Question

我无法使其中的任何一个工作。这是我的第一次尝试。过了一会儿，我确实在标签输出密码字段时看到了页面上的一些更改，但没有显示错误消息。这是相关文件。 这个想法是禁止免费的电子邮件域，如aol，yahoo，gmail等。如果你看到一个让它无法正常工作的错误，请帮助我。非常感谢你。

提交时出现错误但未实时出错 http://i.stack.imgur.com/x5qUR.png

Answer 1

<强> domain_validator.js.coffee

invalid_domains = [
"@myway.com",
"@mail.com" ] # two, for example, out of about 1,000

domains_joined = invalid_domains.join('|')
domains_pattern = new RegExp("^.+(#{domains_joined})$", "i")

clientSideValidations.validators.local["email_domain"] = (element, options) ->
  if (domains_pattern.test(element.val())) 
    options.message()

<强> LIB / email_domain_validator.rb

   class EmailDomainValidator < ActiveModel::EachValidator
      INVALID_DOMAINS = %w( 
         @myway.com
         @mail.com ) # two, for example

      def validate_each(object, attribute, value)
        if value =~  /^.+(#{INVALID_DOMAINS.join('|')})$/i
          object.errors.add(attribute, :email_domain, options)
        end
      end
    end

我也没有正确的错误消息。现在我做（email_domain）：

<强>配置/区域设置/ en.yml

en:
  errors:
    messages:
      email_format: "is not formatted properly"
      email_domain: "this email provider is not allowed" # tada!
