Ajax, or Asynchronous JavaScript and XML, is a powerful development technology used to create faster and more dynamic web applications. This means that an AJAX developer or engineer helps businesses create the most responsive web experiences for users. Through its interaction with the server, AJAX can improve the performance of web applications, aiding in loading time and overall responsiveness. With Ajax, web developers can create complex user interfaces from multiple data sources that use far fewer resources than traditional web-based applications. Ajax-enabled applications also tend to be more accessible, being compatible with a wide range of browser technologies such as HTML, CSS and JavaScript.

An AJAX Developer's expertise helps to build look attractive but simple user interfaces. They take complex application architectures and make them simpler for users by defining how to collect data from different sources and how to display it in a unified interface. They also make sure that their applications are device-independent and compatible with their intended devices.

Here’s some projects that our expert AJAX Developers made real:

  • Creating login pages quickly and securely
  • Building hotel websites with powerful API integrations
  • Designing efficient user interfaces to enable sorting of posts
  • Facilitating likert scale forms using modern frameworks
  • Developing single pages using databases, PHP, and libraries like Handsontable

    Shopify Cart Bug Fix -- 2
    6 days left
    Verified

    I’m running the Prestige theme on Shopify and the cart has started misbehaving on mobile—both iOS and Android. Whenever a shopper adds a product, the cart grabs the previous item instead, so the cart is always one step behind. Swiping through product images or switching variations triggers a “SyntaxError: The string did not match the expected pattern,” blocking the add-to-cart action entirely. Removing items or updating quantities fails as well. Key pain points you’ll tackle: • Adding products, removing items, and changing variations must work reliably on mobile. • The cart should display the correct, current product every time. • No more SyntaxError on variant change. I haven’t modified the theme or added new apps recently, so the...

    I am currently using Geo my WP, but I want to switch to WP Go Maps with the Pro Add on, and I’d like to configure the map with the following behavior: My website introduces many attractions around the world. For example, let’s say I currently have four attractions posted: Attraction A, B, C, and D, and they are all located close to one another. • When I’m viewing the page for Attraction A, the map should display: o Attraction A using Icon 1 o The other three attractions (B, C, and D) using Icon 2 • When I’m viewing the page for Attraction B, the map should display: o Attraction B using Icon 1 o A, C, and D using Icon 2 This is similar to what TripAdvisor does — for example: The main attraction shows with a unique icon, while nearby attractions appea...

    Fix PHP Admin Panel Bugs
    4 days left
    Verified

    Our PHP-based admin panel has suddenly become unreliable inside the User Management area. I can no longer add, edit, or delete users, role and permission assignments fail to save, and the user lists sometimes come up blank. I haven’t caught any clear error messages yet, so you’ll need to trace the problem directly in the code or logs. What I need from you is a quick, surgical repair: locate the root cause, patch the broken functions, and confirm that all three actions—create/update/delete users, assign roles correctly, and display user data—work again without introducing new issues elsewhere. You will have SSH/FTP access to the server, the Git repo, and a staging database to test against. Once everything is stable on staging, I’ll roll it to production. Ple...
