Javascript mobile phone number validity verification code set _ javascript skills

The following is the code for verifying the phone number in JS. It is very practical and is the first code for everyone:

The Code is as follows:

Function Checkreg ()
{
// Verify the phone number, including the phone number 153,159
If (document. form. phone. value = "" & document. form. UserMobile. value = ""){
Alert ("You must enter at least one phone number and one mobile phone number! ");
Document. form. phone. focus ();
Return false;
}
If (document. form. phone. value! = ""){
Var phone = document. form. phone. value;
Var p1 =/^ ([0 \ +] \ d {2, 3 }-)? (0 \ d {2, 3 })-)? (\ D {7, 8}) (-(\ d {3 ,}))? $ /;
Var me = false;
If (p1.test (phone) me = true;
If (! Me ){
Document. form. phone. value = '';
Alert ('Sorry, the phone number you entered is incorrect. Use-to separate the area code from the phone number ');
Document. form. phone. focus ();
Return false;
}
}
If (document. form. UserMobile. value! = ""){
Var mobile = document. form. UserMobile. value;
Var reg0 =/^ 13 \ d {5, 9} $ /;
Var reg1 =/^ 153 \ d {4, 8} $ /;
Var reg2 =/^ 159 \ d {4, 8} $ /;
Var reg3 =/^ 0 \ d {10, 11} $ /;
Var my = false;
If (reg0.test (mobile) my = true;
If (reg1.test (mobile) my = true;
If (reg2.test (mobile) my = true;
If (reg3.test (mobile) my = true;
If (! My ){
Document. form. UserMobile. value = '';
Alert ('Sorry, the phone number or PHS number you entered is incorrect. ');
Document. form. UserMobile. focus ();
Return false;
}
Return true;
}
}

Description
The test method checks whether a mode exists in the string. If yes, true is returned. Otherwise, false is returned.

Regular Expression section:
\ D represents a number
{7, 8} stands for 7-8 digits (phone number)
{3,} represents the extension number.
D {2, 3} represents the area code
\ +] \ D {2, 3} represents the international area code
^ 13 \ d {5, 9} $ // 130? 139. At least 5 bits, up to 9 bits
/^ 153 \ d {153} $ // China Unicom. At least 4 bits, at most 8 bits
/^ 159 \ d {159} $ // move. At least 4 bits, at most 8 bits

Second:

The Code is as follows:

Var Mobile = $ ("# varMobilePhone"). val ();
Var Phone = $ ("# varPhoneNo"). val ();
If (Mobile = "" & Phone = "")
{
Alert ("mobile phone and fixed phone, please fill in at least one contact method! ");
$ ("# VarMobilePhone"). focus ();
Return;
}
If (Mobile! = "")
{
If (! IsMobil (Mobile ))
{
Alert ("enter the correct mobile phone number! ");
$ ("# VarMobilePhone"). focus ();
Return ;}
}
// Mobile phone number verification information
Function isMobil (s)
{
Var patrn =/(^ 0 {0, 1} 1 [3 | 4 | 5 | 6 | 7 | 8 | 9] [0-9] {9} $ )/;
If (! Patrn.exe c (s ))
{
Return false;
} Return true ;}
Background verification is as follows:
If (model. Zip! = Null)
{
If (! Common. PageValidate. IsValidate (model. Zip, "^ \ d {6} $ "))
{Common. WebMessage. showMsg (HttpContext. Current, "enter the correct zip code ");
Return;
}
}
If (model. PhoneNo! = Null)
{
If (! Common. pageValidate. isValidate (model. phoneNo, "\ d {3}-\ d {8} | \ d {4}-\ d {7 }"))
{
Common. WebMessage. showMsg (HttpContext. Current, "enter the correct phone number! ");
Return;
}
}
If (model. MobilePhone! = Null)
{
If (! Common. pageValidate. isValidate (model. mobilePhone, "^ 0 {0, 1} (13 [0-9] | 15 [3-9] | 15 [0-2] | 18 [0-9]) [0-9] {8} $ "))
{
Common. WebMessage. showMsg (HttpContext. Current, "enter the correct 11-digit valid mobile phone number! ");
Return;
}
}
