试试这个：

^(?:10|[1-9])00(?:,\s*(?:10|[1-9])00)*$

The regular expression:

(?-imsx:^(?:10|[1-9])00(?:,\s*(?:10|[1-9])00)*$)

matches as follows:

(?-imsx:                 group, but do not capture (case-sensitive)
                         (with ^ and $ matching normally) (with . not
                         matching \n) (matching whitespace and #
                         normally):
