What is jQuery anyway?

A JavaScript library which simplifies the common every day web development tasks of Document Model manipulation, event handling, animation and AJAX/JSON

Created: June 2006 by John Resig

Removes browser dependencies

Open Source (MIT License)


60% of world’s top 10,000 websites use jQuery http://trends.builtwith.com/javascript (*Dec 2012)

Used by Microsoft .Net v4 as part of the ASP.NET AJAX framework Some websites you probably know using jQuery

Amazon Google Twitter Dell Wordpress Bank of America Stackoverflow Drupal BestBuy Wordpress

http://trends.builtwith.com/javascript





Core– Document Model (DOM) Manipulation– Simple Animations

UI– Pre-packages functional capabilities– Analogous to Dojo Widgets

Mobile– A unified, HTML5-based user interface system for all popular mobile device platforms, built on the rock-solid jQuery and jQuery UI foundation.

Agenda

What is jQuery?







Dojo and jQuery have the same basic premise:– Browser compatibility / Code simplification

Many similar capabilities.– DOM manipulation– Widgets (Date pickers, sliders etc)

Many differences– Dojo intended for larger client applications– jQuery intended to make coding as easy as possible

Where’s the balance?

Many factors determine the balance– Network connectivity– Functional requirements– Developmental experience with Dojo/jQuery– Project timeline– Maintainability of the application– jQuery v2.0 (future) will not support IE<9• “The entire jQuery core team instantly became giddy as they started

ripping out oldIE support for jQuery 2.0.” 17 Dec 2012 - Scott González (jQuery contributor)

Don’t use jQuery when….

There isn’t a justifiable reason to use it

jQuery is an additional download (~94k)– Version 1.8 does allow for exclusion of code which is not

necessary

When not to use jQuery :– Simple DOM manipulation– To provide functionality which is already provided by Dojo

Widgets– To determine runtime events in the onLoad event– If you are using OneUI (*not for beginners)– Because you don’t want to learn Dojo

Use jQuery when……

Enhanced functionality not provided by Dojo– Specific jQuery or jQuery UI functionality– Specific Animation requirements– Broader browser compatibility

The business plan supports jQuery usage

The requirements are best suited to a jQuery solution

How does jQuery work - API References

Example API reference methods and propertieshttp://api.jquery.com

API references Examples

Selectors (“ELEMENT”) (“.class”) (“#idTag”)

Attributes .attr() .html() .toggleClass()Traversing .children() .closest() .find() Manipulation .appendTo() .css() .val() CSS .height() .position() .width() Events .blur() .bind() .keypress() Effects .animate() .fadeIn() .slideToggle()Ajax .get() .getJSON() .serialize() Utilities .grep() .each() .inArray() Internals .error() .pushStack() .context()

Select and conquer

1) Select the DOM elements you wish to affect

$(‘.myClass’)

2) Concatenate the API reference to use

$(‘.myClass’).css(‘display’, ‘none’)

3) Execute

Select all elements with a class “myClass”

Set the display style to none

Chaining

All methods/properties return a jQuery object– Allows for chaining of *all* other API references

$("p") .find(":contains('t')") .css('color','red')

Advantages– Object reuse: Lower memory consumption and faster– Shorter more manageable code – Easier syntax for beginners – Easy plugin creation

Select All Paragraph nodesWithin each node find all words containing the letter t

Color those matches red

Adding jQuery to the application

jQuery is a Client Side JavaScript library– Can be added to the application– Can be referenced externally to the database

jQuery plugins contain images and style sheets– A complete miniaturized application– More than just JavaScript Code– Could be complicated to maintain if all files were added as resources

Adding jQuery to the database

Download the jQuery library– http://jquery.com– Save in a “js” folder on your computer

http://jquery.com/

http://jquery.com/


Don’t add it to the database as a file resource

Don’t add it to the database as a js library

Domino Designer in Eclipse (DDE) reads and processes resources

– More time consuming (slows DDE)

Less maintainable


The WebContent folder– Acts like the root folder within your database– All files referenced to the .nsf/ in the URL– Much easier to maintain files in one place– Makes jQuery plugin management much easier


Drag and Drop the js folder into WebContent


Directly added to the XPage source panel

<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script>


Through a Theme<resource>

<content-type>application/x-javascript</content-type>

<href>js/jquery-1.8.3.min.js</href>

</resource>

Adding jQuery to your XPages - Example

Modernizing a notes view

Adding User interactivity

Add a basic viewPanel control to your XPage

An un-styled viewPanel

Functional but not aesthetically pleasing

Adding User interactivity - demonstration

Using jQuery, user interactivity can be added to a viewPanel to make it more functional and improve the user experience.

jQuery plugins

Extensions of the jQuery API code base

The plugin is called in the same was as a normal API reference

$(‘.myClass’).doSomething()

To achieve the desired functionality additional resources are often necessary

– CSS– Images– Other JavaScript files

jQuery plugins

Additional JavaScript Libraries– May also include • Images• CSS

– Added to your XPage database through WebContent folder as before

31

jQuery plugins - example

Joyride.js – Website feature tour

– Requirement: • Provide a visual cue for website users

to the new features available• Make it simple to use• Make it one time only

32


Joyride – Website feature tour

By clicking a button users are guided around the new website

Functionality in a box

Yesterday your boss could have said:–“I need a slideshow adding to the website by tomorrow, needs to

allow users to see thumbnails and cycle through them quickly…..”

You would have panicked

You could have remembered Google is your friend..

and found a great reference on jQuery slideshows

http://speckyboy.com/2009/06/03/15-amazing-jquery-image-galleryslideshow-plugins-and-tutorials/

You would then have responded: “Which one sir?”



Functionality in a box

Over 3000 jQuery plugins created and registered

Charting Modal WindowForm Validation MobileResponsive Layouts Web TypographySliders AnimationGalleries TablesCarousels Form Select and ComboTime and Date Pickers

And almost all of them are FREE
