CODE: AJAX-02-02 DURATION: 2 DAY/S
In this two day course Building Dynamic Web Applications with Ajax course, you will learn the ins and outs of the various flavours of Ajax. You will also acquire the skills necessary to apply Ajax to your web application development, whether you're hand-coding or using your JavaScript framework of choice.
LEARN HOW TO:
- use the native XMLHttpRequest object and it’s ActiveX counterpart,
- write concise and expressive code by using JavaScript frameworks (jQuery, Prototype, YUI, dojo, ExtJS),
- apply asynchronous and event-driven programming paradigms,
- handle all types of ajax response (XML, HTML, text, JavaScript, JSON),
- leverage the power of HTTP and REST,
- easily post form data,
- stay unobtrusive,
- gracefully handle errors and flaky connections, and
- use JSONP, iFrames or flash to deal with ajax’s inherent limitations (SOP, file uploads).
