AJAX is the art of exchanging data with a server, and updating parts of a web page without reloading the whole page. It is not a new programming language, but a new way to use existing standards. AJAX is used to make sites interactive. It can be used to create Facebook apps, picture-uploading interfaces, and much more. If you need to add functionality to an existing or new website and don\'t have the programming knowledge, our expert developers can create whatever you need.

If you are AJAX developer, Freelancer.com offers you a lot of clients who need your help with their AJAX projects which might vary from creating Facebook apps, picture uploading interfaces, and much more.

If you believe you can do that, then start bidding on AJAX projects and get paid with an average of $200 per project depending on the size and nature of your work.

    We need a two page dashboard web-app to present data that is sampled with a mobile GPS altimeter/tracker for data analysis. The mobile device collects GPS, pressure and acceleration data and stores it in its internal SDcard. To connect to the dashboard and cloud storage, the device connects via WiFi with the server, reads the internal SD Card files and transfers the data to the dashboard for further analysis, display and storage. More detailed description attached. The web-app should start as a responsive desktop app with the option of generating native mobile apps later.

    I want to create a simple (for starters) online game/app reminiscent of the Horse Racing Board Game we used to play at home. But instead of horses that will progress based on the outcome of a dice, we will have stocks (shares), progressing based on their daily performance at the stock market! The game will be played with only two rival stocks ('horses'), let us say during the weekend. People will choose two rival stocks (say IBM and Apple) and 'bet' who will the winner at the end of the week. For example someone can bet 'IBM will be the winner' which means that IBM will be ahead of Apple on Fridays close, even by 0.01%. The game will also feature a database of players' bets. There are more details of course, which will be discussed in person with inte...

    jQuery Ajax small fix 3 días left
    VERIFICADO

    I have a function that makes an ajax call every 4 seconds but on some cases this is a overkill for the server because the 1st ajax request still hasn't returned while the script sends a 2nd ajax request. This keeps piling up and it slows down the site until it starts having errors and issues. We have to run a check to not send a next ajax request unless the previous one has returned successfully. This should be a small and quick fix for anyone who knows what he is doing.

    The App will be used for Paint Manufacturing Industry and caters the benefit transfer to painters buying Paint Boxes from dealers across India. Currently, the process we follow for transferring benefit to Painters is by giving vouchers to dealers and ask them to distribute to painters to attract them to consider our brand paint , but the actual benefit is not transferred to painters and dealers are not passing the benefit due to which our sales are not increasing. We have decided to increase sale , we would need to find a way to benefit directly to painters. And for the same, we plan to have QR code in all paint boxes which will be inside the box. So once the painters purchases it, they would get the QR code inside the box, and We would ask them to download our App that we are looking...

    Hi there. I have an old website (it's currently on PHP 5.6) that was built on the Smarty Template style with an MVC folder structure. I'm going to update it to PHP7.0 or PHP7.3 soon. I have a comments feature with built in replies that used to work perfectly, but I think someone accidentally deleted the AJAX part. I need help fixing it, so it loads the replies instantly and so the image upload works again. I'm attaching some of the files that I think may have parts that affect the comments/replies and screenshots. Note: we built this as a Featured Questions content object which is based on "projects" in my site (projects are basically like a universal post/blog object that can be used for anything and have a project_type).
