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.

The Ajaxa based elements stopped working (used to work) fine in the past. 1. Ajax Likes Function is not working anymore. There is a conliftc between the mod MemberLikes and SMF_Pro_Likes as they use both a function by the same name. This function needs tob e renamed.

    Hi there. I have an E-Commerce project and I need help combining 4 mysql tables into a function that outputs all the products (we actually already have a function made, but it's not fully working). I'm attaching an example of the API function's output which we are trying to re-create (and base this function on) - basically, we import the product data, so we can list the products from our local mysql database which is way faster than pulling the products from the API. The API example in my screenshot has lots more data than we actually need for the local version, so in the attached screenshot - just look at the "variations" part of it - that's what I need to add - and like I said I already have a function that works, but it's missing that part. I can g...

    I need this coded in java and it needs to work on netbeans program. I need a round robin algorithrn that will run on a load balancing machine (the load balancer will be working on a single machine while a number of client programs will be running on each of the nodes) Basically this is what it needs to do: standard round-robin algorithm working on a designated server machine (the load balancer). 2. Each node will register with the load balancer by sending a message. 3. The load balancer will record node details. 4. Jobs (sent as a message) require the load-balancer to assign the job to the next free node. The job information will detail the number of seconds that a job will take to run, rather than trying to include sorne form of code that is required to be executed. 5. The l...

    I use Flask backend and HTML frontend. I need HTML code that creates a Bootstrap table with dynamic columns depending on the number of columns in the input data received from server. Sometime the input data will have 2 columns, at other time it may have 5 columns. Accordingly the HTML table should show 2 or 5 columns. What I need is that the HTML table column (header and data) should change accordingly. There are a few columns that will always be fixed. My budget for this work is $10.
