Rails-重新加载JS和CSS

Question

I'm using Cocoon to dynamically add fields to my forms, when buttons are pressed.

The problem is that I need to run part of my JS code to apply design changes. I'm running the JS with Document Ready, however I only add those fields afterwards.

$( document ).ready(function() {
   $('form.form').materialForm();
});

I'm using this simple material design framework, and I just need to run this:

$('form.form').materialForm();

Ideas?

EDIT:

HAML code:

.container
.row
  .col-xs-1.col-xs-offset-2
    %span.step.step-small.step-secondary 3
  .col-xs-6
    = f.fields_for :list_impacts do |ia|
      = render "folder/folder1/impacts", f: ia
    .links
      = link_to_add_association 'add impacts', f, :list_impacts, partial: 'folder/folder1/impacts'

Answer 1

Use the callbacks . So something like

$('form.form').on('cocoon:before-insert', function(e, insertedItem) {
  $(insertedItem).materialForm();
});
