Using AJAX For an Amazing User Experience

As we dive deeper into the world of web and software development, you may come across the term AJAX. Don't let the name fool you! In web development, it has nothing to do with cleaning products, ancient warriors, or football teams. 

So what exactly is AJAX? Is it a programming language, a software platform, or a web application? Actually, it's none of those things. Instead, AJAX (short for Asynchronous JavaScript and XML) is a set of techniques that allow websites to communicate with a server and update parts of the page without reloading the entire thing.

If you have ever wondered how Google Suggest comes up with a list of suggestions to complete your query, you can thank AJAX. Google Suggest works with AJAX by using Javascript to send letters off to a server while you type in the search box.

In this article, we will take a look at the basics of AJAX and what role it plays in modern web development. We will cover what AJAX is, how it works, AJAX in action, and several ways in which the use of AJAX is beneficial to your website and user experience.

WHAT IS AJAX?

AJAX (Asynchronous JavaScript and XML) is a popular technique used in web development to create interactive and responsive web applications. It lets web pages update asynchronously by exchanging small amounts of data like text with the server in the background without needing to refresh and reload the whole page. This is a specific role of AJAX in web development. 

These asynchronous updates to web content (hence the “A” in AJAX) improve the user experience by making it more seamless and efficient. 

Features like Google Suggest are widespread in contemporary web browsing and that goes to show how important AJAX is in modern web development. 

JAVASCRIPT AND XML IN AJAX

So what does the “J” stand for in AJAX? As mentioned above, AJAX uses Javascript. 

JavaScript is a programming language used to make and manage dynamic content on websites after static web features like fonts and headers have been built with markup languages like HTML and CSS. 

JavaScript makes real-time updates of the website features like interactive buttons and GIFS without needing the user to refresh the page. This is why JavaScript is an important factor for AJAX’s asynchronous updates. 

What about the “X” in AJAX? XML, or Extensible Markup Language, is a coding language used to annotate web documents. It is like other markup languages like HTML and CSS in the way in which they are used to give web browsers instructions on how to understand, process, and display web pages. 

While HTML and CSS focus on the layout and appearance of the page, XML transfers data that is stored on the page to the browsers that view it. XML stores data in plain text format between tags. This makes it possible to be shared and understood across different software and hardware systems. On the web, data needs to be available and understandable across any and all platforms if possible. 

XML is used in practical ways, such as in creating RSS feeds, allowing users to access real-time updates from blogs and news sources.

HOW AJAX WORKS

Not having to reload a web page but still having minor updates occur in real time is a big deal in AJAX. Using a combination of JavaScript and XML makes this possible. 

When a user interacts with a web page, such as by clicking on a button or filling out a form, the JavaScript in the page sends an HTTP request to the server. The server then processes the request and sends back a response in the form of data, which can be in the form of XML, HTML, or JSON. The JavaScript in the web page receives the response and updates the page with the new data using DOM manipulation techniques. This allows web page updates to happen asynchronously and makes it feel more responsive and engaging to the user.

USES OF AJAX

Quick! Did you look up our company in your browser? A common example of how AJAX is used is in the creation of a search feature on a website. 

When a user enters a search query and clicks the search button, an AJAX request is sent to the server with the search query as the specific parameter. The server then scans a database for the query and returns a response with the search results. The JavaScript in the web page then updates the page with the search results, without updating the whole page. 

Did you know that the “Load More” button on a blog or social media website is also linked to AJAX?

When the button is clicked, an AJAX request is sent to the server asking for more posts to be loaded. The server responds with more posts and the JavaScript in the page updates the page with the new content, again without needing the whole page to be refreshed. Talk about an endless scroll. 

AJAX sure knows how to jack up the speed and interactiveness of web page content! 

BENEFITS OF AJAX

There are many benefits of using AJAX in web development:

1. IMPROVED USER EXPERIENCE

AJAX allows web pages to update asynchronously. This makes them come across as more responsive and interactive to the user, which can lead to a more seamless and enjoyable user experience.

2. INCREASED PERFORMANCE 

AJAX makes it possible for web pages to request only the data that is needed instead of loading the entire page every time there is an update. This can reduce the amount of data that needs to be transferred and improve the web page’s overall performance. 

3. REDUCED SERVER LOAD 

Because AJAX allows web pages to request only the data that is needed, it can reduce the load on the server. This can be particularly beneficial for websites with a large number of users, hence why we always recommend building software and web applications to be scalable. 

4. OFFLINE APPLICATIONS

AJAX can be used to create offline applications that don’t require a connection to the internet at all times by storing data locally and synchronizing with the server when the connection is re-established.

5. REAL-TIME UPDATES

AJAX lets real-time updates occur of the web page content seamlessly without having to refresh the page. This can be especially useful for applications that require real-time data, such as live sports scores or, if we turn back the clock to 2020, COVID-19 infection rates. Let’s not revisit that. 

IN A NUTSHELL

AJAX might not be an ancient warrior but it definitely is a modern-day web winner in improving user experience and site speed. AJAX combines JavaScript and XML to enable asynchronous updates to web content that make them ultimately more efficient and seamless.

Next time you type a query into a search bar, track the football game scores live on a website, or get caught up in an infinite scroll of posts and products on social media and e-commerce sites, that is AJAX in action.
