本文實(shí)例講述了JS實(shí)現(xiàn)的驗(yàn)證身份證及獲取地區(qū)功能。分享給大家供大家參考，具體如下：

這里的代碼可以用來(lái)驗(yàn)證身份證號(hào)，并且根據(jù)身份證號(hào)來(lái)判斷是哪個(gè)省份及性別

代碼示例：

<head >  <title></title>  <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script></head><body>  <form id="form1" >  <label>    身份證號(hào)：</label><input type="text" id="txtId" />  <input type="button" value="驗(yàn)證" onclick="CheckId()" />  </form></body></html><script type="text/javascript">  //定義地區(qū)數(shù)組  var CityArray = { 11: "北京", 12: "天津", 13: "河北", 14: "山西", 15: "內(nèi)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(tái)灣", 81: "香港", 82: "澳門", 91: "國(guó)外" }  //驗(yàn)證身份證及返回地區(qū)、出生年月、性別  function CheckIdCard(sId) {    if (sId.length == 15) {      sId = sId.replace(/([/d]{6})(/d{9})/, "$119$2x");    }    var iSum = 0    var info = ""    if (!/^/d{17}(/d|x)$/i.test(sId)) return "非法的身份證號(hào)";    sId = sId.replace(/x$/i, "a");    if (CityArray[parseInt(sId.substr(0, 2))] == null) return "Error:非法地區(qū)";    sBirthday = sId.substr(6, 4) + "-" + Number(sId.substr(10, 2)) + "-" + Number(sId.substr(12, 2));    var d = new Date(sBirthday.replace(/-/g, "/"))    if (sBirthday != (d.getFullYear() + "-" + (d.getMonth() + 1) + "-" + d.getDate())) return "Error:非法生日";    for (var i = 17; i >= 0; i--) iSum += (Math.pow(2, i) % 11) * parseInt(sId.charAt(17 - i), 11)    if (iSum % 11 != 1) return "Error:非法證號(hào)";    return CityArray[parseInt(sId.substr(0, 2))] + "," + sBirthday + "," + (sId.substr(16, 1) % 2 ? "男" : "女")  }  //調(diào)用驗(yàn)證方法  function CheckId() {    var id = $("#txtId").val();    if (id != "") {      alert(CheckIdCard(id));    }  }</script>

PS：這里再為大家提供2款非常方便的正則表達(dá)式工具供大家參考使用：

希望本文所述對(duì)大家JavaScript程序設(shè)計(jì)有所幫助。
