Rails 4 TurboLinks and jQuery Dynamic Links Not Pl

问题:

I am developing an application in Rails 4.0 and I'm having an issue with turbolinks not playing nice with some jQuery code I have. I have a Quote model that has a related QuoteItems model. I am using accepts_nested_attributes_for and some jQuery to populate the line items form.

When I click on a link bringing me to the new_quote_path, The dynamic link doesn't fire the javascript code. When I refresh the page, the form WORKS GREAT. I like turbolinks as it is super fast, but not sure how to get this to work in development. Here's some code.

in quotes.js.coffee

jQuery ->
  $('form').on 'click', '.remove_line_items', (event) ->
  $(this).prev('input[type=hidden]').val('1')
  $(this).closest('fieldset').hide()
  event.preventDefault()

$('form').on 'click', '.add_fields', (event) ->
  time = new Date().getTime()
  regexp = new RegExp($(this).data('id'), 'g')
  $(this).before($(this).data('fields').replace(regexp, time))
  event.preventDefault()

Quotes view new.html.erb

<%= form_for @quote, :class => "hello" do |f| %>
    <fieldset>
      <p>
        <%= f.label :quote_date, "Date of Quote" %>  <br/>
        <%= f.text_field :quote_date %>
      </p>

      <p>
        <%= f.label :good_through %> <br/>
        <%= f.text_field :good_through %>
      </p>

      <p>
        <%= f.label :quote_number %><br/>
        <%= f.text_field :quote_number %>
      </p>
      <p>
        <%= f.label :customer_id, "Customer" %><br/>
        <%= select(:quote, :customer_id, Customer.all.collect {|c| [ c.fname, c.id ] }, :prompt => "Select Customer") %>
      </p>

      <%= f.fields_for :quote_items do |builder| %>
          <%= render 'quote_item_fields', :f => builder %>
      <% end %>

      <%= link_to_add_fields "Add Line Item", f, :quote_items %>

      <p>
        <%= f.submit %>
      </p>
    </fieldset>
<% end %>

I was having the same problem, if you want to keep turbolinks working and your dynamic jquery on, try this gem: jquery-turbolinks

Hope it helps

Some options:

1) turn off turbolinks - see http://blog.steveklabnik.com/posts/2013-06-25-removing-turbolinks-from-rails-4

2) use new page:load event that turbolinks fires - $(document).on('page:load', your_start_function);, see Rails Jquery doesn't work on other pages - guessing in your case it would be something like

$(document).on 'page:load' ->
  $('form').on 'click', '.remove_line_items', (event) ->
    $(this).prev('input[type=hidden]').val('1')
    $(this).closest('fieldset').hide()
    event.preventDefault()

Maybe it will help:

$(document).on "turbolinks:load", ->
  $('#some_element_id').click ->
     alert "Clicked!"

Turbo links uses AJAX which means any dynamically generated elements never get their ready events assigned (because the page isn't technically loading after the first load). Instead, you need to listen to the top DOM element body or document and then specify a selector for the dynamic element to listen to:

$('body').on('click', '.remove_line_items', function(e) { ... });
