Nothing happens. Nothing at all. I see "rows" and "names" printed up,
but in my uplog.js, which contains the function startclock(..) which
has an alert in it, evidently never gets called. Worse yet, I get a
peculiar error in the Firefox Error Console when I click on the
link_to_remote link (the error is simply "Permission denied to call
method Location.toString). I am including all of the code below.
## Here is my partial that gets called:
<div id="namesdata" style="float: left; width: 200px;" >
names
<%= link_to_remote("StartClock",
:url =>{ :action => :clockstarter }) %>
</div>
<div id="rowsdata" style="float: left; ">
rows
</div>
## Here is clockstarter.rjs:
page.call "startClock" "../../../../www/test/ggriptest/getdata1.dat"
"./getdata2.php'"
## This is in my layout, which the partial is loaded into:
<%= javascript_include_tag "uplog" %>
## Here is /public/javascripts/uplog.js
