如何在 Rails 中格式化这个国际电话号码?

问题描述：

如果我有这样的国际电话号码:

If I have an international phone number such as this:

0541754301

我如何格式化它以产生这样的东西:

how can I format it to produce something like this:

0541-754-301

0541-754-301

答

但是，文档指出此方法将数字格式化为美国电话号码(例如 (555) 123-9876).

However, the docs point out that this method formats a number into a US phone number (e.g., (555) 123-9876).

相反，您可以使用这个补丁，它增加了提供数字分组的能力:

Instead you could use this patch which adds the ability to provide number groupings:

:groupings     - Specifies alternate groupings 
(must specify 3-element array; defaults to [3, 3, 4])

所以在你的情况下你会打电话:

So in your case you would call:

number_to_phone('0541754301', :groupings => [4, 3, 3], :delimiter => "-")

生产:

0541-754-301

0541-754-301
