Ajax Basics And Framework

  1. 1. Ajax Basics and Framework K.shivaprasad 9092696592
  2. 2. What is Ajax? Ajax(Asynchronous Java Script and Xml)is a group of interrelated web development techniques used on the client-side to create interactive web applications
  3. 3. More about Ajax <ul><li>With ajax web application can retrieve data from the server asynchronously in the background with out interfering with the display and behavior of the existing page. </li></ul><ul><li>Data are usually retrieved using the XMLHttpRequest object </li></ul><ul><li>Ajax uses the combination of HTML and CSS to markup and style information </li></ul>
  4. 4. Continue.. <ul><li>The Dom is accesed with javascript to dynamically displays and to allow the user to interact with the information presented. </li></ul><ul><li>Java script and the XMLHttpRequest object provide a method for exchaning data asynchronously between browser and server to avoid full page reload. </li></ul>
  5. 5. Technologies in Ajax. <ul><li>HTML or XHTML and css for presentation </li></ul><ul><li>The Dcument Object Model for dynamicallydisplay of and interaction with data. </li></ul><ul><li>XML and XSLT for the interchange and manipulation and Display of date respectively </li></ul><ul><li>The XMLHttpRequest object for Asynchronous communication </li></ul><ul><li>Javascript to bring these technologies together. </li></ul>
  6. 6. Ajax Uses. <ul><li>Using a Ajax web application an request may the context that needs to be updated thus draftically reducing the bandwidth usage and load time. </li></ul><ul><li>The use of asynchronous requests allows the clints web browser UI to be more interactive and to respond quickly to inputs and sections of pages can also be reloaded individually. </li></ul><ul><li>The use of Ajx can reduce connection to the server,since scripts and style only here to be requested once. </li></ul>
  7. 7. Draw Backs <ul><li>Owing to their dynamic nature.Ajax interfaces are often harder to develop when comared to static pages </li></ul><ul><li>Pages dynamically created using successive Ajax requests do not automatically register themselves with the browsers history engine. </li></ul><ul><li>Dynamic web page updates also make ifdifficult for a user to bookmark a particular state of application. </li></ul><ul><li>Because most web Crawlers donot execute Javascript code. </li></ul>
  8. 8. Drawbacks Continue.. <ul><li>The same origin policy prevents some Ajax techniques from being used across domains. </li></ul><ul><li>Like other web technologies Ajax has its own set of changes that developers must address. </li></ul><ul><li>Developers familar with other web technologies may have to learn new testing and coding methods to write secure Ajax application. </li></ul>
