  2. Ajax Technology

  6. Ajax Example
    This example is simple one to understand Ajax with JSP. The objective of the example is to display the current date of the server on the page on each key up event by the user without refreshing the current page. This example also shows the key value entered by the user in the input text field along with the current date and time.
  7. Ajax Frameworks Types
    There are two types of Ajax based frameworks used in the web programming nowadays: Server-side Framework and Client-side Framework. Server-side framework is installed inside the server while Client-side framework entertains the user?s browser to access the web. Similarly, the code executed on the Web server is considered as Serverside code while if executed on the user?s browser is known as Client-side Framework.
