Hi,

Is it possible to call a Rails controller from a javascript function?

This is part of my code: <%= start_form_tag({:action=> "index"}, {:onsubmit => "clickResult(); return false;", :autocomplete => 'off'}%>

The clickResult() function: function clickResult() {   window.location = "http://myblog.com/post/&quot; + document.getElementById("Highlight").firstChild.id; }

I want to call this function from javascript because now I have to hard-code the url: def permalink     @post = Post.find(params[:id]) end

Any ideas? MJ

This might work, I haven't tested it at all, but it seems like it should do the trick... The main addition is the 'remote_function' action, which performs a Ajax request to the given parameters

<%= start_form_tag({:action=> "index"},                    {:onsubmit => update_page{|page|                                    page.call('clickResult')                                    remote_function(:url => {:controller => 'some_controller),                                                    :action => 'permalink',                                                    :id => post.id})},                     :autocomplete => 'off'})%>

The clickResult() function: function clickResult() {   window.location = "http://myblog.com/post/&quot; + document.getElementById("Highlight").firstChild.id; }

Sorry for the syntax error! here's the fix

<%= start_form_tag({:action=> "index"},                    {:onsubmit => update_page{|page|                                    page.call('clickResult')                                    remote_function(:url => {:controller => 'some_controller',                                                             :action => 'permalink',                                                             :id => post.id})},                     :autocomplete => 'off'})%>
