[Solved] jquery validate a comma separated list of integers

by


You 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
