以下是身份证验证代码，想实现验证通过后：点击文本框出生日期、性别，可以自动显示出来，先谢谢了
身份证号码：<input type="text" size="20" id="asidinput" onkeyup="this.value=ignoreSpaces(this.value)" value=""
onblur="alert(cidInfo(asidinput.value))" />出生日期:<input type="text" maxlength="10" name="sBirthday" style="width:
91px"/>性别:<input type="text" maxlength="4" name="ssex" style="width: 41px"/>
<script type="text/javascript" language="javascript">
var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江
苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重
庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳
门",91:"国外"}
function cidInfo(sId){
var iSum=0
var info=""
if(!/^\d{17}(\d|x)$/i.test(sId))return "Error:校验失败！";
sId=sId.replace(/x$/i,"a");
if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区！";
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:非法身份证号！";
return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女")
}
function ignoreSpaces(string) {
var temp = "";
string = '' + string;
splitstring = string.split(" ");
for(i = 0; i < splitstring.length; i++)
temp += splitstring[i];
return temp;
}
</script>

验证通过后，截取身份证的第7位到第14位，为生日。身份证号的倒数第二位为性别，偶数为女性，奇数为男性。
