將json時間戳轉換爲javascript中的正常日期和時間

Question

我有一個Json時間戳，我想使用javascript將其轉換爲簡單的日期時間格式。

我需要以下列格式的日期和時間：DD-MM-YYYY小時：mn個

這裏是從i希望提取時間戳的示例JSON日期： 「時間戳」：1326439500

Answer 1

日期以自紀元以​​來的毫秒數返回。下面的代碼創建一個JS日期對象：

var d = new Date(1245398693390); 
var formattedDate = d.getDate() + "-" + (d.getMonth() + 1) + "-" + d.getFullYear(); 
var hours = (d.getHours() < 10) ? "0" + d.getHours() : d.getHours(); 
var minutes = (d.getMinutes() < 10) ? "0" + d.getMinutes() : d.getMinutes(); 
var formattedTime = hours + ":" + minutes; 

formattedDate = formattedDate + " " + formattedTime; 

這裏的a working fiddle。

Answer 2

<script> 
var timestamp=1326439320; 
var date=new Date(timestamp); 
var hours = date.getHours(); // minutes part from the timestamp 
var minutes = date.getMinutes(); // seconds part from the timestamp 
var seconds = date.getSeconds(); // will display time in 10:30:23 format 
var formattedTime = hours + ':' + minutes + ':' + seconds; 
alert(formattedTime); 
</script>

擴展Date的原型，包括像這樣的格式函數（或者尋找或創造你自己的）：

Date.prototype.format = function (formatString) { 
    // Returns a formatted date string 
    var month = this.getMonth() + 1, 
     day = this.getDate(), 
     year = this.getFullYear(), 
     hours24 = this.getHours(), 
     hours = (hours24 === 0 ? 12 : hours24 > 12 ? hours24 - 12 : hours24), 
     meridiem = hours24 >= 12 ? "PM" : "AM", 
     minutes = this.getMinutes(), 
     seconds = this.getSeconds(); 

    return formatString.replace(/(MM)/g, month.padLeft(2, '0')) 
     .replace(/(M)/g, month) 
     .replace(/(dd)/g, day.padLeft(2, '0')) 
     .replace(/(d)/g, day) 
     .replace(/(yyyy)/ig, year) 
     .replace(/(yy)/ig, year.toString().substring(2, 4)) 
     .replace(/(hh)/g, hours.padLeft(2, '0')) 
     .replace(/(h)/g, hours) 
     .replace(/(HH)/g, hours24.padLeft(2, '0')) 
     .replace(/(H)/g, hours24) 
     .replace(/(mm)/g, minutes.padLeft(2, '0')) 
     .replace(/(m)/g, minutes) 
     .replace(/(ss)/g, seconds.padLeft(2, '0')) 
     .replace(/(s)/g, seconds) 
     .replace(/(tt)/g, meridiem.toLowerCase()) 
     .replace(/(TT)/g, meridiem); 
}; 

然後，時間戳轉換成所需的格式，dd-mm-yyyy hr:mn（如前所述您的評論），你會做以下幾點：

var dateString = new Date(timestamp).format("dd-MM-yyyy hh:mm"); 

[編輯]這裏是伴隨墊功能：

Number.prototype.padLeft = function (width, padChar) { 
    // Returns a padded string 
    padChar = padChar || ' '; 
    var value = this.toString(); 
    while (value.length < width) { 
     value = padChar + value; 
    } 
    return value; 
};
