WHAT EXACTLY IS AJAX?
Ajax == Asynchronous JavaScript and XML
Ajax is really a set of technologies working together:
XHTML and CSS for markup DOM for display and interaction XML and XSLT for data interchange & manipulation JSON for marshalling objects XMLHttpRequest for asynchronous communication JavaScript for tying it all together
Allows us to load data from the server without a browser page refresh
DEMO
Ajax
JQUERY• Javascript is HARD• jQuery is a Javascript library that makes Javascript easier• Simplifies DOM spelunking• Handles browser differences• Provides a key shortcut “$”
•Download from jquery.com• The jQuery library has a full suite of functions and methods for AJAX capabilities. •Hosted on CDN
JQUERY SYNTAX
• $(selector).action()
• $ references jQuery; (selector) queries the DOM element or elements; and .action() performs an action on the element.• Examples of jQuery syntax:
◾$(this).hide() hides the current element.◾$("p").hide() hides all paragraphs.◾$("p.wow").hide() hides all paragraphs of the class "wow".◾$("#wow").hide() hides an element with the id of "wow".

KNOCKOUT.JS
•MVVM Support•Declarative Bindings•Observables• Live Data• Supported in every widget• It’s Optional
WHAT IS MVVM?• Model• The Model encapsulates the domain model, business logic and may
include data access. For Example a Customer object contains properties for Name and Address.
• View• The view is the application’s User Interface (UI). It defines the
appearance of visual elements and controls such as text boxes and buttons.
• View Model• The view model is responsible for holding application state, handling
presentation logic and exposing application data and operations (commands) to the view such as LoadCustomers and SaveCustomers. It acts as the intermediary between the view and model.
3 STEPS FOR USING KNOCKOUT WITH WIJMO
• 1. Add references to the latest jQuery dependencies, Wijmo widgets, Knockout .js file, and KO extension library for Wijmo.
• 2. Create the ViewModel and View: add JavaScript to define the data and behavior of the UI, and add markup to create the View—the visual, interactive UI.
• 3. Bind the Wijmo widget(s) to the ViewModel and activate KO.
