JS regular expression to verify whether it is a valid 11-digit mobile phone number,

Recently, I have been working on the registration and landing page, which involves the verification of 11-digit valid mobile phone numbers. The code is posted here, hoping to help friends who have this development needs.

[javascript] view plain copy

1. function isPoneAvailable($poneInput) {  
2.           var myreg = / ^ [1] [3,4,5,7,8] [0-9] {9} $ /;  
3.           if (!myreg.test($poneInput.val())) {  
4.               return false;  
5.           } else {  
6.               return true;  
7.           }  
8.       }  

Here I directly encapsulate it in a method, and when needed, pass in an input jq object. Of course, you can also pass in strings directly, like:

[javascript] view plain copy

1. function isPoneAvailable(str) {  
2.           var myreg = / ^ [1] [3,4,5,7,8] [0-9] {9} $ /;  
3.           if (!myreg.test(str)) {  
4.               return false;  
5.           } else {  
6.               return true;  
7.           }  
8.       }  

The point here is this regular expression:

[javascript] view plain copy

1. var myreg = / ^ [1] [3,4,5,7,8] [0-9] {9} $ /;  

This expression means:

1--begins with 1;

2--The second digit can be any one of 3, 4, 5, 7, 8;

3--finally ends with 9 integers from 0-9.

 

Originally, it only accommodates mobile phone numbers starting with 13, 15, 17, 18, but the test mm says that there are numbers starting with 14, so 14 is added; of course, if it develops into numbers starting with 16, or 19, etc. ,exist

1. [3,4,5,7,8]  

can be added in.
