AJAX has crept its way into websites in the last few years. Over time, it has slowly become the best solution for creating responsive, user-friendly, and dynamic websites. But you may be wondering: what is AJAX (in WordPress) exactly?

👉 In simple terms, AJAX is a mix of CSS, HTML, and JavaScript that enables you to update your web page without needing to reload the entire site.

In WordPress, AJAX is typically used to allow users to get immediate feedback on the actions they’re performing without having to reload the page they’re on. This is most useful in the admin panel, where you’d typically work on a post – adjusting a number of details – without having to save the page in between the changes and have it reload to store your changes.

What is AJAX in WordPress and how does AJAX work?

AJAX is an acronym for Asynchronous JavaScript and XML.

  • “A” stands for “asynchronous,” refers to how the different information on the page doesn’t load simultaneously.
  • “J” stands for JavaScript. This component plays an instrumental role in asynchronous updating because it enables you to add dynamic content to your website.
  • “X” stands for XML. If you’re familiar with HTML, then XML should be simple to learn because it’s a similar markup language. XML enables you to store data in a specific format without having to rely on a system or software to process it completely.

How does AJAX work in WordPress? ⚙️

AJAX serves as the bridge between the server and your website. As such, the core of this technology is a data exchange that goes as follows:

The bulk of the communication between a website’s user and the website is done through HTTP requests. Most commonly, those requests are being sent back and forth on each page reload. AJAX speeds the process up by using JavaScript to send those requests asynchronously without triggering the page reload. The server can receive, process, and return a response without needing that reload. Finally, the user’s browser uses JavaScript to process the returned data and update the page content accordingly.

Luckily, WordPress natively supports AJAX, and the technology is built into it by default. If you want to add more AJAX functions – say an AJAX search – then doing so shouldn’t be difficult.

What are the benefits of using AJAX in WordPress?

Whether you’re starting a personal blog on WordPress or looking to create a more dynamic platform, AJAX is a convenient tool to have on hand. Take a look at the advantages below to see just how beneficial AJAX is:

✅ AJAX makes WordPress sites run faster due to its asynchronous nature

✅ AJAX updates immediately and allows users to see any changes instantly

✅ AJAX maximizes the hosting bandwidth because it only sends the core data back and forth without unneeded interface elements or other pieces of info

Conclusion 🧐

Let’s do a quick recap of the question: what is AJAX in WordPress? It’s a technology that allows you to update your content without needing to reload the page. Plus, it’s easy to use in WordPress because it’s there by default.
