Calling local js function within form_remote_tag

Rails
1

Hi ,

I am trying to pass an additional parameter using the form_remote_tag
like this

<%= form_remote_tag :update => ‘’, :url => { :action =>
‘send_msg’, :to => nowActive()}, :after => “clearinput()” %>
<%= text_field_tag :newmessage, nil, {:size => “210”, :maxlength =>
“1000”,:autocomplete => “off”} %>
<%= end_form_tag %>

On running the page I get the template compile error, saying that
nowActive is not a method in my controller class.

I guess it’s checking for the method on the server side, where I want
to pass the parameter value derived from a local js function.

Please help.

Thanks,
