[jQuery] Re: Best way to determine if a user has Javascript enabled?

[Ariel Jakobovits]

how about this:

WHEN THE USER FIRST LOGS IN:
--------------------------------
<cfset Session.isJSEnabled = 'no'> // assume false for now


JAVASCRIPT ON PAGE:
-----------------------------------

var myUrl = 'http://myhost.com/someCFMfile.cfm'; // some URL pointing to the 
page as defined below

var ajaxSettings = {
            type: 'GET',
            url: myUrl ,
            dataType: "html",
           data: {isJSenabled: 'yes'}
        };
        
jQuery(function () {
    jQuery.ajax(ajaxSettings);
});



FILE ON SERVER (Cold Fusion example):

-----------------------------------
<cfset Session.isJSEnabled = URL.isJSEnabled> // now it is YES and you can use 
that later in generating pages


Basically, you fire off a message to the server saying that yes JS is enabled. 
Update the session, and use that from then on in your code.
