I need to match a string like 2431-72367, i.e., a string with at least one number before and after the dash and only one dash.
I need to check it in JavaScript. Can anyone give me the regex and explain it?
/^\d+-\d+$/will work.^signals the begin of the string.\d+means one or more digits.$signals the end of the string.As a result,
/^\d+-\d+$/.test("2431-72367")returns true.
