = link.data('method').toUpperCase();
      var form;

      // If the data-method attribute is not PUT or DELETE,
      // then we don't know what to do. Just ignore.
      if ( $.inArray(httpMethod, ['PUT', 'DELETE']) === - 1 ) {
        return;
      }

      // Allow user to optionally provide data-confirm="Are you sure?"
      if ( link.data('confirm') ) {
        if ( ! laravel.verifyConfirm(link) ) {
          return false;
        }
      }

      form = laravel.createForm(link);
      form.submit();

      e.preventDefault();
    },

    verifyConfirm: function(link) {
      return confirm(link.data('confirm'));
    },

    createForm: function(link) {
      var form = 
      $('<form>', {
        'method': 'POST',
        'action': link.attr('href')
      });

      var token = 
      $('<input>', {
        'type': 'hidden',
        'name': 'csrf_token',
          'value': '<?php echo csrf_token(); ?>' // hmmmm...
        });

      var hiddenInput =
      $('<input>', {
        'name': '_method',
        'type': 'hidden',
        'value': link.data('method')
      });

      return form.append(token, hiddenInput)
                 .appendTo('body');
    }
  };

  laravel.initialize();

})();

If the event is not firing it is probably because document is not ready yet. Try this: https://gist.github.com/hakankozakli/3b76daa8cb49193f366178b98b64b71d

This would even work in bootstrap-modal and dynamic inserted button.

Return response must be:

{
    "success":true,
    "hide":false,
    "reload":false,
    "remove":false,
    "message":"Deleted!"
}

How would I then send any data that is outside of the form to the form, if the form is appended to the body?

i.e. I have multiple checkboxes in a table. How would these get sent to the form so they can be deleted?

Here's a Vue version - https://gist.github.com/kevdotbadger/7dfd81d51c975156b50a717908cba891

turn your <a href="MY_PUT_URL" class="button">Go!</a> into <method-link href="MY_PUT_URL" method="PUT" classes="button">Go!</method-link>

Nice one Jeffrey, Thanks!

Thank you @JeffreyWay just what i needed you rock!

Here's a simple update that uses vanilla JS and a default confirmation message: https://gist.github.com/guilhermemuller/114064dfe4e8ee49c37cce6f1a824081

add <meta name="csrf-token" content="{{ csrf_token() }}" /> into head
then
Change below code

        'name': 'csrf_token',
        'value': '<?php echo csrf_token(); ?>' // hmmmm...

into

        'name': '_token',
	'value': document.getElementsByName('_token')[0].value,

else it gives 419 | PAGE EXPIRED Error
