Using JavaScript, I wanna check if a giving string contains only letters or digits and not a special characters:

I find this code which checks if a string contains only letters:

    boolean onlyLetters(String str) {

      return str.match(^[a-zA-Z]+$);

    }

but my string can contain digits too. can you help me?

thanks in advance :)

Add 0-9 also to your regex

 boolean onlyLetters(String str) {

   return str.match(^[A-Za-z0-9]+$);

 }
