<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title> JS获取最近三天和最近3天日期</title>
</head>
<body>
<script>
//获取最近7天日期
console.log(getDay(0));//当天日期
console.log(getDay(-7));//7天前日期
//获取最近3天日期
console.log(getDay(0));//当天日期
console.log(getDay(-3));//3天前日期
function getDay(day){
    var today = new Date();
    var targetday_milliseconds=today.getTime() + 1000*60*60*24*day;
    today.setTime(targetday_milliseconds); //注意，这行是关键代码
    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){
