What does "/g" mean in regular expressions (/[^0-9]/g, ")? After the expression plus the parameter G, it indicates that a global match can be made, noting the meaning of "can" here. We describe in detail:1) for the Exec method of an expression object, without adding g, only the first match is returned, regardless of how many times it is executed, and if you join G, the firs
