How can I assign a variable with a JavaScript Function value return???

[colosoderada]

My question is:

if I have a JavaScript function

<script language=&quot;JavaScript&quot;>
int function Cambio(formulario){
int x, y = 10;
window.location=&quot;bo.01.cfm&quot;;
x = x * y;
return x;
}
</script>

How Can I to assign the result of the function to a variable????

<CFSET Result = ??????>

I have tried

<CFSET Result = #Cambio()#> (wrong)
<CFSET Result = '#Cambio()#'> (wrong)

Any idea, Thanks in advance.

It's the near classic problem of client-side and server-side processing. Javascript is being processed on the client, while CF is run on the server. So at the moment the Javascript will get executed, the only way you can store the result of your function in a CF variable, is to send the page back to the server so CF can store it and send it back to the browser. Not a good option I think ;-).
Consider writing a CF function that can do the trick for you. Another possibility is WDDX which can exchange data between CF and Javascript (it's XML-based), but things will get quite complicated then I'm afraid.
My suggestion is to write a CF function. Let me know if you can figure it out! Good luck
