var month = date.getMonth() + 1;
var strDate = date.getDate();
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (strDate >= 0 && strDate <= 9) {
strDate = "0" + strDate;
}
var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
+ " " + date.getHours() + seperator2 + date.getMinutes()
+ seperator2 + date.getSeconds();
return currentdate;
}

strDate = "0" + strDate;
}
if(date.getDay()==0) day = "星期日"
if(date.getDay()==1) day = "星期一"
if(date.getDay()==2) day = "星期二"
