RE: Javascript enabled
I'd suggest going with Josh's example. It's simple and unobtrusive.

I've an (old, but still applicable) article here that does this:
http://www.depressedpress.com/Content/Development/ColdFusion/Articles/GetRes
/Index.cfm
Basically you set a noJS variable as being zero. On the page one of the
images (in the examples it's a single pixel, transparent GIF) is written by
JavaScript (and sets several values to be sent). The image called is
actually a CF page which updates the session values and returns the GIF
image.
Your user can log on normally but be redirected to a you need... page
immediately following. If Script isdisabled the check will still fail if
images are also disabled. So your you need... page would have to reflect
that information as well.
There are a lot of improvements I could see to this (the article is seven
years old) but as it is it'll do the job. Namely you could use an existing
page graphic and also output a noscript section to ensure that it get's
called even if script is disabled.

RE: Javascript enabled
You could set up your login page like...
div id=noJSMessage style=display:block;You need javascript/div
div id=theForm style=display:none;form name=login...
etc...,/form/div
Then run some js that changes the display for each.
script
document.getElementById('theJSMessage').style.display='none';
document.getElementById('theForm').style.display='block';
/script
If the user doesn't have JS, the login page is a message that says You need
JS. If they DO have JS, the login page hides the no JS message and displays
the form but either way... application.cfc includes the login.cfm as usual.

Re: Javascript enabled
we would appreciate some help on how you guys to do your checks when you have the application.cfc handling the logging in of users. We would like the application.cfc onrequeststart method to check this all the time so that if the user turns of javascript while using the software it will inform them straight away that they cannot continue until they turn it back on The best you can do is set up an ajax call that sets a session variable like session.jsenabled = true. Default it to false. If the ajax call works (javascript is enabled) set the session variable to true. From the second request on, the server will be aware via the session.jsenabled variable if the user has js enabled or not. But, this does not quite get you where you need to be because a) it only helps from the second request on, and b) it does not check if the user has turned off JS during the session. However, it may work well enough for your needs -- it's extremely rare that someone turns js on or off in the middle of a session, or ever for that matter. Generally, it's either on or off. -- Josh - Original Message - From: Richard White [EMAIL PROTECTED] To: CF-Talk cf-talk@houseoffusion.com Sent: Saturday, November 10, 2007 9:20 AM Subject: Javascript enabled Hi, before we set up the application.cfc to handle the login in of users we had an index page that was told the user that they didn't have javascript enabled. at the top p fhte form we had code in javascript that redirected them to the login page. therefore if javascript was enabled it would direct them to the login, and if it wasnt it displayed the error to them saying that they didnt have javascript enabled however, we have now setup the application.cfc to handle the login of the client. it works in the same way as the coldfusion livedocs explains ... if a user is not logged it it includes the login.cfm page. so now we need the application.cfc to check whether a client has javascript enabled but we cannot figure out how to do this. as of course the application.cfc is on the server but it needs to go to the client to find out if javascript is enabled and then come back to the server. we would appreciate some help on how you guys to do your checks when you have the application.cfc handling the logging in of users.

One of my co-workers showed us one of his login forms, and we were like
duh...
Just wrap the form in a cfsavecontent tag and use javascript to display the
form.
cfoutput
!--- Save form as cf variable so we can display with js ---
cfsavecontent variable=sFormContent
cfform action= method=post scriptsrc=
cfinput type=text name=fieldName
/cfform
/cfsavecontent
!--- Here we display the form with js and also a noscript message ---
div style=margin:10px 0px 0px 25px;
script type=text/javascript language=javascript!--
document.write('#JSStringFormat(sFormContent)#');
//--
/script
noscript
div style=padding:8px; background-color:##CC;color:red;
pYou must enable javascript in order to submit use the form on

Enable javascript and refresh this page to continue./p

Re: Javascript enabled
thanks for all your replies, i was just wondering josh.. i was interested
in what you said about the ajax call, is this
something simple to do... if so could you provide a short example of the
ajax call?
Sure, I use jQuery and it looks like this - keep in mind I have already
cfparam'd session.jsenabled = false, and included the jQuery source file
before this. I think the other people who posted might have better
solutions for your particular implementation, but this is a good technique
to know about nonetheless.
cfif not session.jsenabled
cfoutput
script type=text/javascript
$(document).ready(function() {
$.get('shop/includes/setjsenabled.cfm'); // this is the ajax call
});
/cfoutput
/script
/cfif
Then setjsenabled.cfm is one line:
cfset session.jsenabled = true
onSessionEnd then logs the value of session.jsenabled into a db table when
the session ends. This way we can easily see what percentage of our
visitors have js enabled, because session.jsenabled will never be set to
true if the user does not have JS enabled.

Re: JavaScript Enabled Stats
This idea rules -thanks!I had never thought of this, but played with a bit and could find myself using it a decent amount. You could use JS to load an image that's really a CFM page -- new Image().src = "" . You would embed code to add the record (set to notEnabled) in your page, and add code to the stats.cfm file that would toggle it to enabled.
