我这段JS判断到底是错在哪里。

我在网上找了一段判断身份证的JS代码。

 <Script language="javascript"> 
//检查号码是否符合规范,包括长度,类型  
function isCardNo(card)  
{  
    //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}$)|(^\d{17}(\d|X)$)/;  
    if(reg.test(card) == false)  
    {  
        return false;  
    }  
};  

//取身份证前两位,校验省份  
function checkProvince(card)  
{  
    var province = card.substr(0,2);  
    if(vcity[province] == undefined)  
    {  
        return false;  
    }  
};  

//检查生日是否正确  
function checkBirthday(card)  
{  
    var len = card.length;  
    //身份证15位时,次序为省(3位)市(3位)年(2位)月(2位)日(2位)校验位(3位),皆为数字  
    if(len == '15')  
    {  
        var re_fifteen = /^(\d{6})(\d{2})(\d{2})(\d{2})(\d{3})$/;   
        var arr_data = card.match(re_fifteen);  
        var year = arr_data[2];  
        var month = arr_data[3];  
        var day = arr_data[4];  
        var birthday = new Date('19'+year+'/'+month+'/'+day);  
        return verifyBirthday('19'+year,month,day,birthday);  
    }  
    //身份证18位时,次序为省(3位)市(3位)年(4位)月(2位)日(2位)校验位(4位),校验位末尾可能为X  
    if(len == '18')  
    {  
        var re_eighteen = /^(\d{6})(\d{4})(\d{2})(\d{2})(\d{3})([0-9]|X)$/;  
        var arr_data = card.match(re_eighteen);  
        var year = arr_data[2];  
        var month = arr_data[3];  
        var day = arr_data[4];  
        var birthday = new Date(year+'/'+month+'/'+day);  
        return verifyBirthday(year,month,day,birthday);  
    }  
    return false;  
};  

//校验日期  
function verifyBirthday(year,month,day,birthday)  
{  
    var now = new Date();  
    var now_year = now.getFullYear();  
    //年月日是否合理  
    if(birthday.getFullYear() == year && (birthday.getMonth() + 1) == month && birthday.getDate() == day)  
    {  
        //判断年份的范围(3岁到100岁之间)  
        var time = now_year - year;  
        if(time >= 3 && time <= 100)  
        {  

        }  
        return false;  
    }  
    return false;  
};  

//校验位的检测  
function checkParity(card)  
{  
    //15位转18位  
    card = changeFivteenToEighteen(card);  
    var len = card.length;

        return card;  
    }  
    return card;  
};          


     function checktishi() 
     {
var vcity={ 11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",

    }  

 if( form1.qq.value!="" ) 
{
 alert("QQ不能为空!");
 form1.qq.focus();
  return false;
 }  
     }

     </Script>




     HTML页面代码

      <form action="save.php" method="post" name="form1" id="form1" onsubmit="return checktishi();">
        <input name="Cardid"  type="text" value="">
        <input name="qq"  type="text" value="">
        </form>

问题: 如果身份证不正确,可以判断出来,但如果身份证填写正确,就直接提交到save.php了,没有再继续对QQ继续判断。 是哪里写错了吗? 高手帮改改哦。

    你贴出来的代码大括号不匹配吧,应该身份证都无法验证,js语法出错了,vcity 这个数组是私有变量,checkProvince访问不到,vcity放checktishi外面或者当参数传入checkProvince

    verifyBirthday函数也写得有问题,正确的日期也没返回true,校验身份证的也有问题,正确也没返回true,qq号不为空验证对比也搞错。。

    一堆的毛病。。。。。。

    你看你获取Card的时候用的是:var card = document.form1.Cardid.value;能获取到说明这种方式是对的
    但你获取QQ的时候用的是:form1.qq.value,为啥不把document加上呢
