<script>
function getRecentDay(day){
var today = new Date();
var targetday_milliseconds=today.getTime() + 1000*60*60*24*day;
today.setTime(targetday_milliseconds);
var tYear = today.getFullYear();
var tMonth = today.getMonth();
var tDate = today.getDate();
tMonth = doHandleMonth(tMonth + 1);
tDate = doHandleMonth(tDate);
return tYear+"-"+tMonth+"-"+tDate;
}
function doHandleMonth(month){
var m = month;
if(month.toString().length == 1){
m = "0" + month;
}
return m;
}
console.log("半年前："+getRecentDay(-180));
console.log("三月前："+getRecentDay(-90));
console.log("一月前："+getRecentDay(-30));
console.log("昨天："+getRecentDay(-1));
console.log("今天："+getRecentDay(0));
console.log("明天："+getRecentDay(1));
console.log("后天："+getRecentDay(2));
console.log("一月后："+getRecentDay(30));
console.log("三月后："+getRecentDay(90));
console.log("半年后："+getRecentDay(180));
