Node.js中怎么通過身份證號驗證年齡,很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
node.js實現
static validateIdNumberToAgeYear(str){ let date = new Date(); let currentYear = date.getFullYear(); let currentMonth = date.getMonth() + 1; let currentDate = date.getDate(); let idxSexStart = str.length == 18 ? 16 : 14; let birthYearSpan = str.length == 18 ? 4 : 2; let year; let month; let day; let sex; let birthday; let age; //性別 let idxSex = 1 - str.substr(idxSexStart, 1) % 2; sex = idxSex == '1' ? '女' : '男'; //生日 year = (birthYearSpan == 2 ? '19' : '') + str.substr(6, birthYearSpan); month = str.substr(6 + birthYearSpan, 2); day = str.substr(8 + birthYearSpan, 2); birthday = year + '-' + month + '-' + day; //年齡 let monthFloor = (currentMonth < parseInt(month,10) || (currentMonth == parseInt(month,10) && currentDate < parseInt(day,10))) ? 1 : 0; age = currentYear - parseInt(year,10) - monthFloor; // console.log("我的出生日期是"+year+"年"+month+"月"+day+"日"+",今年"+age+"歲了"+",性別是"+sex); if(age >= 18){ return true; } return false; }
我這里只是做了一個年齡的判斷。
利用js也可以實現
1. 自定義js類如下:
// 構造函數,變量為15位或者18位的身份證號碼 function clsIDCard(CardNo) { this.Valid = false; this.ID15 = ''; this.ID18 = ''; this.Local = ''; if (CardNo != null) this.SetCardNo(CardNo); } // 設置身份證號碼,15位或者18位 clsIDCard.prototype.SetCardNo = function(CardNo) { this.ID15 = ''; this.ID18 = ''; this.Local = ''; CardNo = CardNo.replace(" ", ""); var strCardNo; if (CardNo.length == 18) { pattern = /^\d{17}(\d|x|X)$/; if (pattern.exec(CardNo) == null) return; strCardNo = CardNo.toUpperCase(); } else { pattern = /^\d{15}$/; if (pattern.exec(CardNo) == null) return; strCardNo = CardNo.substr(0, 6) + '19' + CardNo.substr(6, 9) strCardNo += this.GetVCode(strCardNo); } this.Valid = this.CheckValid(strCardNo); } // 校驗身份證有效性 clsIDCard.prototype.IsValid = function() { return this.Valid; } // 返回生日字符串,格式如下,1981-10-10 clsIDCard.prototype.GetBirthDate = function() { var BirthDate = ''; if (this.Valid) BirthDate = this.GetBirthYear() + '-' + this.GetBirthMonth() + '-' + this.GetBirthDay(); return BirthDate; } // 返回生日中的年,格式如下,1981 clsIDCard.prototype.GetBirthYear = function() { var BirthYear = ''; if (this.Valid) BirthYear = this.ID18.substr(6, 4); return BirthYear; } // 返回生日中的月,格式如下,10 clsIDCard.prototype.GetBirthMonth = function() { var BirthMonth = ''; if (this.Valid) BirthMonth = this.ID18.substr(10, 2); if (BirthMonth.charAt(0) == '0') BirthMonth = BirthMonth.charAt(1); return BirthMonth; } // 返回生日中的日,格式如下,10 clsIDCard.prototype.GetBirthDay = function() { var BirthDay = ''; if (this.Valid) BirthDay = this.ID18.substr(12, 2); return BirthDay; } // 返回性別,1:男,0:女 clsIDCard.prototype.GetSex = function() { var Sex = ''; if (this.Valid) Sex = this.ID18.charAt(16) % 2; return Sex; } // 返回15位身份證號碼 clsIDCard.prototype.Get15 = function() { var ID15 = ''; if (this.Valid) ID15 = this.ID15; return ID15; } // 返回18位身份證號碼 clsIDCard.prototype.Get18 = function() { var ID18 = ''; if (this.Valid) ID18 = this.ID18; return ID18; } // 返回所在省,例如:上海市、浙江省 clsIDCard.prototype.GetLocal = function() { var Local = ''; if (this.Valid) Local = this.Local; return Local; } clsIDCard.prototype.GetVCode = function(CardNo17) { var Wi = new Array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2, 1); var Ai = new Array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2'); var cardNoSum = 0; for (var i = 0; i < CardNo17.length; i++) cardNoSum += CardNo17.charAt(i) * Wi[i]; var seq = cardNoSum % 11; return Ai[seq]; } clsIDCard.prototype.CheckValid = function(CardNo18) { if (this.GetVCode(CardNo18.substr(0, 17)) != CardNo18.charAt(17)) return false; if (!this.IsDate(CardNo18.substr(6, 8))) return false; var aCity = { 11 : "北京", 12 : "天津", 13 : "河北", 14 : "山西", 15 : "內蒙古", 21 : "遼寧", 22 : "吉林", 23 : "黑龍江 ", 31 : "上海", 32 : "江蘇", 33 : "浙江", 34 : "安徽", 35 : "福建", 36 : "江西", 37 : "山東", 41 : "河南", 42 : "湖北 ", 43 : "湖南", 44 : "廣東", 45 : "廣西", 46 : "海南", 50 : "重慶", 51 : "四川", 52 : "貴州", 53 : "云南", 54 : "西藏 ", 61 : "陜西", 62 : "甘肅", 63 : "青海", 64 : "寧夏", 65 : "新疆", 71 : "臺灣", 81 : "香港", 82 : "澳門", 91 : "國外" }; if (aCity[parseInt(CardNo18.substr(0, 2))] == null) return false; this.ID18 = CardNo18; this.ID15 = CardNo18.substr(0, 6) + CardNo18.substr(8, 9); this.Local = aCity[parseInt(CardNo18.substr(0, 2))]; return true; } clsIDCard.prototype.IsDate = function(strDate) { var r = strDate.match(/^(\d{1,4})(\d{1,2})(\d{1,2})$/); if (r == null) return false; var d = new Date(r[1], r[2] - 1, r[3]); return (d.getFullYear() == r[1] && (d.getMonth() + 1) == r[2] && d .getDate() == r[3]); }
2. 頁面只需要new出對象,并傳遞數據驗證,并可獲得相關數據( 住址 | 出生日期 | 性別 )即可:
$("#cardNo").blur(function(event){ var idCard = $(this).val(); var checkFlag = new clsIDCard(idCard); if( !checkFlag.IsValid() ){ alert("身份證錯誤"); return false; }else{ alert( "出生于: " + checkFlag.GetBirthDate() +" 地區:" + checkFlag.GetLocal() +" sex:" + checkFlag.GetSex() ); } });
