Hi i want to validate a string with in which only numbers are allowed and only one # sign at
the end.I use this but it allow double # sign at end.
/^[0-9]+#/
How i can refine it to only allow single # sign at end of string like 1345#
Don’t use
^and$. Use\Aand\zinstead! It’s a big gotcha!^and$are used to specify the end of the LINE, not sting!I hope it’ll help someone else!
