HI,
i'm currently working on some web application and i would like to know
what
is the best way to do what i want.
basically like all application i have a menu and based on selected
item menu
i want to display a page (basically 50 % of this new page is DB
result/grid.
As usual i have 2 divs, one for the menu one for the content of DB to
display.
i would like to know if it's not better to use AJAX to load the
content of
the second div (DB result and other stuff) instead to every time load
a new
page which load menu and content of DB ?
what are your experiences on such thing ?
thx.

Alain:
The only difference the user experiences between having AJAX, or not, is
refreshing the page. If page refresh is not a problem, then don't
complicate your life. On the other hand, if page refresh is annoying, or
not wanted, then AJAX is you're only solution.
But as it has been said before, not all users have javascript turned on
and as such AJAX will not work -- after all, it javascript.
However, there are way to degrade gracefully from a AJAX site to a
normal site. Google
javascript graceful degradation" for references.
Please note, going the AJAX route does not make your coding simpler --
it's a different critter. But it does (with help from jQuery et al)
offer exciting new ways to present data.

this is a standard response for me recently; but have you looked in to
using flex 3 to build the clientside?
additionally ajax's main benefit (in my mind) is that it allows you to
pull down/update only the data you need, and not the whole page - often
this means you can skip out a large part of the templating and make the
php server side scripts so much lighter; very beneficial when polling.
Other than that, as everyone has mentioned - it's mainly a cosmetic thing.
