Hello.
I tried to invoke javascript in the controller, but I couldn't.
What I want to do is,
I'd like to verify passed parameters in the controller,
if parameters are not verified I'd like to invoke alert with error
message and back to othere function.
code will be like below
if verify? params[:value]
#call alert('value is not correct') <- how can I implement this
function?
redirect_to :action => 'index'
return
end
how can I implement that function?
can I insert javascript function before and after of redirect_to
action?
and my second question is
<script>
var foo = new myclass {
function open() {
}
}
</script>
<%= link_to_remote 'click me', :update=>'blah'. :url=>
{:action=>'something'}, :before=>'foo.open();' %>
When I clicked, javascript error occured, "foo is not defined"
if javascript is like "alert('blah');" it works.
Maybe local and global is the difference while I'm not sure.
anyway, how can I invoke javascript object that is not gloal object?
