javascript to cfscript

[DJ_Jamba]

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

Couldn't you just get rid of the CFScript function and on your onchange do:
location.href="somepage.cfm?#UrlEncodedFormat(Encrypt(thingtodo,myKey))#

Or, I can't remember if this is the correct syntax, but set a variable equal to your function call
and append that to your url:

<CFSET EncString = doSomething()>
location.href="somepage.cfm?#EncString#

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>

Thanks guys - some good responses.
Just to clear up the typo at the top of my post : (CFMX or 5)

I'm gonna try both ideas in the morning so should reply early afternoon (GMT)

Art first glance:
james - i think the cf code gets processed first so I'm gonna place the js function at the point it's called and play around there.
cfpb - this looks possible. My problem is I was trying to eval the js var while inside a cf evaluate (urghhh) but your solution places the call on the option value (which incidentally is produced via cfloop). I cant believe i didn't think of this!

thanks for your help and i'll report back later..

cfbp - excellent! Your suggestion worked fine (even on the fly!)
Thanks for all your help
