1、时间格式化
//昨天的时间
var day1 = new Date();
day1.setTime(day1.getTime()-24*60*60*1000);
var s1 = day1.getFullYear()+"-" + (day1.getMonth()+1) + "-" + day1.getDate();
//今天的时间
var day2 = new Date();
day2.setTime(day2.getTime());
var s2 = day2.getFullYear()+"-" + (day2.getMonth()+1) + "-" + day2.getDate();
//明天的时间
var day3 = new Date();
day3.setTime(day3.getTime()+24*60*60*1000);
var s3 = day3.getFullYear()+"-" + (day3.getMonth()+1) + "-" + day3.getDate();
//拼接时间
function show(){
var str = "" + s1 + "至" + s2;
return str;
}
//赋值doubleDate
$('#dateS').val(show());
2、下面是具体到时分秒的获取方法
function writeCurrentDate() {
var now = new Date();
var year = now.getFullYear(); //得到年份
var month = now.getMonth();//得到月份
var date = now.getDate();//得到日期
var day = now.getDay();//得到周几
var hour = now.getHours();//得到小时
var minu = now.getMinutes();//得到分钟
var sec = now.getSeconds();//得到秒
var MS = now.getMilliseconds();//获取毫秒
var week;
month = month + 1;
if (month < 10) month = "0" + month;
if (date < 10) date = "0" + date;
if (hour < 10) hour = "0" + hour;
if (minu < 10) minu = "0" + minu;
if (sec < 10) sec = "0" + sec;
if (MS < 100)MS = "0" + MS;
var arr_week = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六");
week = arr_week[day];
var time = "";
time = year + "年" + month + "月" + date + "日" + " " + hour + ":" + minu + ":" + sec + " " + week;
//当前日期赋值给当前日期输入框中(jQuery easyUI)
$("#currentDate").html(time);
//设置得到当前日期的函数的执行间隔时间,每1000毫秒刷新一次。
var timer = setTimeout("writeCurrentDate()", 1000);
}
3、2017.6.27更新
今天又发现了一种简单的方法:可以直接对年月日时分秒进行操作,假如今天2017-06-01 那么所得昨天为 2017-05-31
//昨天的时间
var day1 = new Date();
day1.setDate(day1.getDate() - 1);
var s1 = day1.format("yyyy-MM-dd");
//前天的时间
var day2 = new Date();
day2.setDate(day2.getDate() - 2);
var s2 = day2.format("yyyy-MM-dd");
