It’s not often that new user interface conventions are born – or popularized. Even less so within the realm of web development. I’d argue that Sparklines and Lightbox are two of the best examples of UI conventions that were popularized on the web.
Recently Maxime Haineault announced a simple jQuery plugin for inputting a new time of day called jQuery.timepickr.js. Its principles are very similar to jQuery itself: Get users to input the time as simply as possible with as little input as possible.
To achieve this he made a “two click” time picker. The first click is within the time field. This activates the display and allows the user to choose the time – all of which is done by moving the mouse over the times that you desire. The final click is anywhere – filling in the time that was chosen. It’s hard to explain, you simply have to try it.
One thing that you’ll notice using it is that it’s fast. Very fast. I’d argue much faster than clicking into the input area, moving to the keyboard for entering the time, typing the time, then moving back to mouse.
But not only is it faster, but it’s also quite intuitive – which is rather rare for something that utilizes a completely new user interface convention.
A nice extra point is that the input is completely styled using the jQuery UI style conventions – which means that you’ll be able to customize it completely with the jQuery UI Themeroller.
