Rails (3.2+) bindings for Opal JS engine.
// app/assets/application.js // The Opal runtime // = require opal // // Dom manipulation // = require opal-dom
and then just use the
As a template
You can use it for your dynamic templates too (Probably in conjunction with ERB to pass dynamic state)
# app/views/posts/show.js.opal.erb Element.id('<%= dom_id @post %>').show
As an Haml filter (optional)
Of course you need to require
haml-rails separately since its presence is not assumed
-# app/views/posts/show.html.haml %article= post.body %a#show-comments Display Comments! .comments(style="display:none;") - post.comments.each do |comment| .comment= comment.body :opal Document.ready? do Element.id('show-comments').on :click do Element.find('.comments').first.show false # aka preventDefault end end
// = require_tree ./spec
and then a spec folder with you specs!
/opal_spec from your app and reload at will.
