Hi,
Anybody know why :onchange works here...
<%= select_tag "Minisections",
options_from_collection_for_select(@minisections, :id, :title, :selected
=> @minisection.id), {:onChange => "{alert(''Minisection has
been changed
to x !'')}"} %>
but NOT here (to call a function)...
<script type="text/javascript">
function xyz() {
"{alert(''Minisection has been changed to x !'')}"}
</script>
<%= select_tag "Minisections",
options_from_collection_for_select(@minisections, :id, :title, :selected
=> @minisection.id),
{:onChange => "xyz()"} %>
The function is at the top of the .html.erb page. I have used a similar
format with :onclick and it works fine.
Thanks,
DC

Then go to http://validator.w3.org and use the Direct Input tab and paste. Validate your page. If it passes there, then enable Firebug in your copy of Firefox, open up the console section, and visit your page. You either have an HTML/DOM error or a JavaScript error. Once you figure out which one you''re dealing with in this case, you can proceed to a fix.

Thanks 7stud, I am trying to learn Rails, HTML, Javascript, and Ajax but am learning on my own. No programming background. I spent a couple of days trying to figure this out before asking the question, and did Google it . Been working on this project for over a year (maybe longer) and have only asked for help a few times. Up till your reply, everyone has been very helpful.
