- 嚴格的身份證校驗
export const isCardID = (sId) => {
if (!/(^\d{15}$)|(^\d{17}(\d|X|x)$)/.test(sId)) {
console.log('你輸入的身份證長度或格式錯誤')
return false
}
//身份證城市
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: "雲南", 54: "西藏", 61: "陝西", 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(sId.substr(0, 2))]) {
console.log('你的身份證地區非法')
return false
}
// 出生日期驗證
var sBirthday = (sId.substr(6, 4) + "-" + Number(sId.substr(10, 2)) + "-" + Number(sId.substr(12, 2))).replace(/-/g, "/"),
d = new Date(sBirthday)
if (sBirthday != (d.getFullYear() + "/" + (d.getMonth() + 1) + "/" + d.getDate())) {
console.log('身份證上的出生日期非法')
return false
}
// 身份證號碼校驗
var sum = 0,
weights = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2],
codes = "10X98765432"
for (var i = 0; i < sId.length - 1; i++) {
sum += sId[i] * weights[i];
}
var last = codes[sum % 11]; //計算出來的最後一位身份證號碼
if (sId[sId.length - 1] != last) {
console.log('你輸入的身份證號非法')
return false
}
return true
}
上面類似的校驗方法還有很多，這裏提供的是一些常用，希望對大家有幫助！
