直接上代码,逐行对代码进行研究,一定会有所收获。
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
