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:"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 "};
  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
