regex - Regular expression which accepts 'whitespace' character as well

Question

This is my regular expression. But it does not accept white space. How to modify it so that it will accept white space in the middle or end but should not accept only white spaces.

    /^[a-zA-Z]+[a-zA-Z0-9._-]+$/'

Answer 1

以下はあなたのために働くはずです。最初の文字の後に空白を許可します。 ^[a-zA-Z]+[a-zA-Z0-9\s._-]+$
