Rails - Jun 2006 - JS variable -> ruby?

I have a little javascipt script to determine a users GMT timezone 
offset... is it possible to use that variable in ruby code, in the view?


js script:

<script type="text/javascript">
	Now = new Date();
	tzOff = Now.getTimezoneOffset();
        tzOff = tzOff/60;
</script>

Thanks!

Not directly, in as much as the ruby is executed on the server when the 
page is served, and the JS is executed on the client.  You can sort of 
merge the two by doing RJS, which is ruby code that generates 
javascript.  ie the Ruby is ultimately executed on the client instead of 
the server.

A,

Javascript is only executed after the render is finished.  So the only 
way is to post an Ajax request with the content you want back to the 
server, like on page load or something.
