* Added PrototypeHelper::JavaScriptGenerator and PrototypeHelper#update_page for easily modifying multiple elements in an Ajax response. [Sam Stephenson] Example:
update_page do |page|
page.insert_html :bottom, 'list', '<li>Last item</li>'
page.visual_effect :highlight, 'list'
page.hide 'status-indicator', 'cancel-link'
end
generates the following JavaScript:
new Insertion.Bottom("list", "<li>Last item</li>");
new Effect.Highlight("list");
["status-indicator", "cancel-link"].each(Element.hide);
* Refactored JavaScriptHelper into PrototypeHelper and ScriptaculousHelper [Sam Stephenson]
* Update to latest script.aculo.us version (as of [3031])
* Updated docs for in_place_editor, fixes a couple bugs and offers extended support for external controls [Justin Palmer]

module Helpers
# Provides a set of helpers for calling JavaScript functions and, most importantly, to call remote methods using what has
# been labelled AJAX[http://www.adaptivepath.com/publications/essays/archives/000385.php]. This means that you can call
# actions in your controllers without reloading the page, but still update certain parts of it using injections into the
# DOM. The common use case is having a form that adds a new element to a list without reloading the page.
# Provides functionality for working with JavaScript in your views.
#
# == Ajax, controls and visual effects
#
# * For information on using Ajax, see
# ActionView::Helpers::PrototypeHelper.
# * For information on using controls and visual effects, see
# ActionView::Helpers::ScriptaculousHelper.
#
# To be able to use the JavaScript helpers, you must include the Prototype JavaScript Framework and for some functions
# script.aculo.us (which both come with Rails) on your pages. Choose one of these options:
# == Including the JavaScript libraries into your pages
#
# * Use <tt><%= javascript_include_tag :defaults %></tt> in the HEAD section of your page (recommended):
# The function will return references to the JavaScript files created by the +rails+ command in your
# <tt>public/javascripts</tt> directory. Using it is recommended as the browser can then cache the libraries
# instead of fetching all the functions anew on every request.
# * Use <tt><%= javascript_include_tag 'prototype' %></tt>: As above, but will only include the Prototype core library,
# which means you are able to use all basic AJAX functionality. For the script.aculo.us-based JavaScript helpers,
# like visual effects, autocompletion, drag and drop and so on, you should use the method described above.
# * Use <tt><%= define_javascript_functions %></tt>: this will copy all the JavaScript support functions within a single
# script block.
# Rails includes the Prototype JavaScript framework and the Scriptaculous
# JavaScript controls and visual effects library. If you wish to use
# these libraries and their helpers (ActionView::Helpers::PrototypeHelper
# and ActionView::Helpers::ScriptaculousHelper), you must do one of the
# following:

# DOM object whose id can be specified with <tt>options[:update]</tt>.
# Usually, the result would be a partial prepared by the controller with
# either render_partial or render_partial_collection.
#
# Examples:
# link_to_remote "Delete this post", :update => "posts", :url => { :action => "destroy", :id => post.id }
# link_to_remote(image_tag("refresh"), :update => "emails", :url => { :action => "list_emails" })
#
# You can also specify a hash for <tt>options[:update]</tt> to allow for

#
# Example:
# link_to_remote "Delete this post",
# :url => { :action => "destroy", :id => post.id },
# :update => { :success => "posts", :failure => "error" }
#
# Optionally, you can use the <tt>options[:position]</tt> parameter to influence
# how the target DOM element is updated. It must be one of
# <tt>:before</tt>, <tt>:top</tt>, <tt>:bottom</tt>, or <tt>:after</tt>.
#
# By default, these remote requests are processed asynchronous during
# which various JavaScript callbacks can be triggered (for progress indicators and
# the likes). All callbacks get access to the <tt>request</tt> object,
# which holds the underlying XMLHttpRequest.
#
# To access the server response, use <tt>request.responseText</tt>, to
# find out the HTTP status, use <tt>request.status</tt>.
#
# Example:
# link_to_remote word,
# :url => { :action => "undo", :n => word_counter },
# :complete => "undoRequestCompleted(request)"
#
# The callbacks that may be specified are (in order):
#
# <tt>:loading</tt>:: Called when the remote document is being
# loaded with data by the browser.
# <tt>:loaded</tt>:: Called when the browser has finished loading
# the remote document.
# <tt>:interactive</tt>:: Called when the user can interact with the
# remote document, even though it has not
# finished loading.
# <tt>:success</tt>:: Called when the XMLHttpRequest is completed,
# and the HTTP status code is in the 2XX range.
# <tt>:failure</tt>:: Called when the XMLHttpRequest is completed,
# and the HTTP status code is not in the 2XX
# range.
# <tt>:complete</tt>:: Called when the XMLHttpRequest is complete
# (fires after success/failure if they are present).,
#
# You can further refine <tt>:success</tt> and <tt>:failure</tt> by adding additional
# callbacks for specific status codes:
#
# Example:
# link_to_remote word,
# :url => { :action => "action" },
# 404 => "alert('Not found...? Wrong URL...?')",
# :failure => "alert('HTTP Error ' + request.status + '!')"
#
# A status code callback overrides the success/failure handlers if present.
#
# If you for some reason or another need synchronous processing (that'll
# block the browser while the request is happening), you can specify
# <tt>options[:type] = :synchronous</tt>.
#
# You can customize further browser side call logic by passing
# in JavaScript code snippets via some optional parameters. In
# their order of use these are:
#
# <tt>:confirm</tt>:: Adds confirmation dialog.
# <tt>:condition</tt>:: Perform remote request conditionally
# by this expression. Use this to
# describe browser-side conditions when
# request should not be initiated.
# <tt>:before</tt>:: Called before request is initiated.
# <tt>:after</tt>:: Called immediately after request was
# initiated and before <tt>:loading</tt>.
# <tt>:submit</tt>:: Specifies the DOM element ID that's used
# as the parent of the form elements. By
# default this is the current form, but
# it could just as well be the ID of a
# table row or any other DOM element.

# <tt>:failure</tt>:: Called when the XMLHttpRequest is completed,
# and the HTTP status code is not in the 2XX
# range.
# <tt>:complete</tt>:: Called when the XMLHttpRequest is complete
# (fires after success/failure if they are
# present).
#
# You can further refine <tt>:success</tt> and <tt>:failure</tt> by
# adding additional callbacks for specific status codes.
#
# Example:
# link_to_remote word,
# :url => { :action => "action" },
# 404 => "alert('Not found...? Wrong URL...?')",
# :failure => "alert('HTTP Error ' + request.status + '!')"
#
# A status code callback overrides the success/failure handlers if
# present.
#
# If you for some reason or another need synchronous processing (that'll
# block the browser while the request is happening), you can specify
# <tt>options[:type] = :synchronous</tt>.
#
# You can customize further browser side call logic by passing in
# JavaScript code snippets via some optional parameters. In their order
# of use these are:
#
# <tt>:confirm</tt>:: Adds confirmation dialog.
# <tt>:condition</tt>:: Perform remote request conditionally
# by this expression. Use this to
# describe browser-side conditions when
# request should not be initiated.
# <tt>:before</tt>:: Called before request is initiated.
# <tt>:after</tt>:: Called immediately after request was
# initiated and before <tt>:loading</tt>.
# <tt>:submit</tt>:: Specifies the DOM element ID that's used
# as the parent of the form elements. By
# default this is the current form, but
# it could just as well be the ID of a
# table row or any other DOM element.

# * <tt>:action</tt>: Valid options are :update (assumed by default),

# * <tt>:position</tt> If the :action is :update, you can optionally
# specify one of the following positions: :before, :top, :bottom,
# :after.
#
# Examples:
# <%= javascript_tag(update_element_function("products",

# <p>Product 1</p>
# <p>Product 2</p>
# <% end %>
# <%= javascript_tag(replacement_function) %>
#
# This method can also be used in combination with remote method call
# where the result is evaluated afterwards to cause multiple updates on
# a page. Example:
#
# # Calling view
# <%= form_remote_tag :url => { :action => "buy" },
# :complete => evaluate_remote_response %>
# all the inputs here...
#
# # Controller action
# def buy

# Provides a set of helpers for calling Scriptaculous JavaScript

#
# To be able to use these helpers, you must include the Prototype
# JavaScript framework and the Scriptaculous JavaScript library in your
# pages. See the documentation for ActionView::Helpers::JavaScriptHelper
# for more information on including the necessary JavaScript.
#
# The Scriptaculous helpers' behavior can be tweaked with various options.
# See the documentation at http://script.aculo.us for more information on
# using these helpers in your application.

# <%= drop_receving_element (...), :loading => visual_effect(:fade) %>
