ruby on rails - RoR onchange check condition before calling remote_function? -


I am using the remote_function call

onchange remote_function Iam

iam using the code written below

- Add name- ",: onchange => remote_function (: url => {: controller =>: name,: verb =>: Create_name})%>

Here I want to check that (value) == -1 then call remote_function

Why do you for example (escape (= value) == -1) {// do something} 

  for example you yoiur  r Emote_function  can check inside

or 

  if (escape (value) == -1) {// do something} else {// do not do anything or anything else}  
  def my_remote_function (var) s = "" if (var == "false") s =   
 "Warning ('java')" End of End " & lt; Option & gt; Br Use & lt; / Option & gt; ",: Onchange => my_remote_function (" true ")

But I do not think the code is capable of changing the color of each variable declared....
