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

    fix small jquery script 6 días left
    VERIFICADO

    I am looking for someone to help fix a small jquery script. The script is written in jQuery, so you need to be familiar with that language. I need the script tested and also modified, if necessary, to improve its functionality. Once you’re done, I need the script uploaded onto the server. Even if the script works as intended, I would like a report on what you changed, and the results of any tests that you conducted. The scope of this project may change depending on the results of the work. Please let me know your experience related to this project. Thank you! Here the error: Access to XMLHttpRequest at '$SERVER/' from origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

    I have a web page (attached) that opens modal popups for audios, videos, and multiple levels of text. Clicking ESCAPE calls a function that closes one popup (just one level). If there are more than two popups open, it closes the top one. REQUEST: I want the browser back button to do the same thing as clicking "Escape". In other words, I want the browser back button to have the effect of closing one popup. HOWEVER: If there are no popups open, then clicking the back button should take user away from the page. Therefore, using a method won't work here. Such a solution would lose all modal/popup levels anyway. I believe the solution needs some combination of pushState, popState, replaceState, and/or perhaps something I'm not aware of. *This is a request for JavaScript...
