REGEX works in chrome but breaks in safari

Question

The following javascript regular expression causes SyntaxError in safari: Invalid regular expression: invalid group specifier name"

/^(?!\s)[A-Za-z0-9\'\.\-\,\s]*(?<!\s)$/.test('ABCD@#');

Can someone help me rewrite the regex that will work in safari?

I found out that safari doesn't support lookbehind, but still can't rewrite the whole regex, which would be useful for safari.

Answer 1

Modify your schema to avoid negative reviews. Since you seem to want a non-whitespace character as the last character, just use a character class.

/^(?!\s)[A-Za-z0-9'.,\s-]*[A-Za-z0-9'.,-]$/.test('ABCD@#')

Side note: Your current pattern looks wrong for what you are trying to match.
