jquery-mobile-960

jquery-mobile-960 (GitHub: jeromeetienne / jquery-mobile-960)
by Jerome Etienne is a port of 960 grid to jQuery Mobile. By combining
960.gs with jQuery Mobile the author aims to offer more flexible layout options, which makes
supporting tablets easier:

jQuery mobile layout is currently rather raw. They only split the width in even parts, providing little controls to the designer. It uses an custom API with names ending with a, b, c or d, ui-block-a for example. Not the classic grid-4 or span-3, so it feel awkward. [...] 960 grids are flexible and well known. So i used ported 960 grids to see if it helps.

Easy WebSocket

Easy WebSocket (GitHub: jeromeetienne / EasyWebsocket, MIT
License) also by Jerome Etienne is an effort to remove servers from the
WebSocket equation. It appears to use iframes and a small Python App
Engine script to make accessing resources as easy as this:

  var socket = new EasyWebSocket('ws://example.com/resource');

  socket.onopen = function() {
    socket.send('hello world.')
  }

  socket.onmessage = function(event) {
    alert('received: ' + event.data);
  }

So technically it still depends on a server, but it could make the lives
of front-end developers simpler who aren't used to messing around with
server-side code.

mapKey

mapKey (GitHub: pixelmatrix / mapkey, MIT License) by Josh Pyles is a jQuery keyboard shortcut plugin that has
aliases for a lot of keys. Rather than working out the key codes for
arrow keys, left and up can be used instead:

$.mapKey('down', function() {
  // Keyboard shortcut event support goes here
});

I always try to add keyboard shortcuts to my apps, so rather than my
hokey homebrew keyboard code I might give this a try. One thing to
remember when supporting hotkeys is to be specific -- if a letter key is
pressed should this still trigger when the shift or metakeys are held
down?

bValidator

bValidator is a client-side validation library with extensive form control support and configuration
options. Custom attributes can be used to define the required
validations on a field:

This can be changed when setting up the plugin:

('#form').bValidator({ validateActionsAttr: 'class' })
