Try creating an IFRAME and have your page which wants the client vars call
the iframe like this:
<cfoutput>
<script language="javascript">
function getClientVars(clienvar){
document.myiframe.location.href='www.mywebsite.com/getclientvars.cf
document.myiframe.location.href='www.mywebsite.com/getclientvars.cfm?request
edvar='+clientvar+'&cfid=#cfid#&cftoken=#cftoken#'
}
</script>
</cfoutput>
Then in the getclientvars.cfm template just set something like this:
<cfparam name="requestedvar" default="empty">
<cfoutput>
<cfif isdefined("client.#requestedvar#")>
<cfset x=evaluate("client.requestedvar")>
<cfelse>
<cfset x="undefined">
</cfif>
</cfoutput>
<html>
<head>
</head>
<!--- call the parent frame (or name it absolutely) and
tell it we have finished loading and the variable is set.
Note: you could also dump the var in a hidden form
field... --->
<body onload="finishedloading('#requestedvar#','#x#');">
</body>
</html>
Then put this in the calling template:
function finishedloading(VarName,VarValue){
alert('The request client var '+Varname+' is '+VarValue+'.');
// eval('var '+varName+' '+\''+Varvalue+\'') }
You might have to play with it a bit, and I wrote this in my email so, it
may have some syntax mistakes in it. You might also consider passing the
name of a function to call on the way back as part of the initial argument.
Then you can do something a little more useful with the result and unique
for each type of call made.
