A lightweight emoji system for textarea and input fields
Rainbow can be simply invoked by calling it against a DOM object and it will monitor changes and replace keystrokes to become emoji (ie :) becomes 🙂)
Simply include this script in your footer (After jQuery has loaded) (Or better still, using Cooker at https://github.com/genericmilk/cooker 😉 add it to the /resources/js/libraries folder)
Attach a Rainbow instance to an input by invoking it using the following:
r.attach($('textarea.comment'));
Rainbow will now watch textarea.comment for changes and will respond to ascii emoji symbols with the emoji counterpart.
If you'd rather parse an input yourself once rather than attaching a keyup listener, You can use the following
r.parse($('textarea.comment'));
This will call the parse event once and process the text in textarea.comment
