因此,我試圖將UTC時間轉換爲短格式的客戶端本地時間。我使用下面的代碼:javascript/jquery將utc轉換爲短格式的本地時間

var date = new Date(call.Timestamp); 
date.toLocaleString() 

而且我得到的屏幕上像這樣的輸出:

星期四2012年9月13日14時33分15秒GMT + 1000(澳大利亞東部標準時間)

我想要做的就是我一旦它轉換成日期對象以顯示短格式: DD/MM/YYYY HH:MM:SS或MM/DD/YYYY HH:MM:SS根據在什麼時區。 有沒有一個標準的方式,我可以做到這一點JavaScript的?有誰知道可以爲我做的這個庫包嗎?

我也曾嘗試:

date.toLocaleDateString() + ' ' + date.toLocaleTimeString() 

但日線仍輸出:「週四,2012年9月13日」,而不是

在JavaScript中日期的工作一直是頸部疼痛。我發現迄今爲止最好的圖書館是Sugar.js

Sugar將Date對象擴展爲一些非常強大且具有表現力的日期創建和操作方法。我認爲只有Date.create()會照顧你需要的東西。這是Date構造函數的更好的版本,所以它仍然會返回一個Date對象。它需要兩個選項參數。一個用於locale,一個用於utc。

Here你可以看到方法的細節。

javascript Date沒有格式化日期字符串的任何方法。你必須做你自己使用的方法獲得它的日期,月份,年份,小時等

裁判:https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date#Methods_2

爲如:

var date = new Date(); 
var d = [date.getDate(), date.getMonth()+1, date.getFullYear()]; 
var t = [date.getHours(), date.getMinutes(), date.getSeconds()]; 
var dateStr = d.join("/") + " " + t.join(":"); 

否則,你可以使用任何庫就像一個建議由@ethagnawl支持很多格式選項。

jQuery的日期foramtting僅適用於jQuery UI的日期選擇器,演示它的,你可以在這裏找到http://jqueryui.com/demos/datepicker/date-formats.html

很久以前,我發現這個有用的劇本,我永遠使用它,因爲:
