AJAX Inleiding

AJAX is designed to update certain parts of a web page without reloading the entire page.

What is AJAX?

AJAX = Asynchronous JavaScript and XML (Asynchronous JavaScript and XML).

AJAX is a technology for creating fast and dynamic web pages.

By exchanging a small amount of data with the server in the background, AJAX allows web pages to be updated asynchronously. This means that certain parts of the web page can be updated without reloading the entire web page.

Typical web pages (not using AJAX) must reload the entire page if the content changes.

Typical use cases for AJAX include: Google Maps, Tencent Weibo, Youku Videos, etc.

How AJAX works

AJAX is based on Internet standards

AJAX is based on Internet standards and uses the following technology combination:

  • XMLHttpRequest object (used for asynchronous data interaction with the server)
  • JavaScript/DOM (displays/retrieves information)
  • CSS (sets the style of data)
  • XML (often used as a data transmission format)

Tip:AJAX applications are independent of browsers and platforms!

Google Search Suggest (Google Suggest)

With the release of Google Search Suggest in 2005, AJAX began to gain popularity.

Google Search suggests using AJAX to create highly dynamic web interfaces: when you type content into Google's search box, JavaScript sends characters to the server, and the server returns a list of suggestions.

In onze ASP handleidingen demonstreren we hoe AJAX een deel van de pagina kan bijwerken zonder de hele pagina opnieuw te laden. We zullen ASP gebruiken om serverkant code te schrijven.
