I've got a very simple need and I don't know what are the options available.
If I simplify, users see webpage like this server by a Java webapp server:
The selected color is green
And then I want the user to be able to select the yellow color and have the part of the page containing the relevant text change to:
The selected color is yellow
I'd like to use Ajax requests but I don't know which way to go:
What are my options and what would be the pros and cons of the various approach?
