AJAX full form is Asynchronous JavaScript and XML. It is a web development technique for creating interactive web applications. AJAX allows web applications to send and receive data asynchronously from the server. This means that the web application can continue to function even if the user is waiting for a response from the server.
Life Cycle of AJAX
AJAX is a technique that allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. This avoids the need to reload the entire page.
The typical AJAX lifecycle goes something like this:
- The user initiates an AJAX request by clicking on a link or button.
- The browser sends a request to the server.
- The server processes the request and sends back a response.
- The browser updates the page based on the response.
- The user interacts with the updated page.
