Need to convert PHP Regex into JavaScript regex

Question

I need to convert this PHP flavoured Regex:

(?<=\A|\;#)(.*?)(?=\;#|\z)

Into Javascript flavoured Regex.

I keep on getting unidentified token error while using the existing PHP version in my code.

Appreciate the help.

Javascript does not support lookbehinds, I think you may be better off explaining what you are trying to match with some example content — Rob M.

JavaScript doesn't support lookbehinds, nor are \A and \z anchors.

You don't really even need a lookarounds in that regex. You could just use a non-capturing group, and then access the first capture group. Use ^ instead of \A, and $ instead of \z. You also don't need to escape the ;.

(?:^|;#)(.*?)(?:;#|$)

And then use the value in the first capture group.
