js 時間戳記轉為日期格式

下面先來看第一種吧

代碼如下	複製代碼
<script>     function getLocalTime(nS) {        return new Date(parseInt(nS) * 1000).toLocaleString().replace(/:d{1,2}$/,' ');     }     alert(getLocalTime(1293072805));     </script>

結果是
2010年12月23日 10:53

第二種

 

代碼如下	複製代碼
<script>     function getLocalTime(nS) {         return new Date(parseInt(nS) * 1000).toLocaleString().substr(0,17)}     alert(getLocalTime(1293072805));     </script>

如果你想得到這樣格式的怎麼辦呢？
2010-10-20 10:00:00
看下面代碼吧

代碼如下	複製代碼
<script>         function getLocalTime(nS) {            return new Date(parseInt(nS) * 1000).toLocaleString().replace(/年|月/g, "-").replace(/日/g, " ");          }         alert(getLocalTime(1177824835));         </script>

也可以這樣寫的

代碼如下

複製代碼

function   formatDate(now)   {                   var   year=now.getYear();                   var   month=now.getMonth()+1;                   var   date=now.getDate();                   var   hour=now.getHours();                   var   minute=now.getMinutes();                   var   second=now.getSeconds();                   return   year+"-"+month+"-"+date+"   "+hour+":"+minute+":"+second;                   }                            var   d=new   Date(1230999938);                   alert(formatDate(d)); 好了問題解決

需要注意的是
不要把字串中的Date(這樣的字元也傳進去，要先處理一下，這樣很方便 就能處理的
可以使用replace方法
如下：

代碼如下	複製代碼
replace("/Date(","").replace(")/","");

完整執行個體

調用方法 能夠很方便的將時間戳記轉換成日期的格式，如：

代碼如下	複製代碼
date('Y-m-d','1350052653');//很方便的將時間戳記轉換成了2012-10-11 date('Y-m-d H:i:s','1350052653');//得到的結果是2012-10-12 22:37:33
