javascript实现验证身份证号的有效性并提示
function nunber(allowancePersonValue){ 
 if(allowancePersonValue=="身份证号"){ 
 $("#span_username").show(); 
 $("#span_username").html("身份证号不能为空"); 
 return false; 
 } 
 //校验长度,类型 
 else if(isCardNo(allowancePersonValue) === false) 
 { 
$("#span_username").show(); 
 $("#span_username").html("您输入的身份证号码不正确,请重新输入"); 
 return false; 
 } 
 //检查省份 
 else if(checkProvince(allowancePersonValue) === false) 
 { 
 $("#span_username").show(); 
 $("#span_username").html("您输入的身份证号码不正确,请重新输入"); 
 return false; 
 } 
 //校验生日 
 else if(checkBirthday(allowancePersonValue) === false) 
 { 
 $("#span_username").show(); 
 $("#span_username").html("您输入的身份证号码生日不正确,请重新输入"); 
 return false; 
 } 
 //检验位的检测 
 else if(checkParity(allowancePersonValue) === false) 
 { 
 $("#span_username").show(); 
 $("#span_username").html("您的身份证校验位不正确,请重新输入"); 
 return false; 
 }else{ 
 $("#span_username").hide(); 
 return true; 
 } 
 
} 
 
//身份证省的编码 
var vcity={ 11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古", 
    21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏", 
    33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南", 
    42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆", 
    51:"四川",52:"贵州",53:"云南",54:"*",61:"陕西",62:"甘肃", 
    63:"青海",64:"宁夏",65:"*",71:"*",81:"香港",82:"澳门",91:"国外" 
    }; 
 
//检查号码是否符合规范,包括长度,类型 
function isCardNo(card){ 
 //身份证号码为15位或者18位,15位时全为数字,18位前17位为数字,最后一位是校验位,可能为数字或字符X 
 var reg = /(^\d{15}$)|(^\d{17}(\d|X)$)/; 
 if(reg.test(card) === false){ 
 //alert("demo"); 
 return false; 
 } 
 return true; 
} 
 
//取身份证前两位,校验省份 
function checkProvince(card){ 
 var province = card.substr(0,2); 
 if(vcity[province] == undefined){ 
 return false; 
 } 
 return true; 
} 
 
//检查生日是否正确 
function checkBirthday(card){ 
 var len = card.length; 
 //身份证15位时,次序为省(3位)市(3位)年(2位)月(2位)日(2位)校验位(3位),皆为数字 
 if(len == '15'){ 
   var re_fifteen = /^(\d{6})(\d{2})(\d{2})(\d{2})(\d{3})$/; 
   var arr_data = card.match(re_fifteen); 
   var year = arr_data[2]; 
   var month = arr_data[3]; 
   var day = arr_data[4]; 
   var birthday = new Date('19'+year+'/'+month+'/'+day); 
   return verifyBirthday('19'+year,month,day,birthday); 
 } 
 //身份证18位时,次序为省(3位)市(3位)年(4位)月(2位)日(2位)校验位(4位),校验位末尾可能为X 
 if(len == '18'){ 
   var re_eighteen = /^(\d{6})(\d{4})(\d{2})(\d{2})(\d{3})([0-9]|X)$/; 
   var arr_data = card.match(re_eighteen); 
   var year = arr_data[2]; 
   var month = arr_data[3]; 
   var day = arr_data[4]; 
   var birthday = new Date(year+'/'+month+'/'+day); 
   return verifyBirthday(year,month,day,birthday); 
 } 
 return false; 
} 
 
//校验日期 
function verifyBirthday(year,month,day,birthday){ 
 var now = new Date(); 
 var now_year = now.getFullYear(); 
 //年月日是否合理 
 if(birthday.getFullYear() == year && (birthday.getMonth() + 1) == month && birthday.getDate() == day) 
 { 
   //判断年份的范围(3岁到100岁之间) 
   var time = now_year - year; 
   if(time >= 3 && time 

使用方法:


效果为输入身份证号,焦掉移开后自动验证,并返回信息!
