Regular Expressions (regex): /W with hyphen (javascript)

Question

I want to validate an user input. The user is allowed to write all characters, digits and "_" or "-".

I'm using

myString.search(/\W/) != -1

to validate. It works for everything I want, but not for the "-". How can I search for "no wordcharacter" but the hyphen "-" is allowed?

Answer 1

解决方案应该是myString.search(/[^\\w-]/) != -1

Answer 2

This should work:

myString.search(/[\W-]/) != -1

It's basically matching against a character class that includes any "no word character" and a hyphen.
