JavaScript中的日期轉換幫助

Question

我有一個格式爲MM/DD/YYYY的字符串。

有人能告訴我如何將其轉換爲：2011年1月1日？

Answer 1

var str = "01/01/2011", 
date = new Date(str), 
months = ["January", "February", "March", "April", "May", "June", 
      "July", "August", "September", "October", "November", "December"], 
converted = months[date.getMonth()] + " " + 
      date.getDate() + ", " + date.getFullYear(); 

See it in action。

Answer 2

如果你還沒有，看看date.js -

http://www.datejs.com/

它的任何日期相關的功能是偉大的，並有噸的例子在他們的網站做的一切你能想象。

更新：好有些人懷疑我瘋狂的skillz編碼:)

<script src="http://www.datejs.com/build/date.js" type="text/javascript"></script> 

<script language="Javascript"> 
    var d = Date.parse('03/08/1980'); 
    window.alert(d.toString('MMMM d, yyyy')); 
</script> 

Answer 3

var str = "1/1/2011"; 

var monthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];  
var parts = str.split("/"); 
var formatted = monthNames[parseInt(parts[0], 10)-1] + " " + parts[1] + ", " + parts[2]; 

Answer 4

我希望這有助於

var dat = new Date("01/01/2011"); 
var monthNames = [ "January", "February", "March", "April", "May", "June","July", "August", "September", "October", "November", "December" ]; 
var stringDate = monthNames[dat.getMonth()] + ", " + dat.getDate() + ", " + dat.getFullYear(); 

Answer 5

我寫了一個最新的圖書館類似DateJS，只有它的體積更小，速度更快，而且不會修改Date.prototype。它處理解析，操作和格式化，包括timeago。

我看到你只需要英語，但是在underscore.date中支持i18n。

隨着underscore.date，這是你將如何解決你的問題。

_date('01/01/2011', 'MM/DD/YYYY').format('MMMM D, YYYY');
