Phone controller. How to fix?

Question

Regular Expressions

Good afternoon.
Phone number template in a single form
[phone]
Regular /[+7]([0-9]{10})$/
Works, but it works without the last character, i. 9 digits after +7.
How to fix?)

Answer 1

you have [+7]
either "plus" or "7" written, the
regular season sees "plus" and then [0-9]{10}- ten digits
, and what confuses you now?
