Share my laziness and solve a tricky problem.

A recent customer response, the system entered the phone number is the United States telephone, does not conform to the rules.

Need to improve compatibility, how to do, it is impossible to the world's mobile phone to adapt Ah!

Front code to do a classification choose it, divided into normal mobile phone number and special mobile phone number, let users choose?

But most users do not need to know the special mobile phone number, this is not scientific AH!!! So I thought of a compromise lazy way,

Click the input box pop-up tag tip Special mobile phone number please use # Start, so the front desk has not changed, and will not affect most customer experience,

The background only adds the beginning # character to judge to solve the problem.
