How jQuery uses regular expressions to verify mobile phone number, ID number, and Chinese name

Number judgment method: isNaN() function

test() method judges whether the regular expression content is matched in the string, and returns a boolean value (true / false)

// 验证中文名称 
function isChinaName(name) 
{ var pattern = /^[\u4E00-\u9FA5]{1,6}$/; 
return pattern.test(name); } 
// 验证手机号 
function isPhoneNo(phone) { 
var pattern = /^1[34578]\d{9}$/; 
return pattern.test(phone); } 
// 验证身份证 
function isCardNo(card) { 
var pattern = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/; 
return pattern.test(card); }
