NAME

6       HTML::Prototype::Js - prototype library, embedded in perl
7

SYNOPSIS

9           our $prototype = do { package HTML::Prototype::Js; local $/; <DATA> };
10

DESCRIPTION

12       This is the actual Prototype library embedded in a perl __DATA__
13       section, for easy inclusion in HTML::Prototype.
14

NEW SYNTAX

16       The prototype library  provides some functions and classes which
17       effectively change the basic syntax of the JavaScript you write.
18
19       $(element)
20           This function takes an element / element list and gets all string
21           elements using document.getElementbyId. This is probably one of the
22           most common functions when using javascript for web development, so
23           it will save you a lot of typing.
24
25       Class
26           This uses fucntion references to allow namespace-like Class
27           structures in javascript.
28
29       Object.extend
30           Simple inheritance for javacsript. Will set all properties of the
31           child in the parent.
32
33       Function.bind
34           Allow function refs to be full object method references, through
35           the use of extend and apply
36
37       Try.these
38           Simple try/catch for a list of functions, will return the return
39           value of the first that doesn't throw an exception.
40
41       Array.push
42           implement push for arrays. returns number of elements in result.
43
44       Function.apply
45           Call a function on a given object, using eval.
46

JS OBJECTS

48       The Prototype library provides a number of classes you can use to
49       improve interaction with the end user.
50
51       Ajax
52           Provides one useful function, getTransport. This function will
53           return a XMLHttpRequest object suitable for your browser.
54
55       Ajax.Base
56           An abstract base class for the Ajax objects described below. Sets
57           some common options for Ajax objects;
58             method: http method, defaults to post.
59             asynchronous: process in the background, true/false, defaults to
60           true.
61             parameters: extra parameters, defaults to blank.
62
63       Ajax.Updater
64           a subclass of Ajax.Base, this class uses Ajax.Request to populate a
65           container in your web page. Takes container, url and Ajax.Base
66           options as paramters.
67
68       Ajax.Request
69           This object represents a plain ajax request. It extends base to add
70           a constructor, as well as some events to handle events.  The
71           constructor takes  an url, as well as the options described in
72           Ajax.Base.  Currently handles the following events:
73             'Uninitialized', 'Loading', 'Loaded', 'Interactive', 'Complete'
74
75       Effect.Appear
76           Takes an element, and makes that element appear through a fade.
77
78       Effect.ContentZoom
79           Takes an element, and zooms the content of that element.
80
81       Effect.Fade
82           Takes an element, and makes that element fade out and disappear.
83
84       Effect.Highlight
85           Takes an element, and does a highlight of that element.
86
87       Effect.Puff
88           Takes an element, and makes that element "blow up" and disappear.
89           (As in disappear in a puff of smoke).
90
91       Effect.Scale
92           Takes an element, and a size, in percent, and scales that element
93           to the given size. If it's a div, the initial size will have to be
94           given in EM. No such restrictions for pictures.
95
96       Effect.Squish
97           Takes an element, and shrinks that element until it disappears.
98
99       Element
100           A collection of functions related to basic elements. takes one or
101           more elements.
102             toggle: Toggles the element display style.
103             hide: Turns off the element's display style.
104             show: Turns on the element's display style.
105             remove: Delete this element from the DOM.
106             getHeight: Get the element height.
107
108           Also provides a convenience object, Toggle, with one method display
109           which aliases to toggle, so you can call it as
110             Toggle.display(element)
111
112       Field
113           Adds some useful functions to HTML Fields with several elements:
114             clear: remove all content.
115             focus: Give the element focus.
116             present: returns true if all arguments are filled in, false
117           otherwise.
118             select(element): Select the given element in a form.
119             activate(element): give the selected element focus, and select
120           it.
121
122       Form
123           Some useful utilies for HTML Forms. all of these take a form
124           element as sole argument.
125             serialize: returns a URL serialized version of a given form.
126             getElements: returns all elements in the form.
127             disable: blurs and disables every element in the form.
128             focusFirstElement: Give first element in the form focus.
129             reset: reset all form elements.
130
131       Form.Element
132           Some useful objects for Form Field Elements. These take an element
133           as the sole argument.
134             serialize: url encode the element for use in a URI string.
135             getValue: returns the value of the given element.
136
137       Form.Element.Observer
138       Form.Element.Serializers
139           Serializers for various element types. Takes the input element as
140           argument.
141             input: determines the element type, and chooses the right
142           serializer.
143             inputSelector: serialize checkbox/radio.
144
145       Form.Element.Observer
146       Insertion
147           This can be used in place of a innerHTML, to insert the content
