[DBW]js获取当前时间(昨天、今天、明天)

 1 //昨天的时间
 2 var day1 = new Date();
 3 day1.setTime(day1.getTime()-24*60*60*1000);
 4 var s1 = day1.getFullYear()+"-" + (day1.getMonth()+1) + "-" + day1.getDate();
 5 //今天的时间
 6 var day2 = new Date();
 7 day2.setTime(day2.getTime());
 8 var s2 = day2.getFullYear()+"-" + (day2.getMonth()+1) + "-" + day2.getDate();
 9 //明天的时间
10 var day3 = new Date();
11 day3.setTime(day3.getTime()+24*60*60*1000);
12 var s3 = day3.getFullYear()+"-" + (day3.getMonth()+1) + "-" + day3.getDate();
13 //拼接时间
14 function show(){
15      var str = "" + s1 + "至" + s2;
16      return str;
17 }
18 //赋值doubleDate
19  $(‘#dateS‘).val(show());        

 1 function writeCurrentDate() {
 2         var now = new Date();
 3         var year = now.getFullYear(); //得到年份
 4         var month = now.getMonth();//得到月份
 5         var date = now.getDate();//得到日期
 6         var day = now.getDay();//得到周几
 7         var hour = now.getHours();//得到小时
 8         var minu = now.getMinutes();//得到分钟
 9         var sec = now.getSeconds();//得到秒
10 　　     var MS = now.getMilliseconds();//获取毫秒
11         var week;
12         month = month + 1;
13         if (month < 10) month = "0" + month;

23         //当前日期赋值给当前日期输入框中（jQuery easyUI）
24         $("#currentDate").html(time);
25         //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。
26         var timer = setTimeout("writeCurrentDate()", 1000);
