An Up/Down control in jQuery
Make machines do your bidding with JavaScript. Check out The Little Book of JavaScript!
Recently, I needed to write an up/down selector – you know the sort, it’s where you select a number by clicking on an up or down arrow. Since they can be useful for other things besides numbers, I gave it the plugin treatment.
Most of the information about the plugin can be found in its documentation page.
Also available is a slightly beefier styled and animated demo of the plugin.
If you’re just interested in the plugin itself, you can find it here.
Attaching data to elements in jQuery
Bring on the scripting! Check out The Little Book of JavaScript!
This morning, I found out about a very useful jQuery function going by the unassuming name of data. This fantastic little beast creates a data store for an element, and lets you store just about anything in there.
One of the ways in which this can be used is to attach functions to an element, and using them when required. To demonstrate the usefulness of this feature, I wrote two versions of a simple validation system. In one, we use the data function to assign one or more validators to an input box [Example 1: using $(x).data()]. In the other, we iterate over the inputs and check them against validators as needed [Example 2: not using $(x).data()]. Continue reading “Attaching data to elements in jQuery”
Generics in Java and C#
Today I was writing some interceptors in Java, and I wanted to be able to filter the input based on whether it implemented a given interface or otherwise. Class<?> exposes a very handy isAssignableFrom method for this, but it doesn’t look very nice, so I tried to go for something a bit neater, like:
1: Feature.<TargetFeature>isImplementedBy(interceptedInstance);
Neat, and much more readable. I didn’t quite make it there, but got close enough for my purposes, and had some (very little) deeper knowledge of generics inflicted upon me for my sins.

Joining the “IE6: Do NOT Want!” Campaign
The people of the web are revolting against IE6! (at last). While many web developers and designers have been complaining about Internet Explorer 6 for ages, more people are now making a concerted effort to ease users away from this museum piece. There’s even a wiki about this worthy cause.
Simone Chiaretta wrote a great article about this campaign at CodeClimber, with instructions on including Vincent Hasselgård‘s IE6 warning. Joe Levi also created a great variation of this to scare IE6 users with 🙂
Vive la revolution!

Behaviour driven development on user interfaces with Automation peer
Testing user interfaces is usually a pain in the butt. No matter how cool your UI is, it will often boil down to a brain-cell killing process clicking the same buttons over and over again. Thanks to the Geek Gods of .Net though, there are ways to automate this, and it’s not even that tough to do.
In this post, we’re going to use Automation peers to expose a button to a unit test, and have the test start the application, click the button, and confirm that the button does what it’s meant to do. We’re going to use MbUnit to write the test, and NBehave to make the tests nice and clear.

VS and SVN – Ignoring user specific files
Visual studio tends to create files that you don’t usually want to keep under source control, such as generated files, user option files, and so on. To avoid having to clean up every time you try to Add files, you can tell TortoiseSVN to ignore certain file name patterns. The following is what I usually use:
**/bin bin **/obj obj *.suo
You can set these patterns in the “Global ignore pattern” text box in the main screen of the TortoiseSVN settings dialog.
