数据格式验证

1. 身份证

    function isCardID(sId) {
        var iSum = 0;
        var info = "";
        if (!/^d{17}(d|x)$/i.test(sId)) {
            alertFrame("你输入的身份证长度或格式错误", 3);
            return false;
        }
        sId = sId.replace(/x$/i, "a");
        if (aCity[parseInt(sId.substr(0, 2))] == null) {
            alertFrame("你的身份证地区非法", 3);
            return false;
        }
        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())) {
            alertFrame("身份证上的出生日期非法", 3);
            return false;
        }
        for (var i = 17; i >= 0; i--) iSum += (Math.pow(2, i) % 11) * parseInt(sId.charAt(17 - i), 11);
        if (iSum % 11 != 1) {
            alertFrame("你输入的身份证号非法", 3);
            return false;
        }
        //aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女");//此次还可以判断出输入的身份证号的人性别
        return true;
    }
