根据身份证获取出生日期及性别

　　第一步：身份证号格式校验

/**
 * 身份证号格式校验
 */
function idValidator(obj) {
    var provinces={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 expression=/(^\d{15}$)|(^\d{17}(\d|X)$)/;
    var isViald=expression.test(obj.value);
    if (isViald)
    {
       isViald=provinces[obj.value.substr(0,2)]?true:false;
    }
    return isViald;
}

　　第二步：通过身份证获取出生日期及性别

/**  
 * 通过身份证获取出生日期及性别
 * @param idCard 15/18位身份证号码   
 * @return JSON对象 
 *         sex：0-女、1-男；
 *         birthDay：yyyy-MM-dd
 */
function getBirthdayAndSex(idCard) {
    var info = {};
    var birth = (idCard.length === 18) ? idCard.slice(6, 14) : idCard.slice(6, 12);
    // 18位：提取第17位数字；15位：提取最后一位数字
    var order = (idCard.length == 18) ? idCard.slice(-2,-1):idCard.slice(-1);
    info.birthDay = (idCard.length === 18) ? ([birth.slice(0, 4),
            birth.slice(4, 6), birth.slice(-2)
            ]).join(‘-‘) : ([
                ‘19‘ + birth.slice(0, 2), birth.slice(2, 4),
                birth.slice(-2)
            ]).join(‘-‘);
    // 余数为0代表女性，不为0代表男性        
    info.sex = (order % 2 === 0 ? 0 : 1);
    return info;        
}

　　第三步：改变出生日期及性别的值及只读状态

/**
 * 改变出生日期及性别的值及只读状态
 */
function changeCardInfo(obj) {
    
    if ("" == obj.value && !document.getElementById(‘BIRTH_DAY2‘).disabled)
        return;
    
    // 格式校验结果
    var result = idValidator(obj);
    if (result) {
        // 获取出生日期及性别
        var cardInfo = getBirthdayAndSex(obj.value);
        var birthDay = cardInfo.birthDay;
        var sex = cardInfo.sex;
        
        document.getElementById(‘BIRTH_DAY2‘).disabled = true;
        document.getElementById(‘BIRTH_DAY2‘).value = birthDay;
        document.getElementById(‘BIRTH_DAY‘).value = birthDay;
        
        document.getElementById(‘male‘).disabled = true;
        document.getElementById(‘female‘).disabled = true;
        
        if (1 == sex) {
            document.getElementById(‘male‘).checked = true;
            document.getElementById(‘SEX‘).value = ‘男‘;
        } else {
            document.getElementById(‘female‘).checked = true;    
            document.getElementById(‘SEX‘).value = ‘女‘;
        }
    } else {//重置
        document.getElementById(‘BIRTH_DAY‘).value = "";
        document.getElementById(‘BIRTH_DAY2‘).value = "";
        document.getElementById(‘BIRTH_DAY2‘).disabled = false;
        document.getElementById(‘male‘).disabled = false;
        document.getElementById(‘female‘).disabled = false;
        document.getElementById(‘male‘).checked = true;
        document.getElementById(‘SEX‘).value = ‘男‘;
    }
    
}
