javascript实现的距离现在多长时间后的一个格式化的日期

复制代码 代码如下:

function getoneFormatDate(timeLong,formatString)
{
timeLong=parseInt(timeLong);
timeLong=timeLong*1000;
var myDate=new Date();
var futureDate=new Date(parseInt(myDate.getTime())+timeLong);
var year=futureDate.getYear();
var month=futureDate.getMonth();
var day=futureDate.getDate();
var hour=futureDate.getHours();
var minute=futureDate.getMinutes();
var second=futureDate.getSeconds();

if(hour<10)
{
hour="0"+hour;
}
if(minute<10)
{
minute="0"+minute;
}
if(second<10)
{
second="0"+second;
}
formatString=formatString.replace("YYYY",year);
formatString=formatString.replace("MM",month);
formatString=formatString.replace("DD",day);
formatString=formatString.replace("hh",hour);
formatString=formatString.replace("mm",minute);
formatString=formatString.replace("ss",second);
return formatString;
}
