What is AJAX?

Last modified: February 23, 2020

Asynchronous JavaScript and XML (AJAX) is a set of techniques used within web development that enables a website page to communicate with the hosting server without the need to reload the page. This allows for applications on a page to send and receive data with the server, without there being a drop in website performance.

The X in AJAX is supposed to stand for XML. However, it is not necessary to utilize XML when exchanging data, instead JSON or plain text can be utilized. However, for the purposes of standardizing terms, XML is the standard.
The Asynchronous aspect of this technique is meant to symbolize that the functions are programmed with AJAX are independent of the website’s loading.

A common misconception is that AJAX is a programming language. It is not. It is actually a combination of a browser built-in XMLHttpRequest object. This requests data from the host server. It also uses JavaScript and HTML DOM to display or use data that the user has inputted.

AJAX can be in WordPress websites for many functions. It can be seen in the post edit screen for webmasters. While you’re changing a category, adding a tag or changing certain aspects of the page, you’re utilizing AJAX to make those changes.

Another common example of how AJAX is used in your dashboard is when you manage comments. You can approve, mark as spam or delete comments with ease and without loading the entire page.

Your website’s visitors might notice AJAX on your website if you utilize filters that quickly remove potential products from a shop page without reloading the page. Or if there is a sort function that also doesn’t reload the page.

There are certain benefits of AJAX on your WordPress website. For instance, it allows you to collect information from visitors and present them with new information without the need to compromise website performance. It is also easy to utilize and quick to problem solve with.
