Method: ActionView::Helpers::AssetUrlHelper#javascript_url

Defined in:
actionview/lib/action_view/helpers/asset_url_helper.rb

#javascript_url(source, options = {}) ⇒ Object Also known as: url_to_javascript

Computes the full URL to a JavaScript asset in the public javascripts directory. This will use javascript_path internally, so most of their behaviors will be the same. Since javascript_url is based on asset_url method you can set :host options. If :host options is set, it overwrites global config.action_controller.asset_host setting.

javascript_url "js/xmlhr.js", host: "http://stage.example.com" # => http://stage.example.com/assets/js/xmlhr.js
