Two verification methods implemented by javascript or asp to determine whether the ID number is correct

The specific code is as follows:

1. Use javascript to verify:

Copy the code The code is as follows: function checkIdcard(idcard){ var Errors=new Array( "Verification passed!", "Incorrect number of digits in ID number!", "The date of birth of the ID card number is out of the range or contains illegal characters!", "The ID card number is verified incorrectly!", "The ID card area is illegal!" ); var area= {11:"Beijing",12:"Tianjin",13:"Hebei",14:"Shanxi",15:"Inner Mongolia",21:"Liaoning",22:"Jilin",23:"Heilongjiang",31 :"Shanghai",32:"Jiangsu",33:"Zhejiang",34:"Anhui",35:"Fujian",36:"Jiangxi",37:"Shandong",41:"Henan",42:" Hubei",43:"Hunan",44:"Guangdong",45:"Guangxi",46:"Hainan",50:"Chongqing",51:"Sichuan",52:"Guizhou",53:"Yunnan" ,54:"Tibet",61:"Shaanxi",62:"Gansu",63:"Qinghai",64:"Ningxia",65:"Xinjiang",71:"Taiwan",81:"Hong Kong",82 :"Macau",91:"foreign"}
