jQuery Validation插件的自定义规则（正则表达式）

Question

Can you help me write two rules that check phoneNumber?
First rule: start with +7 or 8 then any ten numbers. Examples:

+77017223457 - valid
77017223457 -not valid
87017223457 - valid

Second rule: start with +7 or 8 then three numbers from set:
{700, 701, 702, 705, 707, 712, 713, 717, 718,721, 725, 726, 727, 777 } then any seven numbers.

Examples:

+77074446255 - valid
+77034446255 - not valid (no 703 in the set)

Thanks.

Answer 1

(?:\+7|8)(?:70[0-2]|705|707|71[23]|71[78]|721|72[5-7]|777)[0-9]+

or, less compressed but more obvious:

(?:\+7|8)(?:700|701|702|705|707|712|713|717|718|721|725|726|727|777)[0-9]+

To make sure that this is not a partial match, use ^ and $

^(?:\+7|8)(?:700|etc|etc)[0-9]+$

Answer 2

var phone = $("#phoneNumber").val()
var regex = /^((\+7)|8)(700|701|702|705|707|712|713|717|718,721|725|726|727|777)[0-9]{7}$/;
if(regex.test(phone))
   // Phone is valid
else
   // Phone is invalid

Answer 3

更加紧凑：

/^(?/\+7|8)7(?:0[01257]|1[2378]|2[1567]|77)\d{7}$/
