How to access javascript variable with CFC?

Experts,
I would like to understand the best approach to accessing a javascript function from Coldfusion. Can someone please, in the simplest terms possible, please give an example of a way to do the following. Coldfusion 8.

<script>
   var hasThePlugin = isInstalled();
</script>

<cfset CFhasThePlugin = hasThePlugin>

Open in new window

I have no access to the "isInstalled" js function.

I feel this is a simple implementation of the cfajaxproxy tag but I'm just not getting it.

Thanks!

<script>
   var hasThePlugin = isInstalled();
</script>

<cfset CFhasThePlugin = hasThePlugin>

Open in new window

Yes, and the more research I've done the more I understand, thanks for the reply.

I have successfully managed to use cfajaxproxy to update the value of a form element based on the reply to that function call, and that will work for me.

Apologies if this is off topic, but is it possible for my bind in the proxy to be fired when the page loads, as opposed to relying on a users action?

Something like:

<cfajaxproxy bind="javascript:isInstalled({vLoginName@PAGELOAD})" onsuccess="callBackHandler">
