jQuery Mobile Helps to make sites work well in a mobile environment, although it is not the only option Takes care of the layout and the transition between pages of a site to make the site more like a mobile app Available as a download or through a Content Delivery Network (CDN) Download from get the latest stable versionhttp://jquerymobile.com

Activity 35 (Basic) Test Page for jQuery Mobile Test Page This is some nice content. Footer content

Page link in jQueryMobile Links to pages in current site use AJAX by default. We could set it not to use AJAX Links to something outside current site do not use AJAX We will study AJAX later, but when it is used, an animation will be displayed before the linked page is loaded. The animation serves as transition to make the current page out of view Types of transition available: fade (default), flip, flow, none, pop, turn, slide, slidedown, slideup, slidefade

Linking without AJAX Links outside the site (to another domain) Links defined with rel=“external” attribute Links defined with the data-ajax=“false” attribute Links defined with a target attribute

Activity 36 (Ways of Loading links) Test Page for jQuery Mobile Link Page Load the test page (default behavior) Load test page (with turn transition effect) Load the test page (data-ajax = false) Load the test page (rel = external) Load the test page (in new tab) jQueryMobile page

Activity 37 (Navigation bar & buttons) Adding Navigation Tool bars Go Back My Buttons Go Forward Assalamualaykum/ Salam Sejahtera! Line 2 Line 3 Sweet Home Have a nice time!

AJAX Before this, we have been focusing on changing the behaviors, look and feel of pages, and little validation of forms Asynchronous JavaScript and XML (AJAX) JavaScript feature to allow pages to obtain and work with data to and from the server Examples of data are such as flight times, prices, etc. Three (3) primary components in a web application: Display, Behavior, and Data JavaScript interact with a database or server through AJAX or web services

AJAX Basics AJX-based applications send request from the web browser to the web server in the background (asynchronously) to make the pages more responsive to the user The actual process of sending a request and handling the response involves the fundamental AJAX object called, XMLHttpRequest jQuery includes a built-in function called $.ajax() to simplify the process of sending and receiving data XML contains extraneous information JSON (JacaScript Object Notation) provides a lightweight way to exchange data over AJAX - without X!

AJAX Architecture

XML vs JSON Mohd Soperi Mohd “person”: { “firstname” : “Mohd Soperi”, “lastname” : “Mohd Zahid”, “ Address” : { “primary ” : }, “twitter” : } XML version JSON version – represented in less extraneous information, but clarity is still maintained

Using AJAX Instantiate XMLHttpRequest object Build a request by specifying the request method (GET, POST, HEAD, etc), the URL to which request will be sent, and a true/false value indicating whether the request will asynchronous or synchronous Send requests to the web server synchronously or synchronously For asynchronous, check response status using onreadystatechange event to trigger code that checks the event’s readyState property (values given in next slide) AJAX response received (status value 200 = success) Process AJAX response

Synchronous Web interaction

Asynchronous Web interaction

readyState property values ValueDescription 0Uninitialized. Open but has yet to be called 1Open. Initialized but not yet sent 2Sent. The request has been sent 3Receiving. The HTTP response headers have been received, but the response body has not yet been completely received 4Loaded has been fully received

Activity 38 (A Simple AJAX program) Let AJAX change this text Change Content function loadDoc() { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (xhttp.readyState == 4 && xhttp.status == 200) { document.getElementById("demo").innerHTML = xhttp.responseText; } xhttp.open("GET", "ajax_info.txt", true); xhttp.send(); }

Getting XML data Retrieve data from XML file Status: Status text: Response: Get XML data function loadDoc(url) { var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (xhttp.readyState == 4 && xhttp.status == 200) { document.getElementById('A1').innerHTML = xhttp.status; document.getElementById('A2').innerHTML = xhttp.statusText; document.getElementById('A3').innerHTML = xhttp.responseText; } xhttp.open("GET", url, true); xhttp.send(); }

AJAX and jQuery jQuery offers several functions for working data such as.load(),.post(), and.getJSON() The.ajax() function can be used to set several parameters such as HTTP method, time-out, what to do when an error occurs, etc.

Activity 40 AJAX, jQuery and JSON Test $(document).ready(function() { $("#driver").click(function(event){ $.getJSON('test.json', function(jd) { $('#stage').html(' Name: ' + jd.name + ' '); $('#stage').append(' Age : ' + jd.age+ ' '); $('#stage').append(' Sex: ' + jd.sex+ ' '); }); Click on the button to load data from json file: STAGE
