It updates every second so, yes whenever the control value changes. Can I do this using node.js?
Odd question. Why Node.js? You mentioned in another topic that you are using servlets on the backend? Why would you change that to Node.js?
Updating on the server every second may be excessive? How may users will you have? Can your servers handle the total load?
Regardless, whenever you update the value of the text control, you can fire off an Ajax request to a servlet to save the value.
Check out jQuery and its Forms Plugin to make this almost trivial.
