用于验证名称的正则表达式

Question

I am trying to validate an address input field on my form and it must be entered in the following format "City, Province, Country"

I am using the following regular expression to do this

^[^,]+,\s\w[^,]+,\s\w[^,]+$

When entering "New York, New York, United States" this would be valid. However, when I enter "N, N, United States" it does not work. It seems one letter words will not work. I need to allow users to only enter a single letter as well.

Not sure if the regular expression I have written is complicated and can be simplified

Answer 1

Make sure to check for dashes:

((\\w)|(-)|(\\s))+,\\s*((\\w)|(-)|(\\s))+,\\s*((\\w)|(-)|(\\s))+$
