Question

Explain Ajax callback function.

Answer 1

Following are steps carried out during Ajax callback:

1. Client browser sends a request message to Server.
2. The user is free to do anything other than waiting for the response as the request call is asynchronous in nature.
3. The server receives the message and processes the page for which Ajax callback is called.
4. The response is sent to the browser as a JavaScript code string that gets executed in the browser.
