话不多说上代码

//身份证号合法性验证
//支持15位和18位身份证号
//支持地址编码、出生日期、校验位验证
function cidInfo(code) {
var city={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:"* ",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"*",71:"*",81:"香港",82:"澳门",91:"国外 "};
var tip = "";
var pass= true; if(!code || !/^\d{6}(18|19|20)?\d{2}(0[1-9]|1[012])(0[1-9]|[12]\d|3[01])\d{3}(\d|X)$/i.test(code)){
tip = "身份证号格式错误";
pass = false;
} else if(!city[code.substr(0,2)]){
tip = "地址编码错误";
pass = false;
}
else{
//18位身份证需要验证最后一位校验位
if(code.length == 18){
code = code.split('');
//∑(ai×Wi)(mod 11)
//加权因子
var factor = [ 7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2 ];
//校验位
var parity = [ 1, 0, 'X', 9, 8, 7, 6, 5, 4, 3, 2 ];
var sum = 0;
var ai = 0;
var wi = 0;
for (var i = 0; i < 17; i++)
{
ai = code[i];
wi = factor[i];
sum += ai * wi;
}
var last = parity[sum % 11];
if(parity[sum % 11] != code[17]){
tip = "校验位错误";
pass =false;
}
}
}
//if(!pass) alert(tip);
return pass;
}
//身份证判断
function is_sfzh() {
var ddlZjtype = $('#ddlZjtype').val();
if (ddlZjtype == '居民身份证') {
var sfzh = $('#sfzh').val(); // 身份证号码为15位或者18位,15位时全为数字,18位前17位为数字,最后一位是校验位,可能为数字或字符X
var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/;
if (reg.test(sfzh) === false) {
alert("身份证输入不合法");
$('#sfzh').val('');
return false;
}
}
}

包含验证 15位身份证 及18位身份证及最后数字的验证,很全的,拿走吧
