is.js

Check your data against regular expressions or known keywords (see Keyword section). Different versions for different platforms are availible.

Currently these plugins are stable:

• jQuery
• Vanilla JavaScript (untested)
• Node.js Module (untested)

I wrote a really short blog post about the project a while ago, which can be read at rthor.is/javascript/cross-plugin-javascript-project-isjs. Note that some code examples are out of date.

Change Log

0.1.2 JUNE 14, 2013

• phone has become an object so calling it requires a two letter ISO 3166 country code. For example validating Icelandic phone numbers in vanilla JS is now done thusly: is('+354 000-0000', 'phone:is'). In addition a few more countries were added.

• cc - pretty much same thing happend as with the phone thing.

0.1.1 May 24, 2013

• First stable release
