jQuery Increment Plugin

The latest version of the jQuery Increment plugin (v. 0.6) now supports use of the mousewheel plugin by Brandon Aaron to increment/decrement numeric input values. Ensure scripts are loaded in the proper order (jquery » mousewheel » increment).

jQuery Increment Plugin

Inspired by this article on css-tricks.com, I decided to release a plugin dedicated solely to quick keyboard-based manipulation of numeric values in HTML input fields. It’s called Increment.

» See the Demo

Simply assign the set of inputs you wish to attach this behavior to:
$('input.hours').increment();
And let your fingers do the walking: use the up arrow to increment values, down arrow to decrement. Hold down shift for greater increments (maxIncrement), Ctrl/Cmd for smaller ones (minIncrement).

Define custom options for Increment easily:
$('input.hours').increment({ increment: 10 });
See plugin script comments for full list of options.

Use Cases: Time sheet applications (how I came to develop this), Order / Requisition forms, anywhere multiple numeric form inputs are needed.
