本文展示了一个使用Ruby on Rails进行远程验证的例子。具体包括如何通过ERB模板渲染部分视图，以及利用remote_function方法实现表单字段的实时验证。

.erb

<div id="customer_out">
    <%= render :partial => "customer", object => @customer_out%>
</div>

.erb

  
<%= f.text_field :username, :onchange => remote_function(:update => "customer_out",
                                                                                                          :with => "'username='+$(this).value + '&come_from='+$('customer_out[come_from]').value",
                                                                                                          :url =>{:action => 'check_customer'} ) %>

.rb

  def check_customer
    @customer_out = CustomerOut.find(:first, :conditions => ["username = ? and come_from = ?", params[:username], params[:come_from]])
    if @customer_out
      @customer_out = CustomerOut.new
      @consignee = @customer_out.customer.consignees.find(:first)
     end 
    render :partial => 'customer'
  end
