I'm trying to figure out how to incorporate jQuery and javascript in my rails 4 app. I'm struggling.
I have each of these gems in my gem file:
gem 'sass-rails', '~> 5.0'
gem 'bootstrap-sass', '~> 3.3.5.1'
gem 'jquery-rails'
gem 'jquery-ui-rails'
I have a number of conflicts (the last 5 of my questions and most recent bounty all relate to these). See attached links:
http://stackoverflow.com/questions/36734854/rails-4-jquery-conflicts-with-javascript
http://stackoverflow.com/questions/36832276/rails-4-jquery-conflicts-and-function-error
http://stackoverflow.com/questions/36831987/rails-4-jquery-to-hide-initially-then-toggle-with-click
http://stackoverflow.com/questions/36614651/rails-4-conditional-js-with-dependent-fields-rails
In order to try to work around one aspect of these problems, I removed the dependent-rails gem and am trying to write my own function to hide a section of my projects/form until a question in that form is answered by checking a box (so its value is true).
I currently have a projects.js file in my app/assets/javascripts folder. It has:
(function($){
$(document).ready(function() {
$("#check_project_milestones").hide()
});
})(jQuery);
While this formulation (the first and last line are new) does stop one error (which before including the first and last line said "Uncaught TypeError: $ is not a function(anonymous function) @ projects.self-9c019ba….js?"), it doesnt actually work to hide the text inside the id tag 'check_project_milestones'.
The form has:
<%= f.input :has_milestones, as: :boolean, boolean_style: :inline, :label => 'Does this research project have identifiable milestones or decision points?', id: 'check_project_milestones' %>
<%= content_tag :div, data: {'checkbox-id': 'check_project_milestones', 'checkbox-value': 'true' } do %>
<div class="intpol2">
Milestones
</div>
<%= f.simple_fields_for :milestones do |f| %>
<%= render 'milestones/milestone_fields', f: f %>
<% end %>
<% end %>
<div class="row">
<div class="col-md-6">
<%= link_to_add_association 'Add a milestone', f, :milestones, partial: 'milestones/milestone_fields' %>
</div>
</div>
My application.js has:
//= require jquery
//= require jquery-ui
//= require bootstrap-sprockets
//= require jquery_ujs
//= require html.sortable
//= require disqus_rails
//= require moment
//= require bootstrap-datetimepicker
//= require pickers
//= require main

//= require jquery.parallax-1.1.3
//= require jquery.properload
//= require jquery.shuffle.modernizr.min
//= require jquery.sudoSlider.min
//= require jquery.superslides.min
//= require masonry.pkgd.min
//= require rotaterator
//= require smoothscrolljs
//= require waypoints.min
//= require wow.min
//= require gmaps/google
//= require chosen-jquery
//= require cocoon
//= require imagesloaded.pkgd.min
//= require isotope.pkgd.min
//= require jquery.counterup.min
//= require jquery.pjax
//= require custom.js
//= require slider
//= require underscore
//= require bootstrap-slider
//= require_tree .
Can anyone see what I have done wrong?
