Hi I am very new to this two
If the browser disable the javascript, what happen to Ajax? can i slove
the problem by using server side script? any suggestion for this?
i currently do some dirty projects with perl/cgi, and I would like to
add more client side features which relate to ajax, and do some
validation on the client side with javascript. but it is possible that
the javascript may be disable with some browsers. what can i do if the
client's broweer disable the javascript.
thank you

You're SOL if JavaScript is disabled.

Fall back to conventional server side processing.

Ajax is a buzzword that basically means "Using JavaScript to make
requests to the server and process the response".
If JavaScript is disabled you can't use it to make such requests.

That depends what the problem is. Ajax is just a technology. It might
be used in a solution to a problem, but it isn't a solution in and of
itself.

Never ever depend on the client to ensure data integrity / sanity. You
are effectively asking the user to police themselves. By all means use
it as a convienience to the user, but check the data again when it gets
to the server.
but it is possible that the javascript may be disable with some browsers.

If its fluff, just forget about it, the user will get a slightly less
nice experience (well, depending on the fluff, sometimes things work
better without the JS).
If it does something useful, have a server side fallback.
I usually code javascript which embed in Html form before I call the
server side script, I do all the validation in client side before it
goes to Server side. But it isn't possible for me to know if the client
already disable javascript. What method should I use to check for
browser and javascript, so incase I will not send the Html form with
Javascript that can not run in the client? The answer that I already
think off is, using server side script to check and if the client isn't
disable the javascript, then print the html form with javascript embed,
else I should use all the server side script.
Pondering the eternal question of "Hobnobs or Rich Tea?", jpaul finally
proclaimed: I do all the validation in client side before it goes to Server side.
But it isn't possible for me to know if the client already disable
javascript.
I'd just have the server-side scripting re-validate the user input
anyway. That way people with Javascript support will have their input
validated quickly without them having to wait for the server to respond,
but as a fall back users without scripting enabled will still have their
input validated, but in a slightly longer process.
I wouldn't waste time trying to figure out whether the client supports
scripting or not, and sending different pages. That's just counter
productive.

Simple answer: AJAX stands for "Asynchrono us Javascript and XML".
Therefore, without Javascript there can be no AJAX.

As a task of getting a project complete it can be counter productive, but
as an end result the javascript validation can make the experience more
polished and professional if done right.
So? Write one page that degrades gracefully if JavaScript isn't supported.

I have a asp.net form where if the user checks a check box I need to disable
some of the fields. I don't need to make a trip to the server for anything
at this point so is this is a case of using javascript to disable the fields
or should I be using Ajax do that? As probably can be seen from my post I
have never used Ajax yet.

I have a simple page - 2 dropdowns, 2 textboxes. 1 set of dropdown/textbox
is in the updatepanel. 1 set of dropdown/textbox is not. When I select a
dropdown the textbox is updated with teh value.
Why is it that the updatepanel one still seems to "flicker" on postback? I
would think that because I have it in an updatepanel taht it wouldn't.
(Yes, I have scriptmanager before it.)
