问题描述

我将电话号码存储为"1234567890".

I am storing phone number in database as "1234567890".

如何使用number_to_phone以(123)456-7890"的形式很好地显示数字?

How do can you use number_to_phone to display the number nicely in a form as "[phone]"?

我尝试了以下操作，但只显示了数字.

I tried the following but it showed just the numbers.

谢谢.

推荐答案

您可以在应用程序帮助程序中创建一个像这样的简单帮助程序

you can create a simple helper like this in your application helper

  def format_phone(phone, mobile=false)
    return phone if format.blank?
    groupings = format.scan(/d+/).map { |g| g.length }
    groupings = [3, 3, 4] unless groupings.length == 3
    ActionController::Base.helpers.number_to_phone(
      phone,
      :area_code => format.index('(') ? true : false,
      :groupings => groupings,
      :delimiter => format.reverse.match(/[^d]/).to_s
    )
  end

然后您认为

<%= format_phone(phone_number)%>
