/* Placeholders plugin for jQuery
*  Use this to provide a graceful fallback for browsers not supporting the html5 placeholder attribute
*
*  Usage:
*  jQuery('form').placeholders(); // if the user's browser do not support placeholder, it implements a fallback
*
*  You can also specify some options:
*  jQuery('form').placeholders({
*    placeholderAttr: "title",           // specify the attribute to get placeholder value from (default: 'placeholder')
*    placeholderedClass: "custom-class"  // the class added to the input element when its value is a placeholder (default 'placeholdered')

Experimenting with a Rails-like client-side JavaScript Model

Backbone.js is awesome, but sometimes you just don't need the full MVC stack.

This is just a random experiment to come up with something simple and familiar to Rails developers, to allow something like:

// create a Post model
var Post = jjj.Model({

Usage:

the $query (aliased with $q) object exposes two methods: first() and all(). Both take a selector string as the first argument and, optionally, a context element as the second.

$q.first(".foo"); // => first element of class `foo`
$q.all(".foo");   // => array (yes, not NodeList) of all elements of class `foo`

var elem = $q.first("p");

ClosedStruct

A stupidly simple implementation of a kind of "sorta immutable" struct that can be instantiated as conveniently as an OpenStruct but after instantiation it doesn't let me (easily) add fields or mutate them:

guy = ClosedStruct.new( name: "John", age: 23 )

# readers:
guy.name             #=> "John"
guy.age #=> 23
