js gets the current time (yesterday, today, tomorrow)

//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());

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); }
