# = Action View JavaScript Helpers
module Helpers
# 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.
#
# == Including the JavaScript libraries into your pages
#
# 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:
#
# * Use <tt><%= javascript_include_tag :defaults %></tt> in the HEAD
# section of your page (recommended): This 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 Scriptaculous-based
# JavaScript helpers, like visual effects, autocompletion, drag and drop
# and so on, you should use the method described above.
#
# For documentation on +javascript_include_tag+ see
# ActionView::Helpers::AssetTagHelper.

module ActionView
# = Action View Scriptaculous Helpers
module Helpers
# Provides a set of helpers for calling Scriptaculous[http://script.aculo.us/]
# JavaScript functions, including those which create Ajax controls and visual
# effects.
#
# 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.
module ScriptaculousHelper
TOGGLE_EFFECTS = [:toggle_appear, :toggle_slide, :toggle_blind]
# Returns a JavaScript snippet to be used on the Ajax callbacks for
# starting visual effects.
#
# If no +element_id+ is given, it assumes "element" which should be a local
# variable in the generated JavaScript execution context. This can be
# used for example with +drop_receiving_element+:
#
# <%= drop_receiving_element (...), :loading => visual_effect(:fade) %>
#
# This would fade the element that was dropped on the drop receiving
# element.
#
# For toggling visual effects, you can use <tt>:toggle_appear</tt>, <tt>:toggle_slide</tt>, and
# <tt>:toggle_blind</tt> which will alternate between appear/fade, slidedown/slideup, and
# blinddown/blindup respectively.
#
# You can change the behaviour with various options, see
# http://script.aculo.us for more documentation.

# Makes the element with the DOM ID specified by +element_id+ sortable
# by drag-and-drop and make an Ajax call whenever the sort order has
# changed. By default, the action called gets the serialized sortable
# element as parameters.
#
# Example:
#
# <%= sortable_element("my_list", :url => { :action => "order" }) %>
#
# In the example, the action gets a "my_list" array parameter
# containing the values of the ids of elements the sortable consists
# of, in the current order.
#
# Important: For this to work, the sortable elements must have id
# attributes in the form "string_identifier". For example, "item_1". Only
# the identifier part of the id attribute will be serialized.
#
# Additional +options+ are:
#
# * <tt>:format</tt> - A regular expression to determine what to send as the
# serialized id to the server (the default is <tt>/^[^_]*_(.*)$/</tt>).
#
# * <tt>:constraint</tt> - Whether to constrain the dragging to either
# <tt>:horizontal</tt> or <tt>:vertical</tt> (or false to make it unconstrained).
#
# * <tt>:overlap</tt> - Calculate the item overlap in the <tt>:horizontal</tt>
# or <tt>:vertical</tt> direction.
#
# * <tt>:tag</tt> - Which children of the container element to treat as
# sortable (default is <tt>li</tt>).
#
# * <tt>:containment</tt> - Takes an element or array of elements to treat as
# potential drop targets (defaults to the original target element).
#
# * <tt>:only</tt> - A CSS class name or array of class names used to filter
# out child elements as candidates.
#
# * <tt>:scroll</tt> - Determines whether to scroll the list during drag
# operations if the list runs past the visual border.
#
# * <tt>:tree</tt> - Determines whether to treat nested lists as part of the
# main sortable list. This means that you can create multi-layer lists,
# and not only sort items at the same level, but drag and sort items
# between levels.
#
# * <tt>:hoverclass</tt> - If set, the Droppable will have this additional CSS class
# when an accepted Draggable is hovered over it.
#
# * <tt>:handle</tt> - Sets whether the element should only be draggable by an
# embedded handle. The value may be a string referencing a CSS class value
# (as of script.aculo.us V1.5). The first child/grandchild/etc. element
# found within the element that has this CSS class value will be used as
# the handle.
#
# * <tt>:ghosting</tt> - Clones the element and drags the clone, leaving
# the original in place until the clone is dropped (default is <tt>false</tt>).
#
# * <tt>:dropOnEmpty</tt> - If true the Sortable container will be made into
# a Droppable, that can receive a Draggable (as according to the containment
# rules) as a child element when there are no more elements inside (default
# is <tt>false</tt>).
#
# * <tt>:onChange</tt> - Called whenever the sort order changes while dragging. When
# dragging from one Sortable to another, the callback is called once on each
# Sortable. Gets the affected element as its parameter.
#
# * <tt>:onUpdate</tt> - Called when the drag ends and the Sortable's order is
# changed in any way. When dragging from one Sortable to another, the callback
# is called once on each Sortable. Gets the container as its parameter.
#
# See http://script.aculo.us for more documentation.

#
# You can change the behaviour with various options, see
# http://script.aculo.us for more documentation.
#
# Some of these +options+ include:
# * <tt>:accept</tt> - Set this to a string or an array of strings describing the
# allowable CSS classes that the +draggable_element+ must have in order
# to be accepted by this +drop_receiving_element+.
#
# * <tt>:confirm</tt> - Adds a confirmation dialog. Example:
#
# :confirm => "Are you sure you want to do this?"
#
# * <tt>:hoverclass</tt> - If set, the +drop_receiving_element+ will have
# this additional CSS class when an accepted +draggable_element+ is
# hovered over it.
#
# * <tt>:onDrop</tt> - Called when a +draggable_element+ is dropped onto
# this element. Override this callback with a JavaScript expression to
# change the default drop behaviour. Example:
#
# :onDrop => "function(draggable_element, droppable_element, event) { alert('I like bananas') }"
#
# This callback gets three parameters: The Draggable element, the Droppable
# element and the Event object. You can extract additional information about
# the drop - like if the Ctrl or Shift keys were pressed - from the Event object.
#
# * <tt>:with</tt> - A JavaScript expression specifying the parameters for
# the XMLHttpRequest. Any expressions should return a valid URL query string.
