chinese-idcard-checker's Issues

15位身份证号码处理

/**
* 身份证15位18位互转
* @param {string} oldCard - 身份证号码
* @return 18或15位身份证号码
*/
IDCardChecker.prototype.getIDCard = function (oldCard) {
try {
if (oldCard.length == 18) {
var strZJHM = oldCard.substr(0, 6) + oldCard.substr(8, 9);
return strZJHM.toLocaleUpperCase();
}
else if (oldCard.length == 15) {
var w = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2];
var a = ["1", "0", "X", "9", "8", "7", "6", "5", "4", "3", "2"];
var strZJHM = oldCard.substr(0, 6) + "19" + oldCard.substr(6);
var v_Sum = 0;
for (var i = 0; i < strZJHM.length; i++) {
v_Sum = v_Sum + Number(strZJHM.substr(i, 1)) * w[i];
}
var ai = v_Sum % 11;
strZJHM = strZJHM + a[ai];
return strZJHM.toLocaleUpperCase();
}
else {
throw new Error('身份证格式错误！');
}
}
catch (e) {
throw new Error('身份证格式错误！');
}
};

safari 下获取生日失败

原因在于这段

chinese-idcard-checker/src/IDCardChecker.ts

Lines 187 to 196 in e3e930d

getBirthDate(idCardNum: string): Date | null {
if (this.validate(idCardNum)) {
const birthDate = idCardNum.substring(6, 14);
const year = this.getYear(birthDate);
const month = this.getMonth(birthDate);
const date = this.getDay(birthDate);
return new Date(`${year}-${month}-${date}`);
}
return null;
}

chinese-idcard-checker/src/IDCardChecker.ts

Lines 77 to 80 in e3e930d

const date = this.getDay(dateString);
const fullDate = new Date(`${year}-${month}-${date}`);
if (fullDate && fullDate.getMonth() === month - 1) {
return true; 

return new Date(`${year}-${month}-${date}`);

如果生日是单为数

比如 2000-1-1，在 safari 下 new Date('2000-1-1') 会抛出异常

把 0 补齐就没问题 new Date('2000-01-01')
