At.js – AutoCompletion Library for Web Applications

At.js is an autocompletion library to autocomplete mentions, smileys etc. just like on Github or Twitter. It supports HTML5 contentEditable elements. You can listen to any character and not just ‘@’, set up multiple listeners for different characters with different behavior and data.

Listener events can be bound to multiple inputors. Keyboard controls are supported in addition to mouse. You can use custom data handlers and template renderers using a group of configurable callbacks.
