JQueryPlugin

jQuery JavaScript library for Foswiki

Description

"jQuery is a fast, concise, JavaScript Library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages."

Powered by WikiRing Consultants

Besides jQuery itself, JQueryPlugin comes with a selection of third party plugins that are thought to be essential for modern web applications. These are integrated into Foswiki either by means of a special macro, by "minimal markup", or custom javascript initializer. "Minimal markup" is a way to avoid the need to write javascript code to initialize the interface. Instead, a special css class is added to an html element that triggers its initialization. See JQueryMetadata for an example.

Use JQREQUIRE to make use of a specific jQuery plugin on a page. This will prepare the page by loading the required javascript and css components. If you need to make a feature available on each and every page of your site, you may add this plugin to the list of default plugins loaded automatically. See configure.

Those plugins coming with their own macro will take care of loading their javascript and css by themselves. So you won't need to call JQREQUIRE explicitly for those listed below.

Adding new plugins

The JQuery ecosystem has a huge number of plugins - more than can be included by default by this plugin. If you want to add new plugins, then you will find instructions for adding them at Foswiki:Development.UsingJQueryWithFoswiki#adding_plugins.

Writing your own Javascript

Whether writing your own plugins or writing Javascript code in topics, you should observe the Foswiki JQueryCodingStandards.

  Multiple tabpanes can be nested using the following scheme:

  %TABPANE%
   %TAB{"tab 1"}%
     %TABPANE%
       %TAB{"tab 1.1"}%
         ...
       %ENDTAB%
       %TAB{"tab1.2"}%

JQREQUIRE{"plugin, plugin, ... "} -- enable a plugin on the current page

• This macro will load a list of plugins to be added to the current page. Use JQPLUGINS to display the list of available and active plugins. While loading a plugin, additional plugins it may depend on are loaded as well. Information about these dependencies is stored within the plugins themselves and can't be changed. Dependencies also make sure the javascript code is added to the html page in the right order. It uses ADDTOZONE to aggregate javascript and css at the right place on the html page.
• Parameters:

  Parameter:	Description:	Default:
  "plugin[, plugin, plugin]"	list of plugins to be loaded
  warn	(on/off) allows you to switch off warnings when a plugin was not found	on

• Related: JQueryPlugin, VarJQPLUGINS, VarADDTOZONE

JQTHEME{"name" ...} -- switch jQuery UI theme

• Foswiki's default UI theme is configured in $Foswiki::cfg{JQueryPlugin}{JQueryTheme} and defaults to base. Use configure to change this site wide. Use JQTHEME if you decide to use a different theme on the current page.
• Note: some Foswiki skins may come with their own jQuery UI matching the overall user experience of the web design.
• Parameters:

  Parameter:	Description:	Default:
  "name"	name of theme: JQueryPlugin knows the following themes base, lightness, redmod, smoothness; additional themes maybe created using the themeroller and installed to /foswiki/pub/System/JQueryPlugin/$name	base

Available jQuery plugins

1. bgiframe

A jQuery plugin that helps ease the pain when having to deal with IE z-index issues. This plugin is enabled by default.

2. blockUI

The jQuery BlockUI Plugin lets you simulate synchronous behavior when using AJAX, without locking the browser. When activated, it will prevent user activity with the page (or part of the page) until it is deactivated. BlockUI adds elements to the DOM to give it both the appearance and behavior of blocking user interaction.

3. Button (active)

This is a simple way to render nice buttons in Foswiki. It can be used to replace submit and reset buttons of html forms as well. FamFamFamContrib is recommended to display nice icons on buttons. Note, that this widget does not participate on the jquery theme roller. This is independent.

4. Cookie

Easy cookie handling using jQuery.

5. Corner

This plugin adds cross-browser support for rounded corners. For modern browsers the appropriate css attributes are used while there is a fallback strategy for others.

6. Cycle

The jQuery Cycle Plugin is a lightweight slideshow plugin. Its implementation is based on the JQueryInnerFade Plugin by Torsten Baldes, the Slideshow Plugin by Matt Oakes, and the jqShuffle Plugin by Benjamin Sterling. It supports pause-on-hover, auto-stop, auto-fit, before/after callbacks, click triggers and many transition effects. It also supports, but does not require, the Metadata Plugin and the Easing Plugin.

7. Debug

Simple jQuery logger / debugger using firebug's console or a div of its own of the form. Useful for JavaScript developers.

8. Easing

Uses the built in easing capabilities added In jQuery 1.1 to offer additional "easing" effects.

9. Farbtastic

Farbtastic is a jQuery plug-in that can add one or more color picker widgets into a page. Each widget is then linked to an existing element (e.g. a text field) and will update the element's value when a color is selected. Farbtastic uses layered transparent PNGs to render a saturation/luminance gradient inside of a hue circle. No Flash or pixel-sized divs are used.

There's a color formfield for easy integration into Foswiki DataForms.

10. FluidFont

Recompute the font size of an element based on its width.

11. Focus

This plugin sets the focus on a form input field or textarea of a form when the page is loaded.

12. Form

The jQuery Form Plugin allows you to easily and unobtrusively upgrade HTML forms to use AJAX. The main methods, ajaxForm and ajaxSubmit, gather information from the form element to determine how to manage the submit process. Both of these methods support numerous options which allows you to have full control over how the data is submitted. Submitting a form with AJAX doesn't get any easier than this!

13. Foswiki (active)

This is plugin takes care of loading the jQuery core and default plugins and performs any initialization steps specific to Foswiki, For instance, it reads all <meta> tags from the html head as they have been set by Foswiki and constructs the foswiki javascript object to be used by other javascript plugins.

In addition it adds some basic Foswiki tags to make life easier using jQuery plugins, most notably %JQREQUIRE{"pluginName"}% to load a subsequent jQuery plugin and all of its dependencies, taking care where and how it is added to the html page.

Curent default plugins are: jquery.easing, jquery.metadata, jquery.bgiframe, jquery.hoverIntent

14. Gradient

Adds a gradient to the background of an element.

15. hoverIntent

hoverIntent is similar to jQuery's built-in "hover" function except that instead of firing the onMouseOver event immediately, hoverIntent checks to see if the user's mouse has slowed down (beneath the sensitivity threshold) before firing the onMouseOver event.

16. InnerFade

InnerFade is a small plugin for the jQuery-JavaScript-Library. It's designed to fade you any element inside a container in and out. These elements could be anything you want, e.g. images, list-items, divs. Simply produce your own slideshow for your portfolio or advertisings. Create a newsticker or do an animation.

17. LiveQuery (active)

Live Query utilizes the power of jQuery selectors by firing callbacks for matched elements auto-magically, even after the page has been loaded and the DOM updated.

18. Loader

This plugin allows to delay rendering parts of a page that are loaded later on asynchronously and patched into the page.

19. LocalScroll

This plugin will animate a regular anchor navigation. It will allow your visitors to navigate your site with a smooth scrolling effect.

Each time a link is clicked, the element you decide(can be the whole screen), will gradually scroll to the targeted element, instead of "jumping" as it'd normally do. JQueryScrollTo is used for the animation.

20. MaskedInput

This is a masked input plugin for the jQuery javascript library. It allows a user to more easily enter fixed width input where you would like them to enter the data in a certain format (dates,phone numbers, etc). It has been tested on Internet Explorer 6/7, Firefox 1.5/2/3, Safari, Opera, and Chrome. A mask is defined by a format made up of mask literals and mask definitions. Any character not in the definitions list below is considered a mask literal. Mask literals will be automatically entered for the user as they type and will not be able to be removed by the user.

21. Masonry

Masonry is a layout plugin for jQuery. Think of it as the flip side of CSS floats. Whereas floating arranges elements horizontally then vertically, Masonry arranges elements vertically then horizontally according to a grid. The result minimizes vertical gaps between elements of varying height, just like a mason fitting stones in a wall.

22. Media

jQuery Media Plugin for converting elements into rich media content.

Supported Media Players:

• Flash
• Quicktime
• Real Player
• Silverlight
• Windows Media Player
• iframe

Supported Media Formats:
Any types supported by the above players, such as:

• Video: asf, avi, flv, mov, mpg, mpeg, mp4, qt, smil, swf, wmv, 3g2, 3gp
• Audio: aif, aac, au, gsm, mid, midi, mov, mp3, m4a, snd, rm, wav, wma
• Other: bmp, html, pdf, psd, qif, qtif, qti, tif, tiff, xaml

23. Metadata (active)

This plugin is capable of extracting metadata from classes, random attributes, and child elements.

24. Placeholder

Creates a 'hint' or 'example' text in a textfield that disappears when the field has focus or has custom input text.

25. PNotify

Full featured plugin to show temporary floating messages for status updates, actions and errors.

26. PopUpWindow (active)

Open a page in a new window.

27. QueryObject

This extension creates a singleton query string object for quick and readable query string modification and creation. This plugin provides a simple way of taking a page's query string and creating a modified version of this with little code.

28. Rating

The Star Rating Plugin is a plugin for the jQuery Javascript library that creates a non-obstrusive star rating control based on a set of radio input boxes.

It turns a collection of radio boxes into a neat star-rating control. It creates the interface based on standard form elements, which means the basic functionality will still be available even if Javascript is disabled.

29. ScrollTo

With this plugin, you will easily scroll overflowed elements, and the screen itself. It gives you access to many different options to customize and various ways to specify where to scroll.

See also JQuerySerialScroll, JQueryLocalScroll

30. SerialScroll

This plugin allows you to easily animate any series of elements, by sequentially scrolling them. It uses JQueryScrollTo to achieve the scrolling animation.

31. ShrinkUrls

Shrinks all urls in a given container whose link text exceeds a given size and have no white spaces in it, that is don't wrap around nicely. If the text is skrunk, the original text is appended to the title attribute of the anchor.

32. SimpleModal

SimpleModal is a lightweight jQuery plugin that provides a simple interface to create a modal dialog.

Note: please consider using UI::Dialog instead.

33. Slimbox

Show images in a lightbox. Slimbox 2 is a 4 KB visual clone of the popular Lightbox 2 script by Lokesh Dhakar, written using the jQuery javascript library. It was designed to be very small, efficient, standards-friendly, fully customizable, more convenient and 100% compatible with the original Lightbox 2.

34. Superfish

Superfish is an enhanced Suckerfish-style menu jQuery plugin that takes an existing pure CSS drop-down menu (so it degrades gracefully without JavaScript). Features:

• Suckerfish-style hover support for IE6. The class added is sfHover by default but can be changed via the options object,
• Timed delay on mouseout to be more forgiving of mouse-piloting errors. Default is 800 milliseconds but can be changed via the options object
• Animation of sub-menu reveal. uses a fade-in by default but can be given a custom object to be used in the first argument of the animate function. The animation speed is also customisable but is set to ?normal? by default
• Keyboard accessibility. Tab through the links and the relevant sub-menus are revealed and hidden as needed
• Supports the hoverIntent plugin. Superfish automatically detects the presence of Brian Cherne?s hoverIntent plugin and uses its advanced hover behaviour for the mouseovers (mouseout delays are handled by Superfish regardless of the presence of hoverIntent). Using this is only an option, but a nice one. The examples on this page are using hoverIntent. If for some reason you want to use hoverIntent on your page for other plugins but do not want Superfish to use it you can set the option disableHI to true.
• Indicates the presence of sub-menus by automatically adding arrow images to relevant anchors. Arrows are fully customisable via CSS. You can turn off auto-generation of the arrow mark-up via the ?autoArrows? option if required.
• drop shadows for capable browsers ? degrades gracefully for Internet Explorer 6. Can disable shadows completely via options object.
• Can show the path to your current page while the menu is idle. The easiest way to understand this is to view the nav-bar example.
• Optional callback functions. The 'this' keyword within the handlers you attach will refer to the animated ul sub-menu. From version 1.4 there are now three other optional callbacks allowing for further enhancements and functionality to be added without needing to alter the core Superfish code.
• See supersubs companion Javascript to automatically resize menus to fit their contents.

35. Supersubs

This is a companion plugin to superfish. It resizes superfish submenus to fit their contents.

36. Tabpane

This implements an alternative tabpane widget. There is already one in jquery-ui, however as long as jquery-ui is still in flux, this alternative offers a safe substitute well integrated into Foswiki.

Individual tabs can be loaded on demand using a REST call. Installing Foswiki:Extensions/RenderPlugin is recommended for that.

Tabpanes can be nested. Tabs can be extended in height automatically. Heights can be auto-updated to follow windows resize events. Tabpanes can be established as part of reloaded content via ajax.

Note that this widget does not participate in jquery-ui themerolling. It does match JQueryButton in terms of look & feel.

37. TextboxList

Turns a text input into a Facebook like list widget with autocompletion. This plugin adds a new formfield type textboxlist to DataForms.

38. Themeswitcher

39. Tmpl

jQuery templates contain markup with binding expressions ('Template tags'). Templates are applied to data objects or arrays, and rendered into the HTML DOM

Documentation for the jQuery Templates plugin can be found on the jQuery documentation site: http://api.jquery.com/category/plugins/templates

Note: The jQuery team has decided not to take this plugin past beta. It is no longer being actively developed or maintained. The docs remain here for the time being (for reference) until a suitable replacement template plugin is ready.

For more on the history of this change, see Official Plugins: A Change in the Roadmap and jQuery Templates and JsViews: The Roadmap

40. Tooltip

Display a customized tooltip instead of the default one for every selected element. Tooltips can be added automatically to any element that has got at title attribute thus replacing the standard tooltip as displayed by the browsers with a customizable one.

Content can be reloaded using AJAX. For example, this can be used to display an image preview in a tooltip. Have a look at the thumbnail REST service of Foswiki:Extensions/ImagePlugin how to load the thumnail from the backend dynamically.

41. Treeview

Lightweight and flexible transformation of an unordered list into an expandable and collapsable tree, great for unobtrusive navigation enhancements. Supports both location and cookie based persistence.

Subtrees can be loaded on demand using AJAX. See the Foswiki:Extensions/RenderPlugin how to implement such REST handlers easily.

42. Twisty

43. UI

Widget collection for jQuery. This is the official user interface library.

44. UI::Accordion

45. UI::Autocomplete

Autocomplete, when added to an input field, enables users to quickly find and select from a pre-populated list of values as they type, leveraging searching and filtering.

By giving an Autocomplete field focus or entering something into it, the plugin starts searching for entries that match and displays a list of values to choose from. By entering more characters, the user can filter down the list to better matches.

46. UI::Button

47. UI::Datepicker

48. UI::Dialog

A dialog is a floating window that contains a title bar and a content area. The dialog window can be moved, resized and closed with the 'x' icon by default.

If the content length exceeds the maximum height, a scrollbar will automatically appear.

A bottom button bar and semi-transparent modal overlay layer are common options that can be added.

A call to $(foo).dialog() will initialize a dialog instance and will auto-open the dialog by default. If you want to reuse a dialog, the easiest way is to disable the "auto-open" option with: $(foo).dialog({ autoOpen: false }) and open it with $(foo).dialog('open'). To close it, use $(foo).dialog('close').

49. UI::Draggable

50. UI::Progressbar

51. UI::Resizable

52. UI::Slider

53. UI::Tabs

54. Validate

Very powerful client-side form validation framework (article).

55. WikiWord

This plugin allows to create a WikiWord on the base of a set of input elements. The value of these are concatenated and the result is normalized to be a valid WikiWord. For example, this can be used to derive a topic name from a free-form topic title text.

Using compressed javascript and css files

All jQuery plugins are shipped with uncompressed js and css files, as well as minified and gzip compressed. For instance the jquery.form plugin comes with the following set:

1. /foswiki/pub/System/JQueryPlugin/plugins/form/jquery.form.uncompressed.js
2. /foswiki/pub/System/JQueryPlugin/plugins/form/jquery.form.js
3. /foswiki/pub/System/JQueryPlugin/plugins/form/jquery.form.js.gz

There is a Makefile in the /foswiki/pub/System/JQueryPlugin root directory that ensures all these files are up to date. By default all files in the JQueryPlugin package are up to date, so you only have to issue a make in the root directory if you wish to modify one of the files underneath. This will update all minified and gzipped files as required. Enable the {JQueryPlugin}{Debug} flag in configure, to use the uncompressed files right away to omit the make step during development of new javascript components.

Apache can be configured to automatically use the .gz files if present using mod_rewrite as follows:

  <FilesMatch ".*\.(js|css)$">
    RewriteEngine On
    RewriteCond %{HTTP:Accept-encoding} gzip
    RewriteCond %{REQUEST_FILENAME}.gz -f
    RewriteRule ^(.*)$ %{REQUEST_URI}.gz [L,QSA]
  </FilesMatch>

  <Files *.js.gz>
    AddEncoding gzip .js
    ForceType application/x-javascript
  </Files>

  <Files *.css.gz>
    AddEncoding gzip .css
    ForceType text/css
  </Files>

So whenever the browser accepts encoding the file as gzip and the file with the .gz exists in the filesystem, then there will be an internal redirect in the server while still enforcing the original mime-type. The browser on the client side will unzip the css and js files automatically. This will drastically reduce bandwidth and speed up interactive performance.

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.

For Foswiki versions before 1.1, this plugin requires the Foswiki:Extensions.ZonePlugin to be installed. The ZonePlugin is not required for Foswiki 1.1 or later.
