javascript时间戳和日期字符串相互转换

// 获取当前时间戳(以s为单位)
var timestamp = Date.parse(new Date());
timestamp = timestamp / 1000;
//当前时间戳为：1403149534
console.log("当前时间戳为：" + timestamp);

// 获取某个时间格式的时间戳
var stringTime = "2014-07-10 10:21:12";
var timestamp2 = Date.parse(new Date(stringTime));
timestamp2 = timestamp2 / 1000;
//2014-07-10 10:21:12的时间戳为：1404958872 
console.log(stringTime + "的时间戳为：" + timestamp2);

// 将当前时间换成时间格式字符串
var timestamp3 = 1403058804;
var newDate = new Date();
newDate.setTime(timestamp3 * 1000);
// Wed Jun 18 2014 
console.log(newDate.toDateString());
// Wed, 18 Jun 2014 02:33:24 GMT 
console.log(newDate.toGMTString());
// 2014-06-18T02:33:24.000Z
console.log(newDate.toISOString());
// 2014-06-18T02:33:24.000Z 
console.log(newDate.toJSON());
// 2014年6月18日 
console.log(newDate.toLocaleDateString());
// 2014年6月18日 上午10:33:24 
console.log(newDate.toLocaleString());
// 上午10:33:24 
console.log(newDate.toLocaleTimeString());
// Wed Jun 18 2014 10:33:24 GMT+0800 (中国标准时间)
console.log(newDate.toString());
// 10:33:24 GMT+0800 (中国标准时间) 
console.log(newDate.toTimeString());
// Wed, 18 Jun 2014 02:33:24 GMT
console.log(newDate.toUTCString());

Date.prototype.format = function(format) {
       var date = {
              "M+": this.getMonth() + 1,
              "d+": this.getDate(),
              "h+": this.getHours(),
              "m+": this.getMinutes(),
              "s+": this.getSeconds(),
              "q+": Math.floor((this.getMonth() + 3) / 3),
              "S+": this.getMilliseconds()
       };
       if (/(y+)/i.test(format)) {
              format = format.replace(RegExp.$1, (this.getFullYear() + '').substr(4 - RegExp.$1.length));
       }
       for (var k in date) {
              if (new RegExp("(" + k + ")").test(format)) {
                     format = format.replace(RegExp.$1, RegExp.$1.length == 1
                            ? date[k] : ("00" + date[k]).substr(("" + date[k]).length));
              }
       }
       return format;
}
console.log(newDate.format('yyyy-MM-dd h:m:s'));

</script>

1、当前时间换时间戳

var timestamp = parseInt(new Date().getTime()/1000);    // 当前时间戳
document.write(timestamp);

 

2、当前时间换日期字符串

var now = new Date();
var yy = now.getFullYear();      //年
var mm = now.getMonth() + 1;     //月
var dd = now.getDate();          //日
var hh = now.getHours();         //时
var ii = now.getMinutes();       //分
var ss = now.getSeconds();       //秒
var clock = yy + "-";
if(mm < 10) clock += "0";
clock += mm + "-";
if(dd < 10) clock += "0";
clock += dd + " ";
if(hh < 10) clock += "0";
clock += hh + ":";
if (ii < 10) clock += ‘0‘; 
clock += ii + ":";
if (ss < 10) clock += ‘0‘; 
clock += ss;
document.write(clock);     //获取当前日期

 

3、日期字符串转时间戳

var date = ‘2015-03-05 17:59:00.0‘;
date = date.substring(0,19);    
date = date.replace(/-/g,‘/‘); 
var timestamp = new Date(date).getTime();
document.write(timestamp);

 

4、时间戳转日期字符串

var timestamp = ‘1425553097‘;
var d = new Date(timestamp * 1000);    //根据时间戳生成的时间对象
var date = (d.getFullYear()) + "-" + 
           (d.getMonth() + 1) + "-" +
           (d.getDate()) + " " + 
           (d.getHours()) + ":" + 
           (d.getMinutes()) + ":" + 
           (d.getSeconds());
document.write(date);

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

结果是
2010年12月23日 10:53
第二种

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

如果你想得到这样格式的怎么办呢？
2010-10-20 10:00:00
看下面代码吧

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

也可以这样写的

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)); 

好了问题解决
需要注意的是
不要把字符串中的Date(这样的字符也传进去，要先处理一下，这样很方便 就能处理的
可以使用replace方法
如下：

replace("/Date(","").replace(")/","");
