I have a form where the user is asked to enter a comma separated list of numbers (integers). How do I check their input with jquery during validation to verify that they have only entered numbers and commas?

See Question&Answers more detail:osYou can evaluate the input (single digits) with this Regex:
^[0-9](,[0-9])*$
For long numbers, the regex is:
^[0-9]+(,[0-9]+)*$
It forces user to avoid blanks or tabs.
To allow 0248 but not 00558, the new regex is:
^(([0]?[1-9][0-9]*)|[0])(,(([0]?[1-9][0-9]*)|[0]))*$
you can test it on regex101 here
