// Creates a default Entropizer meter inside #meter and watches the first password field on the // page by default $('#meter').entropizer();

// Create an Entropizer meter using custom options $('#meter').entropizer({  	// The input field to watch: any selector, DOM element or jQuery instance 	// Default: 'input[type=password]:first' 	target: '#pwd', 	 	// The event(s) upon which to update the meter UI 	// Default: 'keydown keyup' 	on: 'keydown',  	// Used to calculate the percentage of the bar to fill (see map function below) 	// Default: 100 	maximum: 80,  	// An array of ranges to use when classifying password strength. Used internally by default map 	// function and can be used publicly via $.entropizer.classify(value, buckets). Properties 	// 'min' and 'max' are used to calculate which bucket to use - upon finding a match, an object 	// containing all the other properties is returned, e.g. below, a value of 42 returns 	// { message: ':)' } 	// Default: 4 ranges with strength and color properties (see source for values) 	buckets: [ 		{ max: 40, message: ':(' }, 		{ min: 40, max: 60, message: ':)' }, 		{ min: 60, message: ':D' } 	],  	// Either an Entropizer engine options object or an Entropizer instance 	// Default: a new Entropizer instance with default settings 	engine: { 		classes: ['lowercase', 'uppercase', 'numeric'] 	},  	// A callback controlling UI creation - takes a jQuery instance representing the container 	// and returns an object containing UI components for access in update and destroy 	// Default: creates a track element (the bar background), a bar element and a text element 	create: function(container) { 		var bar = $('<div>').appendTo(container); 		return { foo: bar }; 	}, 	 	// A callback controlling UI cleanup - takes the UI object created by create 	// Default: removes the track, bar and text elements 	destroy: function(ui) { 		ui.foo.remove(); 	},  	// A callback that maps the raw entropy value to an object passed to update. First argument is 	// the number of bits of entropy, second argument is an object containing all properties on 	// the options object apart from target, on, engine and the callbacks (i.e. by default, just 	// maximum and buckets) 	// Default: uses maximum and buckets above to return an object with entropy, percent, strength 	// and color properties 	map: function(entropy, mapOptions) { 		return $.extend({ entropy: entropy }, $.entropizer.classify(entropy, mapOptions.buckets)); 	},  	// A callback controlling UI updates - takes the data returned by map and the ui object 	// Default: updates the width and background color of the bar, and displays the number of bits 	update: function(data, ui) { 		ui.foo.text(data.entropy.toFixed(0) + ' ' + data.message); 	} });
