详细校验规则
-
省级地址码校验
checkProv = function (val) { var pattern = /^[1-9][0-9]/; var provs = {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"}; if (pattern.test(val)) { if(provs[val]) { return true; } } return false; } //输出 true,37是山东 console.log(checkProv(37)); //输出 false,16不存在 console.log(checkProv(16));
-
出生日期码校验
var checkDate = function (val) { var pattern = /^(18|19|20)\d{2}((0[1-9])|(1[0-2]))(([0-2][1-9])|10|20|30|31)$/; if(pattern.test(val)) { var year = val.substring(0, 4); var month = val.substring(4, 6); var date = val.substring(6, 8); var date2 = new Date(year+"-"+month+"-"+date); if (date2 && date2.getMonth() == (parseInt(month) - 1)) { return true; } } return false; } //输出 true console.log(checkDate("20180212")); //输出 false 2月没有31日 console.log(checkDate("20180231"));

校验码校验
var checkCode = function (val) { var p = /^[1-9]\d{5}(18|19|20)\d{2}((0[1-9])|(1[0-2]))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$/; var factor = [ 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2 ]; var parity = [ 1, 0, 'X', 9, 8, 7, 6, 5, 4, 3, 2 ]; var code = val.substring(17); if (p.test(val)) { var sum = 0; for(var i=0;i<17;i++) { sum += val[i]*factor[i]; } if(parity[sum % 11] == code.toUpperCase()) { return true; } } return false; } // 输出 true, 校验码相符 console.log(checkCode("11010519491231002X")); // 输出 false, 校验码不符 console.log(checkCode("110105194912310021"));

整体校验代码
var checkID = function (val) { if(checkCode(val)) { var date = val.substring(6,14); if(checkDate(date)) { if(checkProv(val.substring(0,2))) { return true; } } } return false; } //输出 true console.log(checkID("11010519491231002X")); //输出 false,校验码不符 console.log(checkID("110105194912310021")); //输出 false,日期码不符 console.log(checkID("110105194902310026")); //输出 false,地区码不符 console.log(checkID("160105194912310029"));
