javascript = client-side
cf = server-side
the 2 do not meet unless you submit data to the server...
several options for you:
1) easy way: submit your form with the select's onchange
event and
process the form data to set the session var
2) if you are on CF8 you can use the new cf ajax features
like
cfajaxproxy to send data to a cfc
3) if you are not on CF8, you can employ rob gonda's ajaxCFC
to achieve
similar functionality
4) use a js framework like jQuery which supports asynchronous
requests
to send the selected value to a cfm/cfc
option 1) above will require page reload. other options can
do it
asynchronously without reloading the page, but you better
know your
javascript... and cf components...
