In this section, we review the JavaScript written for this page. There's nothing that's really new or that pushes the boundary; it is explicitly meant to demonstrate how to use the framework we've developed in this book to create self-contained code that validates multiple forms and makes it easier for you to extend. So let's get started by reviewing the basic template.
The following is the basic template we've been using. A standard namespacing technique that extends the App namespace with a Form class will contain all of our functionality.
var App = window.App || {};
App.Form = (function(window, document, $){
'use strict';
var _defaults = {
'element': 'form',
'name': 'Form'
};
function Form(options) {
// Customizes the options by merging them with whatever is passed in
this.options = $.extend({}, _defaults, options);
this.init();
}
