Course Outline
AJAX (Asynchronous Java and XML) has emerged as a powerful platform for building web applications with extensive client-side interactivity.
Unlike older approaches, which require reloading of the entire page with every postback, AJAX uses the JavaScript DOM, the XMLHttpRequest object, XML, and CSS to download and display just the content that needs to change.
Course Content
The course will contain a substantial amount of Hands-On work. Delegates will be introduced to topics during theory sessions and these will be followed by lab exercises relating to the topic. Exercises will reflect commercial scenarios.
This course has been developed for real-world, commercial scenarios by our expert instructors. See below for detailed syllabus. If you have a technical question, please email sales@jbinternational.co.uk
