JavaScript is an integral part of the RIA revolution. JavaScript allows developers to create rich and interactive web interfaces and establish asynchronous communication with servers for constantly up-to-date data without a page refresh.

Many things that were once accomplished using Flash objects can now be built using JavaScript – with the added benefit that it is free, typically more web and mobile accessible under most circumstances using best practices for development techniques, and without the need to use proprietary software for development.

Though JavaScript has been around for a while, new tools, techniques, and information are constantly being pumped out to continually push the technology into greater heights. In this article, we wish to share with you a huge list of fresh and new tools and resources that JavaScript developers will find useful and informative.

Here are a few other posts that you might find interesting:

Useful JavaScript Tools

FireUnit
Unit testing is an integral part of building high-performance and efficient web applications. John Resig (creator of jQuery library) and Jan Odvarko have developed an excellent Firefox/Firebug extension called FireUnit which gives developers logging and testing capabilities via a simple JavaScript API. For those interested in the tool, you should also read Odvarko’s post detailing the usage of FireUnit.

Sugar Test
SugarTest makes it easy to write elegant and understandable JavaScript tests. Its API is inspired by both RSpec, Shoulda and jQuery. It works as a DSL running on top of JsUnitTest.

JS.Class: Ruby-style JavaScript
JS.Class is a library designed to facilitate object-oriented development in JavaScript. It implements Ruby’s core object, module and class system and some of its metaprogramming facilities, giving you a powerful base to build well-structured OO programs.

JSON Formatter and Validator
The JSON Formatter was created to help with debugging. As data expressed as JSON is often written without line breaks to save space, it became extremely difficult to actually read it. This tool hopes to solve the problem by formatting the JSON into data that is easily readable by human beings.

Faux Console: Simulating a Firebug, Safari or Opera debugging in IE
Browsers like Safari, Opera and Firefox use the Firebug extension that offers a developer a comfortable way to output debugging information using the console.log() command. Microsoft Internet Explorer does not support this though – Faux Console is a small JavaScript that you can embed in the document to have a basic debugging console in IE.

JS Bin
JS Bin is a web application for testing and debugging JavaScript and CSS collaboratively. You input your source code and save it to a publicly-accessible URL which you can then share to your fellow developers or in social networking outlets like Twitter or Facebook groups. Be sure to check out the video introduction to see JS Bin in action.

PHP.JS
PHP.JS is an open source project in which we try to port PHP functions to JavaScript. By including the PHP.JS library in your own projects, you can use your favorite PHP functions client-side.

Page Speed
Page Speed, released by Google, is a Firefox/Firebug extension very similar to YSlow that evaluates your web pages for performance. Read more about Page Speed best practices to see what aspects of a web page are being evaluated. YSlow and Page Speed are based off Steve Souder’s work (who worked for Yahoo! and now works for Google).

prettyPrint
prettyPrint is an in-browser JavaScript utility for dumping variable information, inspired by ColdFusion’s built-in cfdump utility function. Using prettyPrint on JS objects, variables, and arrays will give you a large array of information about them, which you can then use for debugging purposes or simply for gathering data about them for documentation.

Spket IDE
Spket is an excellent toolkit for JavaScript and XML development. It has a robust and intuitive GUI, and integrates with popular and powerful JavaScript/Ajax libraries such as Y!UI and jQuery. Its JavaScript Formatter feature gives you unparalleled control and standardization for you or your team’s JavaScript code formatting standards.

Highlight.js
Highlight.js highlights syntax in code examples on blogs, forums and other web pages. The tool works automatically: it finds blocks of code, detects a language and highlights it accordingly.

Javascript Compressor
Javascript Compressor is a web-based tool for compressing your JavaScript to reduce their file sizes. It works by removing unnecessary characters (such as extra tabs and spaces). Developers who use the tool to compress their code can also use the decoding feature to uncompress their source code. It also obfuscates your code, making it harder to read – which can be desirable if you want to delay prying eyes from analyzing your publicly-available code base.

Firediff
Firediff is a Firefox/Firebug extension that allows you to track changes in the DOM and CSS. By logging these changes, you can gain information about how web applications work, and what elements (and what properties) are being altered by way of DOM manipulation.

RockStar Web Profiler

Tiny JS
Tiny JS is an online directory of small but powerful plugins for popular JavaScript/Ajax libraries (MooTools, jQuery, and YUI at the moment). Its aim is to hunt down and feature lightweight plugins that give you a lot of bang for the buck.

JSCharts
JS Charts is a free JavaScript based chart generator that requires little or no coding. With JS Charts drawing charts is a simple and easy task, since you only have to use client-side scripting (i.e. performed by your web browser). No additional plugins or server modules are required. It’s enough to include the scripts, prepare your chart data in XML or JavaScript Array and your chart is ready.

Glimmer
Glimmer is an interactive design tool for incorporating slick JavaScript-based animation effects using the jQuery library. Glimmer comes with a wizard-style user interface which can reduce the amount of coding that you have to write manually.

To help streamline its sites, Google has been using an internal tool called Page Speed, and starting today it’s opening up the tool to the developer community. The newly open-sourced tool is a Firefox plugin that integrates with Firebug, making suggestions on how to speed up your site based on best practices.

From the Google blog post:

For example, Page Speed automatically optimizes images for you, giving you a compressed image that you can use immediately on your web site. It also identifies issues such as JavaScript and CSS loaded by your page that wasn’t actually used to display the page, which can help reduce time your users spend waiting for the page to download and display.

If this sounds familiar, it’s because Yahoo offers a similar tool for Firefox called YSlow, which is also meant to help developers streamline their websites.

I have been very impressed with Andrew Sutherland of the Mozilla Messaging team (which is one reason that I have faith that I will dump Gmail for something he and the Messaging team come up with one day ;) and the visualizations that he is playing with are quite cool indeed. Seeing your email in different ways (not just in a table) can open the eyes.

Andrew is using Protovis “a visualization toolkit for JavaScript using the canvas element. It takes a graphical approach to data visualization, composing custom views of data with simple graphical primitives like bars and dots. These primitives are called marks, and each mark encodes data visually through dynamic properties such as color and position.”

There are some cool examples such as:

which produces .

Very cool indeed!

Allan Jardine has updated his popular DataTables rich data grid control. Allan told us what his aims were for this 1.4.1 release:

Being fairly happy with the options that DataTables presents to the end user, I’ve focused this release on providing tools for the developer. A plug-in API, non-destructive DOM manipulation (the biggest weak point of the old versions) and documentation are the major new features.

If you take a look at the new rich API you will see that can manipulate the data in the table, build filters, fetch remote data, and more.

What does DataTables feature again?

• Variable length pagination
• On-the-fly filtering
• Multi-coloum sorting with data type detection
• Smart handling of column widths
• Fully internationalisable
  UK, French, German, Spanish, Russian, Norwegian, Portuguese Brazilian (and more) translations provided
• State saving
• Hidden columns
• Dynamic creation of tables
• Ajax auto loading of data
• Custom DOM positioning
• Single column filtering
• Alternative pagination types
• Non-destructive DOM interaction
• Sorting column(s) highlighting
• Extensive plug-in support
  Sorting, type detection, API functions and pagination
• Fully themeable by CSS
• Solid documentation

JavaScript is a powerful client-side scripting language used in many modern websites and Web applications. In the hands of a skilled Web developer, JavaScript can enhance the user’s experience of the website and provide rich interactive components and features. But even though syntactically simple in nature, JavaScript is often difficult to author because of the environment it runs in: the Web browser. JavaScript’s popularity is evident in emerging technologies, such as Adobe AIR, which use it as a supported language for creating desktop-based applications.

Below, you’ll find 50 excellent tools to help you achieve various tasks involved in authoring JavaScript code. You’ll find useful tools to speed up your coding processes, including debugging tools to hunt down places where your scripts break, unit testing and validation tools to test your scripts in various situations, security vulnerability scanners and code optimization tools to make sure your scripts are light as a feather.

You’ll also find a few new and alternative JavaScript and AJAX frameworks to help you explore options beyond the big names (i.e. MooTools, jQuery, YUI, Dojo, Prototype), in addition to useful scripts to help you accomplish a host of design and development tasks related to JavaScript.

I enjoy the US show Chuck (maybe because a geeky guy gets to hang with a beautiful woman? :) and there is a 3D episode to launch their new season. Our 2009 Ajax season relaunches an old favourite meme, the Ajax loaders (e.g. ajaxload.info) with a new 3D special.

Timur Gafforov has given us Preloaders which allows you to select size, speed, and from a set of 3D spinners. Make your users wait in style! :)

JavaScipt libraries have made huge leaps and bounds in helping developers write code and develop products more quickly. jQuery is one of the most popular JavaScript frameworks, with powerful tools that improve the user’s interaction with Web applications. jQuery has an additional advantage in that it allows developers to select elements on a page using CSS-like syntax.

To help you take it up a notch, we share below some methods that can help you give visitors to your website an amazing user experience. Here are over 45 impressive jQuery plug-ins and techniques that have been recently created and that could make the development of your next website an easier and more interesting experience than the last.

Dynamic Content

1. Build A Login Form With jQuery
In this tutorial, we’ll create a sliding panel, that slides in to reveal more content, using JQuery to animate the height of the panel. In this case, we will be creating a hypothetical login for the new tutsplus area that’s coming soon.

2. Spoiler Revealer with jQuery
A simple technique that hides some content first and fades it in once a link is clicked.

3. AJAX Upload
This AJAX file upload plug-in allows users to easily upload multiple files without having to refresh the page. In addition, you can use any element to trigger the file selection window. The plug-in creates a semi-transparent file input screen over the button you specify, so when a user clicks on the button, the normal file selection window is shown. After the user selects a file, the plug-in submits the form that contains the file input to an iFrame. So it isn’t true AJAX but provides the same user experience.

4. FCBKcomplete
Give your users fancy Facebook-like dynamic inputs, with auto-complete and pre-added values.

5. Create Accessible Charts Using Canvas and jQuery
This tool is proof that you can use the <canvas> element to illustrate HTML table data. The idea is a good one: putting the data in a table allows it to remain accessible, while the chart can be shown for visual enhancement.

 

Form Manipulation

6. Radio Button and Check Box Replacement
This jQuery tool replaces radio buttons and check boxes with a more appealing display.

7. Submit a Form without a Page Refresh

8. jQuery AJAX Contact Form
Here is a quick and easy way to make a jQuery AJAX contact form with a “honeypot” to foil email bots, load success and error messages dynamically without leaving the page and provide descriptive error messages detailing why submitted values have failed validation.

9. Simple jQuery Form Validation
This jQuery form shows live form-input validators both server-side and browser-side.

 

Navigation Menus

10. jQuery Context Menu
A context menu plug-in for jQuery that features easy implementation, keyboard shortcuts, CSS styling and control methods.

Kwicks for jQuery started off as a port of the incredibly attractive MooTools framework, but has evolved into a highly customizable and versatile widget.

12. jQuery iPod-style Drilldown Menu
“We created an iPod-style drilldown menu to help users traverse hierarchical data quickly and with control. It’s especially helpful when organizing large data structures that don’t translate well into traditional dropdown or fly-out menus.”

13. jQuery File Tree
The jQuery File Tree is a configurable AJAX file-browser plug-in for jQuery. You can create a customized, fully-interactive file tree with as little as one line of JavaScript code.

14. How to Create a MooTools Home Page-Inspired Navigation Effect
In this tutorial, you’ll recreate the same effect seen in MooTools’s menu, but in jQuery!

15. CSS Sprites2
This tutorial demonstrates how to implement inline CSS Sprites2 using jQuery.

This tutorial explains how to use a slider to control the text size of an article on a page. This lets the user control exactly the size that suits them, and is also a pretty impressive feature to have on a site.

18. Pagination
Create navigational elements: when you have a large number of items, you can group them into pages and present navigational elements that allow users to move from one page to another.

19. Coda-Slider
As with the last tool, groups items together using navigational elements that allow users to move from one page to another.

20. Creating a Slick Auto-Playing Featured-Content Slider
If you love the Coda-Slider plug-in for jQuery, then you will find this plug-in very useful for displaying lots of content in a small area. This nice plug-in adds some features not found in the original Coda-Slider, such as slowly cycling through panels, auto-playing different types of custom content. An arrow indicator serves as a visual indication of which panel you are currently viewing.

21. haccordion
A simple horizontal accordion plug-in for jQuery.

 

Tabular Data and Grids

22. Table Row Checkbox Toggle
This tool generically adds a toggle function to any table row you specify based on a CSS class name. It will, by default, toggle on any check boxes within that table row.

23. Tablesorter
Tablesorter is a jQuery plug-in that turns a standard HTML table with <th> and <td> tags into a sortable table without the need for page refreshes. Tablesorter can successfully parse and sort many types of data, including linked data, in a cell.

24. TableEditor
TableEditor provides flexible in-place editing of HTML tables. User-defined handler functions can easily be dropped in to update, for example, a data source via an AJAX request.

25. Scrollable HTML Table
This JavaScript code can be used to convert ordinary HTML tables into scrollable ones.

 

Lightbox Techniques

26. Revealing Photo Slider
Learn how to create a thumbnail photo gallery, where clicking a button reveals the entire photo and more information about that photo.

28. Facebox Image and Content Viewer
Facebox is a lightweight Facebook-style Lightbox that can display images, divs, and even entirely remote pages (via AJAX) inline on a page and on demand. It uses the compact jQuery library as its engine, unlike Lightbox v2.0, which uses Prototype.

29. jQuery.popeye
jQuery.popeye is a plug-in that transforms an unordered list of images into a simple image gallery. When an image is clicked, it enlarges Lightbox-style. The images are displayed in a box with “Previous” and “Next” controls, and information about the images can be included.

 

Image Galleries and Viewers

30. Simple Controls Gallery
Simple Controls Gallery rotates and displays each image by fading it into view over the previous one, with navigation controls that pop up when the mouse hovers over the gallery. The controls allow the user to play, pause or jump to a specific image in the gallery.

31. Agile Carousel
This jQuery plug-in allows you to easily create a custom carousel. Use the jQuery UI to enable many different types of transition. The plug-in uses PHP to call images from the folder you specify. Configure many different options including controls, slide timer length, easing type, transition type and more!

 

Browser Tweaks

32. Setting Equal Heights with jQuery
A script to equalize the heights of boxes within the same container and create a tidy grid.

33. jQuery IE6 PNG Transparency Fix
Another IE6 PNG fix that uses jQuery selectors to automatically fix all PNG images on a page.

34. BGI frame
This tool helps ease the pain of dealing with IE z-index issues. You can find a demo here.

35. Fix Overflow
IE puts scroll bars inside overflowing elements, and if an element is only one line, the scroll bar will cover it. This plug-in fixes that issue.

36. Lazy Load
Lazy Load delays the loading of images below the fold on long pages. As the user scrolls down, the images are loaded as needed. Check out the demo here.

37. Maxlength
It’s a fairly common design practice to limit the number of characters a user can input in a field while giving feedback on how many spaces are left. This plug-in automates that task.

 

Animation Effects

38. Scrollable
Scrollable is a flexible and lightweight (3.9 KB) jQuery plug-in for creating scrollable content. Scrollable items can contain any HTML, such as text, images, forms, video or any combination of them. You can make items scroll horizontally or vertically and decide how many items are visible at once.

39. jQuery Fading Menu – Replacing Content
“Instead of thinking about CSS as page layout and a way to style your page when it loads, you can use in animation and change it on-the-fly to react to events that happen on your page. Take for example a menu. You can take the “click” event that happens when clicking on a menu to do lots of stuff.”

40. Build an Animated Cartoon Robot with jQuery
This effect simulates a faux 3-D animated background reminiscent of old-school side-scrolling video games (and not unlike the parallax effect). This effect is created by layering several empty divs over each other, with transparent PNGs as background images. The backgrounds are animated at different speeds using jQuery.

41. Flip

Miscellaneous

45. Date Range Picker
A rich date-range widget that uses the jQuery UI’s date picker and some additional custom interaction.

46. Sortable Lists
Unordered lists are commonly used to structure a website’s navigation. Having the ability to re-order such lists would be extremely useful. Here is a method to easily save and reload the list element order without getting lost as the page is refreshed.

47. Amazing Music Player Using Mouse Gestures and Hotkeys
Learn how to create an amazing music player, coded in XHTML and jQuery, that makes use of mouse gestures and hotkeys. You can click and drag the mouse to interact with the music player’s interface or use directional keys and the space bar instead of the mouse.

48. Script for Tracking Outbound Links in Google Analytics with jQuery
This code snippet uses Google Analytics and jQuery to automatically track outbound links. This interesting script enhances behavior by comparing the link’s domain to the current page’s domain and, if they are different, triggering the behavior. This is helpful when using a CMS or other tool that generates full URLs, including the “http://,” instead of relative ones.

<script type="text/javascript">
	$('#content a:not(.popupwindow)').filter(function() {
		var theHref = this;
		if (theHref.hostname && theHref.hostname !== location.hostname) {
			$(theHref).not(".noAutoIcon").addClass("offSite");
			$(theHref).not(".noAutoLink").attr('target','_blank').bind('click keypress', function(event) {
				var code=event.charCode || event.keyCode;
				if (!code || (code && code == 13)) {
					if(pageTracker){
						var fixedLink = this.href;
						fixedLink = fixedLink.replace(/https?:\/\/(.*)/,"$1");
						fixedLink = '/outgoing/'   fixedLink;
						pageTracker._trackPageview(fixedLink);
					};
				};
			});
		};
	});
</script>

49. jGrowl
jGrowl is a jQuery plug-in that delivers unobtrusive messages within the browser, similar to the way that OS X’s Growl Framework works.

About the author

Noura Yehia is a Web designer and blogger who can be found at Noupe and Devsnippets. If you want to connect with the author, you can follow her on Twitter.

Back on January 14, 2006, a brash, young and talented developer named John Resig put out a personal project to the OSS world and hoped it could benefit *someone*. Little did he know that 3 years later, his side project would become one of the most influential frameworks for developing JavaScript-based applications. Today, the jQuery project turns 3 years old which, considering the churn rate for open source projects, is a monumental achievement. So it makes sense that on the project’s 3rd birthday, the team has announced the release of jQuery v1.3, the latest and greatest release of jQuery which includes the new Sizzle selector engine.

Along with the inclusion of Sizzle, jQuery v1.3 includes a bevvy of new features:

• Live Events: Event delegation with a jQuery twist
• jQuery Event Overhaul: Completely rewired to simplify event handling.
• HTML Injection Rewrite: Lightning-fast HTML appending.
• Offset Rewrite: Super-quick position calculation.
• No More Browser Sniffing: Using feature detection to help jQuery last for many more years to come.

The details of the release can be found via the release notes.

In addition to that, Remy Sharp donated a new dynamic API browser to the jQuery project which makes searching the jQuery API extremely easy:

The API browser includes:

• All the latest jQuery and jQuery UI documentation.
• The ability to mark pages as favorites for those pages you keep wanting to return to.
• Syntax highlighting in the code examples
• Live running of examples within the browser
• Links to edit and experiment with the code examples

In addition, Tane Piper & Remy worked together to provide an AIR app version of the browser so you can view the API locally.

The biggest update though is that the jQuery projects (i.e. jQuery & jQuery UI) will be part of the Software Freedom Conservancy thus making the projects true non-profit endeavor and providing a number of benefits to both the project and the jQuery community including:

1. It allows the current project members to continue to manage the projects and maintain ultimate responsibility for the direction of current and future efforts.
2. It allows the projects to be considered a true non-profit efforts allowing us to be able to accept donations and contributions without incurring tremendous personal financial liability.
3. The copyright of the code will be assigned to the conservancy thus ensuring that no single person will own contributions or assets of the project.
4. It may allow corporations to write off time when an employee contributes to a project.
5. Most importantly, it ensures that the jQuery projects will always be open and free software

With so many new individuals & corporations contributing to the project, doing this became a big priority to protect the investments made by the jQuery community.

This is a lot of great news for jQuery developers and here’s wishing jQuery a happy 3rd birthday.
