如果把身份證號碼傳到頁面上,在前端頁面獲取年齡就需要用到JS腳本了:
示例:
let age = GetAge('110101199003070337')
function GetAge(identityCard) {
var len = (identityCard + "").length;
if (len == 0) {
return 0;
} else {
if ((len != 15) && (len != 18))//身份證號碼只能爲15位或18位其它不合法
{
return 0;
}
}
var strBirthday = "";
if (len == 18)//處理18位的身份證號碼從號碼中得到生日和性別代碼
{
strBirthday = identityCard.substr(6, 4) + "/" + identityCard.substr(10, 2) + "/" + identityCard.substr(12, 2);
}
if (len == 15) {
strBirthday = "19" + identityCard.substr(6, 2) + "/" + identityCard.substr(8, 2) + "/" + identityCard.substr(10, 2);
}
//時間字符串裏,必須是“/”
var birthDate = new Date(strBirthday);
var nowDateTime = new Date();
var age = nowDateTime.getFullYear() - birthDate.getFullYear();
//再考慮月、天的因素;.getMonth()獲取的是從0開始的,這裏進行比較,不需要加1
if (nowDateTime.getMonth() < birthDate.getMonth() || (nowDateTime.getMonth() == birthDate.getMonth() && nowDateTime.getDate() < birthDate.getDate())) {
age--;
}
return age;
}
