Ajax Using JSP with prototype.js
Download as PPT, PDF3 likes1,893 views
AJAX is a group of technologies used to create asynchronous web applications. It allows for updating parts of a web page without reloading the entire page. This improves responsiveness and allows for more dynamic interactions. Some key benefits of AJAX include more responsive interfaces, ability to update small parts of pages individually, and reduced waiting times. While it increases development complexity, AJAX is widely used in applications that involve heavy server requests, need to display large amounts of data sequentially, or where user interaction is frequent. Common frameworks for implementing AJAX include Prototype.js and Dojo Toolkit. Many large websites use AJAX, including Google Maps, Gmail, and Facebook.

- 2. Introduction What is AJAX ? AJAX Request-Response Cycle. Working of AJAX Applications of AJAX
- 3. WHAT IS AJAX? Asynchronous Java script And XML. It is not itself a technology but a group pf technologies such as HTML Java script CSS XML DOM (document object model)
- 5. How AJAX is Different?
- 8. Why we Use AJAX / Benefits of AJAX interface is much more responsive . small part of the page is transferred at a time . classic web application -content only – what is between the <body> tags -only one connection thread . With AJAX, you only have to load the basic scripts and CSS files, and request the rest as content, through multiple connections . Waiting time is reduced .
- 9. Advantages of AJAX Time saving Maximum Usage of Bandwidth Browser and platform independent applications
- 10. Disadvantage of AJAX. AJAX-powered application can increase development time and costs . existing page conflicts -used to navigate and create bookmarks in modern browsers . The biggest concern with AJAX is accessibility . Turn off JavaScript support -fail-safe solution exists for those users . Actual XMLHttpRequest object itself-only use it to access information from the host that served the initial page .
- 11. Why we use AJAX in our project ? Involves heavy server requests . With multiple web forms that submit data to the server . heavy traffic . Display large amounts of data in a sequential manner without refreshing the entire page . Users interact frequently . Application response time is a concern Loading times have to be as short as possible
- 12. Where not to use AJAX Plain, static HTML pages . Application must be accessed by older browsers . Loading times - bandwidth usage is not a primary concern . Cost - time factors are paramount for the delivery of your project and your . Development team cannot afford to build a complex AJAX framework .
- 13. AJAX Using Jsp Introduction -rapidly develop , easily maintain, information-rich, dynamic Web pages. How to use Ajax in JSP 1. Ajax framework for java 2. Simple Ajax script for JSP
- 14. Ajax framework Using prototype.js Dojotoolkit Rico framework
- 15. Using Prototype.js http://prototypejs.org/download <script type="text/javascript" src="/path/to/prototype.js"></script> Create one jsp file. like ajax3.jsp
- 17. Second jsp file hello1.jsp
- 20. Supported Web Browser The XMLHttpRequest object is supported Internet Explorer 5.0+ Safari 1.2 Mozilla 1.0 / Firefox Opera 8+ Google Chrome Netscape 7.
