Given the Object-Oriented nature of the MooTools framework, code repetition is something that is long forgotten (or should be) in the scripts your write. With the avoidance of code repetition comes code reusability, which results in your website being easier to read, extend and maintain, and your scripts smaller in size.
At this point there’s no doubt in anyone’s mind that DRY is a principle we should stick to. However, let’s examine how to achieve this in the right way.
As I release my latest MooTools plugin, PlaceholderInput, that adds support for input placeholders, I decided to explain my solution, and what others are available.
An example of my implementation is seen on the Devthought sidebar, right next to this post. I’ll analyze next the different solutions that have been offered for this problem, and the upsides and downsides each has.
In my unstoppable pursuit of the best user experience scripting techniques, I decided to bring the famous BSOD to the web developers’ world.
I came up with a document describing the projections, possibilities and capabilities of my creation, which you can access here. It includes different scenarios and variations of this implementation.
