AJAX Page - Asynchronous Callback

Make a callback with data asynchronously

The next example makes a callback to the server with two numbers (49583 and 83924).
The server-side method waits 5 seconds and then returns the sum of the numbers.

The syntax is:

        ob_post.AddParam("number1", 49583);
        ob_post.AddParam("number2", 83924);
        ob_post.post(null, "myServerMethod", myFunction);
You can still work on the page while waiting for a response from the server. Click to test:

In the next div, a dot is added every 0.5 seconds.
You will see this doesn't stops after you make the callback.
