What is the preferred way to do AJAX.
If it was for a search page written in PHP using Jquery for the AJAX
How would you handle the response
a) Have the response contain all the relevant html/styling
or
b) Send pure JSON and have a javascript function build the html/styling around the javascript variables.
I can see advantages to both. 'a' is obviously easier whilst 'b' is more efficient (although gzip would probably make the difference negligible).
