jquery verification of mobile phone numbers and formatting examples

We commonly used to verify the phone number of JS

--jquery Mobile phone Number verification

Cell Phone verification

function Ismobil (s)

{

//var reg=/^ ((13[0-9)) | ( 15[^4,\D]) | (18[0,5-9]) \d{8}$/;

var reg=/^1\d{10}$/;

if (!reg.exec (s)) {return

false;

}

return true;

}

* Input box, can only enter numbers;
* In the process of input to display the contents of the input synchronously;
* Determine whether the input mobile phone number is in the correct format;
* To judge the place where the mobile phone belongs;
