Validate phone and cell number

  • 772

I am validating a field that can be a telephone number or cell phone number, but when placing the value it accepts me from 7 to 9, I want it to be validated only if it has 7 or 9 characters. How can i fix it?

\d{7,9}

Code

$(document).ready(function () {

var telefono = $("#campo_telefono")

var expreg = /\d{7,9}/;

if (expreg.test(telefono))
    alert("El telefono es correcta");
else
    alert("El telefono NO es correcta"); 
});
javascript

    This expression is valid: only digits from 0 to 9 and between braces ({N, M}) range of number of digits; example: from 7 to 9 digits.

    ^[0-9]{7,9}$

    If you need only a number of digits; example: only 7 digits.

    ^[0-9]{7}$

    If you need number of exact digits; example: only 7 or 9 digits.

    ^(\\d{7}|\\d{9})$
