A basic pattern for jQuery plugins

lol.js

(function($) {
	$.fn.lol = function() {
		var scope = function($this) {
			var f = {
				/**
				 * The "constructor"
				 */
				init : function() {
					console.log('init');

					// Hook events up to functions in the f scope.
					$this.click(f.events.click);
					$this.bind('mycustomevent', f.events.customEvent);
				},

				/**
				 * Sample function - Sets the background color of $this.
				 * 
				 * @param {String} color The color to set.
				 */
				setBg : function(color) {
					console.log('setBg(' + color + ')');

					$this.css('background-color', color);
				},

				events : {
					/**
					 * Register the click, changing the background color.
					 */
					click : function() {
						console.log('click');

						f.setBg('green');
					},

					/**
					 * Log some custom event.
					 */
					customEvent : function() {
						console.log('custom event!');
					}
				}
			}

			f.init();
		}

		return this.each(function() {
			scope($(this));
		});
	};
}(jQuery));
