There are some great JavaScript testing frameworks out there. Many only work from within a browser. Most don’t support testing asynchronous code like event callbacks. Some have syntax that’s hard for JS developers or IDEs to understand.

Jasmine is a JavaScript testing framework. It’s heavily influenced by, and borrows the best parts of, ScrewUnit, JSSpec, JSpec, and of course RSpec. Jasmine is not tied to any browser, framework, platform, or host language. It work anywhere JavaScript can run, including browsers, servers, phones, etc.

When you publish something online, there are not that many ways to determine whether people like what you have to say. Comments, the cornerstone of blogging, are too demanding, and users often prefer not to post one.

If you’ve dropped by Behance, you’ve probably noticed their appreciate badge, which is a neat solution to this exact problem. With it people share their appreciation for somebody’s work. Tutorialzine taught us how to implement An AJAX Click to Appreciate Badge, which you can include in every page of your website with a bit of jQuery magic.

One of the more interesting and fun aspects of iPad usage is the ability to effect change in a webpage by swiping a finger across the screen of the iPad. For example, swiping to the left to navigate to the next page in a series of pages, or swiping to display the next image in a series of images. For iPad users, these actions are intuitive and natural.

However, for those who compose webpages, adding touch detection to a page can be a challenging and difficult process. No more. The information presented on Padilicious: Add Finger-Swipe Support to Webpages, will make it easy to add touch sensing to your pages, requiring only a minimum of JavaScript coding on your part.

AddyOsmani is going to teach us how to create a useful hover-based user interface using jQuery, CSS3, HTML5 and @font-face. Why a hover-based interface? With the popularity of touch-based web applications simplifying the way that people can use sites on mobile devices, there’s room for us to look into ways of making it even easier for people to use sites in desktop-based browsers too.

WanderWall achieves that and what it could easily be used for a portfolio or business site but the concepts we’ll learn could certainly be used to expand the idea further.

jQuery Image Scroller Plugin creates a scrollable interface to scroll over a large image in a smaller area. The idea is that we have a container with a fixed height and width, an image that is taller than the container, and a container for the thumbnail of that image.

Once the plugin is applied, there is a span with a class of indicator appended to the small preview area which represents the area you can drag up and down.
