What ever it is, its impossible to write this functionality without making any call to the server. Most likely it will be a J2EE server or a .NET server.

After some validations in javascript, it has to make a call to the server:

1. Use ajax call, making use of ajax API that most of the browsers are providing now. Server will respond with simple text or XML

2. Use ajax frameworks like DWR, Dojo to ease the process of communication, server will respond with JSON or XML mostly.

3. Make a RESTful call to the server (but directly invoking a SOAP call is not yet possible from browser directly).

 

The browser will be in suspended mode awaiting response from the server. Once the response is received, the browser unblocks and  then either:

1. Use simple Javascript to parse and update DOM element (in this case your text box) using DHTML API like getelementById()

2. Use jQuery unobtrusive DOM access capability to update the item. (seriously a million ways of getting an element will be possible if you use jquery).

 

If you want any more clarity, can explain you in detail.

No Alexander. Its now a days more OO-Javascript that is more in demand than the traditional server-side Design Patterns like MVC.

latest OO-Javascript paradigm provides MVC on client side instead of on the server side so that client maintains and manages all the state of the conversation instead of having server to hold all those session data for hours.

 

However this is very latest (started since some 5 years only) and they argue that there is no point in NOT utilizing the computing power of the user machines however advanced are the server nodes.

check if its old javascript they may be using xmlhttprequest(ajax object)......
