Javascript to cfscript

Question

Hello Gurus
Wondering if this is possible?
(CFMX 5)
I have a cfscript function:
<cfscript>
function doSomething(thingToDo) {
return URLEncodedFormat(Encrypt(thingToDo,myKey));
</cfscript>
takes 'thingTodo', encrypts it with private key and then
makes friendly to use over URLs.
Now I want to pass in a JS variable instead of a raw string,
something like this:
<cfoutput>
<select name="selectObject"
onchange="javascript:location.href='somepage.cfm?#doSomething(this.value)#'">
<option value = "option1">Option 1
<option value = "option2">Option 2
</select>
</cfoutput>
so that thepage forwards to:
somepage.cfm?with_encrypted_js_variable_here
Is there a way to do this?
I have no hair left, so any pointers in the right direction
appreciated

Not sure if this is what your looking for but... how about
this?
Note: if you want to encrypt the values on the fly you'll
need to encode ( or encrypt ) through javaScript. I beieve the cold
fusion and javaScript are processed and run at different times.
<cfscript>
myKey = 'test';
function doSomething(thingToDo) {
return URLEncodedFormat(Encrypt(thingToDo,myKey));
</cfscript>
<script language="javascript">
function loadURL(str) { self.location.href = 'somepage.cfm?'
+ str; }
</script>
<cfoutput>
<select name="selectObject"
onchange="loadURL(this.value)">
<option value = "#doSomething('option1')#">Option 1
</option>
<option value = "#doSomething('option2')#">Option 2
</option>
</select>
</cfoutput>
