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 50 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

7. Submit a Form without a Page Refresh

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.

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

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.

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

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

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.

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
