// The local array autocompleter. Used when you'd prefer to
// inject an array of autocompletion options into the page, rather
// than sending out Ajax queries, which can be quite slow sometimes.
//
// The constructor takes four parameters. The first two are, as usual,
// the id of the monitored textbox, and id of the autocompletion menu.
// The third is the array you want to autocomplete from, and the fourth
// is the options block.
//
// Extra local autocompletion options:
// - choices - How many autocompletion choices to offer
//
// - partialSearch - If false, the autocompleter will match entered
// text only at the beginning of strings in the
// autocomplete array. Defaults to true, which will
// match text at the beginning of any *word* in the
// strings in the autocomplete array. If you want to
// search anywhere in the string, additionally set
// the option fullSearch to true (default: off).
//
// - fullSsearch - Search anywhere in autocomplete array strings.
//
// - partialChars - How many characters to enter before triggering
// a partial match (unlike minChars, which defines
// how many characters are required to do any match
// at all). Defaults to 2.
//
// - ignoreCase - Whether to ignore case when autocompleting.
// Defaults to true.
//
// It's possible to pass in a custom function as the 'selector'
// option, if you prefer to write your own autocompletion logic.
// In that case, the other options above will not apply unless
// you support them.

HTML::Prototype::Helper::Tag - Defines a tag object needed by HTML::Prototype
=head1 SYNOPSIS
use HTML::Prototype::Helper;
=head1 DESCRIPTION
Defines a tag object needed by HTML::Prototype
=head2 REMARKS
Until version 1.43, the internal function I<$self->_tag> used I<$tag->as_XML>
as its return value. By now, it will use I<$tag->as_HTML( $entities )> to
invokee I. This behaviour can be overridden
by setting I<$HTML::Prototype::Helper::Tag::USE_ASXML_FOR_TAG> to 1.

=head1 NAME
HTML::Prototype::Js - prototype library, embedded in perl
=head1 SYNOPSIS
our $prototype = do { package HTML::Prototype::Js; local $/; };
=head1 DESCRIPTION
This is the actual Prototype library embedded in a perl __DATA__
section, for easy inclusion in L.
=head1 NEW SYNTAX
The prototype library provides some functions and classes which effectively
change the basic syntax of the JavaScript you write.
=over 4
=item $(element)
This function takes an element / element list and gets all string elements
using document.getElementbyId. This is probably one of the most common
functions when using javascript for web development, so it will save you
a lot of typing.
=item Class
This uses fucntion references to allow namespace-like Class structures
in javascript.
=item Object.extend
Simple inheritance for javacsript. Will set all properties of the child
in the parent.
=item Function.bind
Allow function refs to be full object method references, through the use
of extend and apply
=item Try.these
Simple try/catch for a list of functions, will return the return value
of the first that doesn't throw an exception.
=item Array.push
implement push for arrays. returns number of elements in result.
=item Function.apply
Call a function on a given object, using eval.
=back
=head1 JS OBJECTS
The Prototype library provides a number of classes you can use
to improve interaction with the end user.
=over 4
=item Ajax
Provides one useful function, getTransport. This function
will return a XMLHttpRequest object suitable for your browser.
=item Ajax.Base
An abstract base class for the Ajax objects described below. Sets
some common options for Ajax objects;
B http method, defaults to post.
B process in the background, true/false, defaults to true.
B extra parameters, defaults to blank.
=item Ajax.Updater
a subclass of Ajax.Base, this class uses Ajax.Request to populate
a container in your web page. Takes container, url and Ajax.Base
options as paramters.
=item Ajax.Request
This object represents a plain ajax request. It extends base to
add a constructor, as well as some events to handle events.
The constructor takes an url, as well as the options described
in Ajax.Base.
Currently handles the following events:
'Uninitialized', 'Loading', 'Loaded', 'Interactive', 'Complete'
=item Effect.Appear
Takes an element, and makes that element appear through a fade.
=item Effect.ContentZoom
Takes an element, and zooms the content of that element.
=item Effect.Fade
Takes an element, and makes that element fade out and disappear.
=item Effect.Highlight
Takes an element, and does a highlight of that element.
=item Effect.Puff
Takes an element, and makes that element "blow up" and disappear.
(As in disappear in a puff of smoke).
=item Effect.Scale
Takes an element, and a size, in percent, and scales that element to
the given size. If it's a div, the initial size will have to be given
in EM. No such restrictions for pictures.
=item Effect.Squish
Takes an element, and shrinks that element until it disappears.
=item Element
A collection of functions related to basic elements. takes one or more elements.
B Toggles the element display style.
B Turns off the element's display style.
B Turns on the element's display style.
B Delete this element from the DOM.
B Get the element height.
Also provides a convenience object, Toggle, with one method display which aliases to toggle,
so you can call it as
Toggle.display(element)
=item Field
Adds some useful functions to HTML Fields with several elements:
B remove all content.
B Give the element focus.
B returns true if all arguments are filled in, false otherwise.
B Select the given element in a form.
B give the selected element focus, and select it.
=item Form
Some useful utilies for HTML Forms. all of these take a form element
as sole argument.
B returns a URL serialized version of a given form.
B returns all elements in the form.
B blurs and disables every element in the form.
B Give first element in the form focus.
B reset all form elements.
=item Form.Element
Some useful objects for Form Field Elements. These take an element
as the sole argument.
B url encode the element for use in a URI string.
B returns the value of the given element.
=item Form.Element.Observer
=item Form.Element.Serializers
Serializers for various element types. Takes the input element as
argument.
B determines the element type, and chooses the right serializer.
B serialize checkbox/radio.
=item Form.Element.Observer
=item Insertion
This can be used in place of a innerHTML, to insert the content into
the dom.
=item Insertion.Before
Puts content before a given dom node.
=item Insertion.Top
Puts content at the top of a given dom node.
=item Insertion.Bottom
Puts content at the bottom of a given dom node.
=item Insertion.After
Puts content after a given dom node.
=item PeriodicalExecuter
This object takes two parameters, a reference to a callback
function, and a frequency in seconds. It will execute the callback
every second.

=head1 DESCRIPTION
The module contains some code generators for Prototype, the famous JavaScript
OO library and the script.aculous extensions.
The Prototype library (http://prototype.conio.net/) is designed to make
AJAX easy. Catalyst::Plugin::Prototype makes it easy to connect to the
Prototype library.
This is mostly a port of the Ruby on Rails helper tags for JavaScript
for use in L.
=head2 METHODS
=over 4
=item $prototype->in_place_editor( $field_id, \%options )
Makes an HTML element specified by the DOM ID C<$field_id> become an in-place
editor of a property.
A form is automatically created and displayed when the user clicks the element,
something like this:
The form is serialized and sent to the server using an Ajax call, the action
on the server should process the value and return the updated value in the
body of the reponse. The element will automatically be updated with the
changed value (as returned from the server).
Required options are:
C: Specifies the url where the updated value should be sent after the
user presses "ok".
Addtional options are:
C: Number of rows (more than 1 will use a TEXTAREA)
C: The number of columns the text area should span (works for both single line or multi line).
C: Synonym for ‘cols’ when using single-line (rows=1) input
C: The text on the cancel link. (default: "cancel")
C: CSS class used for the in place edit form. (default: "inplaceeditor-form")
C: The text on the save link. (default: "ok")
C: CSS class added to the element while displaying "Saving..."
(removed when server responds). (default: "inplaceeditor-saving")
C: Will cause the text to be loaded from the server (useful if
your text is actually textile and formatted on the server)
C: If the C option is specified then this text is
displayed while the text is being loaded from the server. (default: "Loading...")
C: The text on the click-to-edit link. (default: "click to edit")
C: The id of an external control used to enter edit mode.
C: Pass through options to the AJAX call (see prototype's Ajax.Updater)
C: JavaScript snippet that should return what is to be sent in the
Ajax call, C
