javascript 中日期类型处理浅谈

由于要用到js前端判断日期类型数据,所以,在网上Google了一把,但,都上面的方法都不是很理想.
一次偶然的机会,在网上找到了一位仁兄贴出来的,判断function.
以下是我修改过的function.
function isDate(strDate)
{
    var reg = /^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2}) (\d{1,2}):(\d{1,2}):(\d{1,2})$/;
    var r = s.match(reg);
    if(r==null)return false;
    //var d= new Date(r[1], --r[3],r[4],r[5],r[6]); //格式:2007-3-2 18:23
    var d= new Date(r[1], --r[3],r[4],r[5],r[6],r[7]);
    if(d.getFullYear()!=Number(r[1]))return false;//判断年份
    if(d.getMonth()!=Number(r[3]))return false;//判断月份
    if(d.getDate()!=Number(r[4]))return false;//判断日期
    if(d.getHours()!=Number(r[5]))return false;//判断小时
    if(d.getMinutes()!=Number(r[6]))return false;//判断分
    if(d.getSeconds()!=Number(r[7]))return false;//判断秒
    return true;
}

到目前,我还不能完整的说出r[1]到r[6]的由来,为了增加判断时间中秒的部分,我增加了reg是最后的"}):(\d{1,2})"部分,d中的r[7],以及"if(d.getSeconds()!=Number(r[7]))return false;//判断秒"

各方法解释如参考资料.
