javascript日期时间格式化

Beispiel 1:

<!DOCTYPE html>
<html>
<head>
 <meta charset="UTF-8">
 <title>TT</title>
 <script src="jquery.js"></script>
</head>
<body>
<p style="line-height: 50%;"><span></span></p>
<input type="button" value="轻轻" onclick="syncTime()">
<script>
  function syncTime(){
    var mydate = new Date();
    var week;
    switch (mydate.getDay()){
    case 1: week="星期一"; break;
    case 2: week="星期二"; break;
    case 3: week="星期三"; break;
    case 4: week="星期四"; break;
    case 5: week="星期五"; break;
    case 6: week="星期六"; break;
    default: week="星期天";
    }
    var str = "" + mydate.getFullYear() + " 年 " + (mydate.getMonth() + 1) + " 月 " + mydate.getDate() + " 日 " + week;
    $('.todaytime')[0].innerHTML = str;
    str = '"savesynctime" : "' + str + '"'
    return str;
  }
  console.log(syncTime());
</script>
</body>
</html>

Beispiel 2:

<script type="text/javascript">
    var date = new Date();
 
    document.writeln(date);
    //Thu Jan 08 2015 01:25:53 GMT+0800 (中国标准时间)
    document.writeln(Date.parse());
    //NaN
    document.writeln(Date.parse('6/10/2014'));
    //1402329600000 毫秒数
    document.writeln(Date.parse('Thu Jan 08 2015 01:25:53'));
    //1420651553000 毫秒数
    document.writeln(Date.UTC());
    //NaN
 
    //日期格式化方法
    document.writeln('<br/>');
    document.writeln(date.toDateString());
    //Thu Jan 08 2015
    document.writeln('<br/>')
    document.writeln(date.toTimeString());
    //01:39:08 GMT+0800 (中国标准时间)
    document.writeln('<br/>')
    document.writeln(date.toLocaleDateString());
    //2015年1月8日
    document.writeln('<br/>')
    document.writeln(date.toLocaleTimeString());
    //上午1:39:08
    document.writeln('<br/>')
    document.writeln(date.toUTCString());
    //Wed, 07 Jan 2015 17:39:08 GMT
 
    //一些set，get方法
 
 
  </script>

Beispiel 3:

Date.prototype.Format = function(formatStr) {
  var str = formatStr;
  var Week = ['日', '一', '二', '三', '四', '五', '六'];
  str = str.replace(/yyyy|YYYY/, this.getFullYear());
  str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 &#63; (this.getYear() % 100).toString() : '0' + (this.getYear() % 100));
  str = str.replace(/MM/, (this.getMonth() + 1) > 9 &#63; (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1));
  str = str.replace(/M/g, (this.getMonth() + 1));
  str = str.replace(/w|W/g, Week[this.getDay()]);
  str = str.replace(/dd|DD/, this.getDate() > 9 &#63; this.getDate().toString() : '0' + this.getDate());
  str = str.replace(/d|D/g, this.getDate());
  str = str.replace(/hh|HH/, this.getHours() > 9 &#63; this.getHours().toString() : '0' + this.getHours());
  str = str.replace(/h|H/g, this.getHours());
  str = str.replace(/mm/, this.getMinutes() > 9 &#63; this.getMinutes().toString() : '0' + this.getMinutes());
  str = str.replace(/m/g, this.getMinutes());
  str = str.replace(/ss|SS/, this.getSeconds() > 9 &#63; this.getSeconds().toString() : '0' + this.getSeconds());
  str = str.replace(/s|S/g, this.getSeconds());
  return str
}

Beispiel 5: Zeitpersonalisierte Ausgabefunktion

/*
1、< 60s, 显示为“刚刚”
2、>= 1min && < 60 min, 显示与当前时间差“XX分钟前”
3、>= 60min && < 1day, 显示与当前时间差“今天 XX:XX”
4、>= 1day && < 1year, 显示日期“XX月XX日 XX:XX”
5、>= 1year, 显示具体日期“XXXX年XX月XX日 XX:XX”
