Mobile phone number regular expression explanation

Regular expression of phone number (mobile phone number, 3-4 area code, 7-8 live video number, 1-4 extension code)

The code is as follows:	Copy code
(D {11}) | ^ (d {7, 8}) | (d {4} | d {3})-(d {7, 8 }) | (d {4} | d {3})-(d {7, 8 }) -(d {4} | d {3} | d {2} | d {1}) | (d {7, 8 }) -(d {4} | d {3} | d {2} | d {1}) $)

Matching format:
 
11-digit mobile phone number
3-4-bit area code, 7-8 live video numbers, 1-4 ext.
Regular expression -- verify mobile phone number: 13 [0-9] {9}
If the mobile phone number is 86 or + 86 before it is implemented: ^ (+ 86) | (86 ))? (13) d {9} $

Example

The code is as follows:	Copy code
$ Mobilephone = trim ($ _ POST ["smMobilePhone"]); // Regular verification of mobile phone numbers If (preg_match ("/^ 13 [0-9] {1} [0-9] {8} $ | 15 [0189] {1} [0-9] {8} $ | 189 [0-9] {8} $ /", $ mobilephone )){ // Verification passed        } Else { // Incorrect mobile phone number format        }

The above is our previous method. Next we will introduce the latest regular expression for mobile phone numbers.

The current mobile phone number is increased by 150,153,156,158,159,157,188,189.
Therefore, the regular expression is as follows: string s = @ "^ (13 [0-9] | 15 [0 | 3 | 6 | 7 | 8 | 9] | 18 [8 | 9]) d {8} $ ";

Tips of Wan Yahu, adding 180,147, etc., more comprehensive expressions:

The code is as follows:	Copy code
^ (1 ([35] [0-9]) | (47) | [8] [0126789]) d {8} $

 

Modify the 183 and add the landline as follows:

The code is as follows:	Copy code
Mobile phone: ^ (1 ([35] [0-9]) | (47) | [8] [01236789]) d {8} $ Landline: ^ 0d {2, 3 }(-)? D {7, 8} $

Asp.net practices

The code is as follows:

Copy code

Using System; Using System. Collections. Generic; Using System. Text; Using System. Text. RegularExpressions; Using System. Windows. Forms; Namespace ConsoleApplication1 { Class Program     { Static void Main (string [] args)         { // String s = @ "^ (13 [0-9] | 15 [0 | 3 | 6 | 8 | 9]) d {8} $ "; String s = @ "^ (13 [0-9] | 15 [0 | 3 | 6 | 7 | 8 | 9] | 18 [8 | 9]) d {8} $ "; While (true)             { String input = Console. ReadLine (); If (Regex. IsMatch (input, s ))                 { MessageBox. Show ("Exactly! ");                 } Else                 { MessageBox. Show ("No! ");                 }             }         }     } }

A complete instance

You can use the first or second mobile phone number. I don't know if there are more than 15 mobile phone numbers ..

The code is as follows:

Copy code

<Input type = "text" id = "mobile" name = "mobile" onblur = "if (value = '') {value = 'Enter your mobile phone number'} "onfocus =" if (value = 'Enter your mobile phone number ') {value = ''}" value = "enter your mobile phone number"/>     <Input type = "button" name = "china_mobile" value = "check whether the mobile phone number is" onclick = "CheckChinaMobileID (document. getElementById ('mobile'). value)"/>     <Input type = "button" name = "is_mobile" value = "verify whether the mobile phone number is" onclick = "CheckIsMobile (document. getElementById ('mobile '). value) "/> function CheckChinaMobileID (mobile ){         If (mobile = ""){ Alert ("Enter your mobile phone number! "); Return false;         } If (isNaN (mobile) | (mobile. length! = 11 )){ Alert ("The mobile phone number is 11 digits! Please enter it correctly! "); Return false;         } Var reg =/^ 0 {0, 1} (13 [4-9] | 15 [7-9] | 15 [0-2] | 18 [7-8]) [0-9] {8} $ /; If (! Reg. test (mobile ))         { Alert ("Your mobile phone number is not a mobile number. Please enter it again ");             Return false;         } Alert ("Grandpa, this is the mobile phone number "); Return true;     } Function CheckIsMobile (mobile ){         If (mobile = ""){ Alert ("Enter your mobile phone number! "); Return false;         } If (isNaN (mobile) | (mobile. length! = 11 )){ Alert ("The mobile phone number is 11 digits! Please enter it correctly! "); Return false;         }         Var reg =/^ 0 {0, 1} (13 [0-9] | 15 [0-9]) [0-9] {8} $ /; If (! Reg. test (mobile ))         { Alert ("Your mobile phone number is incorrect. Please enter it again ");             Return false;         } Alert ("Grandpa, this is really a mobile phone number. I don't know where it is "); Return true;     }
