Rails客户端验证条件

Question

嗯，有两个div，正如您从代码中看到的那样，一旦页面加载和select_tag值发生变化，我就会动态显示它们。从模型中可以看出，两个div的帮助程序都是按条件在服务器端验证的。我想在客户端做同样的事情。因此尝试仅针对状态强制验证，尝试使用f.object，启用和禁用验证。没运气。 一旦表单被加载，服务器端的条件被加载，所以第一个div通过加载＆＃34;个人＆＃34;但是当我加载另一个div（由js）;因为条件是为了个人而加载的＃34;商业类型，条件为＆＃34;公司＆＃34;没有工作，客户端验证不会被解雇。部分使它变得复杂，我无法重新加载页面，因为有没有缓存选择的图片和实时地图数据。

我是否有任何关于客户端验证的信息，您可能会建议我对此进行排序？

模型

 validates :tax_number, length: { is: 10}, presence: true, uniqueness: true,  :if => :company? 
  validates :tax_office, presence: true, :if => :company? 
  validates :tax_business_name, presence: true, :if => :company? 
  validates :tax_pin, length: { is: 11 }, presence: true, uniqueness: true, :if => :personal? 
  validates :tax_fullname, presence: true, :if => :personal? 

  def personal?
    if business_type == 1 || business_type == 0
        return true
    else 
        return false
    end
  end

  def company? 
    if business_type == 2 || business_type == 3
        return true
    else 
        return false
    end
  end
