Plugins - JavaScript Fu

JavaScript Fu Rails Plugin

This plugin adds helpers, rake tasks, and rspec matchers for JavaScript development.

  git clone git://github.com/osteele/javascript_fu.git vendor/plugins/javascript_fu --depth 1

The existing notes and statistics tasks are extended to compass the public/javascript directory:

  rake statistics
  rake notes

The new onload generator method generates code that executes the content of the block upon the completion of page load.

  page.onload do
    page.call alert', 'page loaded!'
  end

generates

  Event.observe("window", "load", function() { alert("page loaded!"); });

  $(document).ready(function() { alert("page loaded!"); });

Use these in your specs to verify that a view is calling a JavaScript function:

  response.should call_js('fn')
  response.should call_js('fn(true)')
  response.should call_js('gApp.setup')

If there is a body, the arguments to the call are parsed (as JSON) and passed to it:

  # response includes <script>...fn('string', 2)...</script>
  response.should call_js(fn') do |args|
    args.should == ['string', 2]
  end
