Re: FLASH: Detecting if java enabled for CFSET flashmoviename.swf

[Erik Mattheis]

Isn't "java" a reserved word in JavaScript? ... changing it to useJava here ...


A solution would be to set a cookie with JavaScript that holds the 

value of navigator.javaEnabled() ... make sure to include path=/ or 

ColdFusion won't find the cookie. At the top of your template have 

something like:


<cfparam name="useJava" default=0>

<cfif useJava>

	<cfset theSwf="javaVersion.swf">

<cfelse>

	<cfset theSwf="non_javaVersion.swf">

</cfif>


In your javascript, have something like this:


<cfif NOT useJava>

function checkJavaCookie(){

	if (document.cookie.indexOf('useJava=1') >=0 || 

document.cookie.indexOf('useJava=true') >=0)

		{ location.reload(true); }

	}

onload=checkJavaCookie;

</cfif>


A java enabled visitor always sees the non-Java version load the 

first time they connect to one of your pages like this, but that's 

the only time. If your non-Java version can take a while to load, you 

could check the value of the useJava cookie every half second or so.


I'm doing this type of thing to serve Flash 4 to those with it at 

http://gozz.com/ and plain html to those without it ... can send you 

the full code off list if you want.
