正则表达式：双引号之间的数字和逗号交替

Question

I need to create a regex that matches a "1,2,3,10,12312" pattern.

As I understand it would start with /([""']) to match the double quotes but I'm lost when I try to get to the \\d digit and comma alternation.

what would be a valid regex to do that?

Answer 1

You have some choices, one being:

"\d+(?:,\d+)*"

To even allow empty double quotes ( "" ), change the expression to

"\d*(?:,\d+)*"
