Change HTML code without refreshing the page

Question

Is there any possibility how to change HTML (.jsp) page without refreshing it?

Usecase is that user writes something to textarea then hits

Answer 1

You should use the javascript function document.getElementById (DIV THAT YOU WOULD LIKE TO PLACE IN).innerHTML = YOUR_TEXT;.

If you need a response from the server without reloading the page (you will still have to load, but the client will not notice), try using AJAX.
