module QuietPrototype::QuietPrototypeHelper

The helper module - methods for use within views.

Public Instance Methods

include_prototype_if_used( line_prefix = '' ) click to toggle source

Include Prototype only if used for the current view, according to the Controller. Invoke using “<%= include_quiet_prototype_if_used -%>” from within the HEAD section of an XHTML view. If you want your HTML output to be nice and tidy in terms of indentation :-) then pass a string in the optional parameter - it will be inserted before each “<script>” tag in the returned HTML fragment.

Note that a trailing newline is output so you can call the helper with the “-%>” closing ERB tag (as shown in the previous paragraph) to avoid inserting a single blank line into your output in the event that the plugin is not used by the current view.

def include_prototype_if_used( line_prefix = '' )
  if using_quiet_prototype?
    "#{ javascript_include_tag( :defaults ).gsub( /^/, line_prefix ) }\n".html_safe()
  end
end

Returns ‘true’ if configured to use the Prototype library for the view related to the current request. See the “uses_prototype” class method for more information.
