CF can only read variables that are sent back via an HTTP request. So, to
pass a variable from JavaScript to CF, you'll have to write JavaScript code
to request a cfm file. Here's an example, using the ternary conditional
operator, which is similar to CF's IIF function, instead of an if statement:
<script language="JavaScript">
var mylanguage = (navigator.appName == 'Netscape' ? navigator.language :
navigator.browserLanguage);
parent.otherframe.location.href = 'somefile.cfm?mylanguage=' + mylanguage;
</script>
Then, of course, you'd have to do something with URL.mylanguage in
somefile.cfm. In addition to appending variables as URL parameters, you can
also use JavaScript to programmatically submit forms.
