关于Ruby on Rails视图编写的一些建议

 module ClientSideValidations::Middleware
   class Email < Base
   def response
    if request.params[:email] =~ /^([^@\s]+)@(("htmlcode">

  
  # app/assets/javascripts/application.js.coffee
  #= require rails.validations.custom




        添加你的用户端 validator：


  #public/javascripts/rails.validations.custom.js.coffee
  clientSideValidations.validators.remote['email'] = (element, options) ->
   if $.ajax({
   url: '/validators/email.json',
   data: { email: element.val() },
   async: false
   }).status == 404
   return options.message || 'invalid e-mail format'
