javascript時間戳和日期字符串相互轉換

// 獲取當前時間戳(以s為單位) var timestamp = Date.parse(new Date()); timestamp = timestamp / 1000; //當前時間戳為：1403149534 console.log("當前時間戳為：" + timestamp); // 獲取某個時間格式的時間戳 var stringTime = "2014-07-10 10:21:12"; var timestamp2 = Date.parse(new Date(stringTime)); timestamp2 = timestamp2 / 1000; //2014-07-10 10:21:12的時間戳為：1404958872 console.log(stringTime + "的時間戳為：" + timestamp2); // 將當前時間換成時間格式字符串 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 (中國標准時間) console.log(newDate.toString()); // 10:33:24 GMT+0800 (中國標准時間) 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、當前時間換時間戳

var timestamp = parseInt(new Date().getTime()/1000); // 當前時間戳 document.write(timestamp);

 

2、當前時間換日期字符串

var now = new Date(); var yy = now.getFullYear(); //年 var mm = now.getMonth() + 1; //月 var dd = now.getDate(); //日 var hh = now.getHours(); //時 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); //獲取當前日期

 

3、日期字符串轉時間戳

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、時間戳轉日期字符串

var timestamp = ‘1425553097‘;
var d = new Date(timestamp * 1000);    //根據時間戳生成的時間對象
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> 

 

結果是
2010年12月23日 10:53
第二種

 

<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么辦呢？
2010-10-20 10:00:00
看下面代碼吧

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

也可以這樣寫的

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)); 

好了問題解決
需要注意的是
不要把字符串中的Date(這樣的字符也傳進去，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：

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