ASP AJAX

This lesson is part of ASP · All levels

Summary

AJAX allows web pages to send or load data to the server without refreshing the entire page, making the user experience more responsive. In Classic ASP, this technology is run with XMLHttpRequest objects in a browser that sends a request to the .asp file and then receives a response in the form of HTML, XML, or JSON. Since ASP works on a server, AJAX is ideal for calling scripts that process data.

Key points

AJAX updates some pages without reloading the entire document.
Asynchronous requests use XMLHttpRequest or Fetch in JavaScript.
The Classic ASP script is quite responsive to data without a full page layout.
AJAX responses are generally in the form of JSON or partial HTML.
