js日期格式“补零”

js 代码：

var day=0;
var month=0;
var year=0;
var today="";
mydate=new Date();
mymonth=mydate.getMonth()+1;
myday= mydate.getDate();
myyear= mydate.getFullYear();
year=(myyear > 200) ? myyear : 1900 + myyear;
if(mymonth >= 10){mymonth=mymonth;}else{mymonth="0" + mymonth;}
if(myday >= 10){myday=myday;}else{myday="0" + myday;}
today=year+'-'+mymonth+'-'+myday;

调用：$("#applydate").val(today);

呵呵，同时要加载jquery插件
