Novice RoR programmer here, I''ve run into a bit of a stumbling block,
concerning Time.now seemingly not updating in between JS function
calls.
My code is as follows:
function test()
{
document.getElementById("chatbox").value += "<%= Time.now
%>" + "\n";
}
...
<textarea id="chatbox" rows="10" cols="80"
class="chatbox"
readonly="true" onclick="test();">
</textarea>
Basically, clicking the textarea "chatbox" will add a line with the
current time, and unfortunately, every click on the textarea results
in the identical line being written, which is the time that the page
was loaded.
Is there any way I could get Time.now to update with every click?
Thanks in advance!
Nick.

If you need some ruby code evaluated you need to make a request to the server Fred> > Is there any way I could get Time.now to update with every click? > > Thanks in advance! > > Nick.
Ahh I see, thank you very much for your help Frederick!

In any case, I would advise against using ERb in JavaScript...> > FredBest, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/.
