身份证号校验和社会信用代码校验
如下:
//身份证号校验 function isIdCardNo(num) { num = num.toUpperCase();//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。 if (!(/(^\d{15}$)|(^\d{17}([0-9]|X)$)/.test(num))) { alert('输入的身份证号长度不对,或者号码不符合规定!\n15位号码应全为数字,18位号码末位可以为数字或X。'); //alert('身份证号长度不正确或不符合规定!'); return false; } //验证前2位,城市符合 var aCity={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:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"}; if(aCity[parseInt(num.substr(0,2))]==null){ alert('身份证号不正确或不符合规定!'); return false; } //alert('城市:'+aCity[parseInt(num.substr(0,2))]); //下面分别分析出生日期和校验位 var len, re; len = num.length; if (len == 15) { re = new RegExp(/^(\d{6})(\d{2})(\d{2})(\d{2})(\d{3})$/); var arrSplit = num.match(re); //检查生日日期是否正确 var dtmBirth = new Date('19' + arrSplit[2] + '/' + arrSplit[3] + '/' + arrSplit[4]); var bGoodDay; bGoodDay = (dtmBirth.getYear() == Number(arrSplit[2])) && ((dtmBirth.getMonth() + 1) == Number(arrSplit[3])) && (dtmBirth.getDate() == Number(arrSplit[4])); if (!bGoodDay) { alert('身份证号的出生日期不对!'); return false; } else { //将15位身份证转成18位 //校验位按照ISO 7064:1983.MOD 11-2的规定生成,X可以认为是数字10。 var arrInt = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2); var arrCh = new Array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2'); var nTemp = 0, i; num = num.substr(0, 6) + '19' + num.substr(6, num.length - 6); for(i = 0; i < 17; i ++) { nTemp += num.substr(i, 1) * arrInt[i]; } num += arrCh[nTemp % 11]; return true; } } if (len == 18) { re = new RegExp(/^(\d{6})(\d{4})(\d{2})(\d{2})(\d{3})([0-9]|X)$/); var arrSplit = num.match(re); //检查生日日期是否正确 var dtmBirth = new Date(arrSplit[2] + "/" + arrSplit[3] + "/" + arrSplit[4]); var bGoodDay; bGoodDay = (dtmBirth.getFullYear() == Number(arrSplit[2])) && ((dtmBirth.getMonth() + 1) == Number(arrSplit[3])) && (dtmBirth.getDate() == Number(arrSplit[4])); if (!bGoodDay) { //alert(dtmBirth.getYear()); //alert(arrSplit[2]); alert('身份证号的出生日期不对!'); return false; } else { //检验18位身份证的校验码是否正确。 //校验位按照ISO 7064:1983.MOD 11-2的规定生成,X可以认为是数字10。 var valnum; var arrInt = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2); var arrCh = new Array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2'); var nTemp = 0, i; for(i = 0; i < 17; i ++) { nTemp += num.substr(i, 1) * arrInt[i]; } valnum = arrCh[nTemp % 11]; if (valnum != num.substr(17, 1)) { //alert('18位身份证的校验码不正确!应该为:' + valnum); alert('18位身份证号的校验码不正确!'); return false; } return true; } } return false; } //社会信用识别码校验 function CheckSocialCreditCode(Code){ var patrn = /^[0-9A-Z]+$/; //18位校验及大写校验 if ((Code.length != 18) || (patrn.test(Code) == false)) { alert("不是有效的统一社会信用编码!"); return false; } else { var Ancode; //统一社会信用代码的每一个值 var Ancodevalue; //统一社会信用代码每一个值的权重 var total = 0; var weightedfactors = [1, 3, 9, 27, 19, 26, 16, 17, 20, 29, 25, 13, 8, 24, 10, 30, 28]; //加权因子 var str = '0123456789ABCDEFGHJKLMNPQRTUWXY'; //不用I、O、S、V、Z for (var i = 0; i < Code.length - 1; i++){ Ancode = Code.substring(i, i + 1); Ancodevalue = str.indexOf(Ancode); total = total + Ancodevalue * weightedfactors[i]; //权重与加权因子相乘之和 } var logiccheckcode = 31 - total % 31; if (logiccheckcode == 31){ logiccheckcode = 0; } var Str = "0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,J,K,L,M,N,P,Q,R,T,U,W,X,Y"; var Array_Str = Str.split(','); logiccheckcode = Array_Str[logiccheckcode]; var checkcode = Code.substring(17, 18); if (logiccheckcode != checkcode){ alert("不是有效的统一社会信用编码!"); return false; } return true; } }
