1. XXX-XXX-XXXX
2. XXXXXXXXXX

I want to use a regular expression of the format. I tried as shown below, and an error occurs. How do I fix it?

---

1. sample var regExp = / ^ 01 ([0 | 1 | 6 | 7 | 8 | 9]?) - ([0-9] {3}) - ([0-9] {4}) $ /??;
2. sample var regExp = / ^ 01 ([0 | 1 | 6 | 7 | 8 | 9]?) ([0-9] {3}) ([0-9] {4}) $ /??;

回答1:

sample 1

var regExp = /^01([016789]?)-([0-9]{3})-([0-9]{4})$/;

sample 2

var regExp = /^01([016789]?)[0-9]{3}[0-9]{4}$/;

just make sure you don't have spaces and remove | from [0|1|6|7|8|9]
