JavaScript中的日期转换帮助

Question

我有一个格式为MM/DD/YYYY的字符串。

有人能告诉我如何将其转换为：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

如果你还没有，看看date.js -

http://www.datejs.com/

它的任何日期相关的功能是伟大的，并有吨的例子在他们的网站做的一切你能想象。

更新：好有些人怀疑我疯狂的skillz编码:)

<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

我希望这有助于

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

我写了一个最新的图书馆类似DateJS，只有它的体积更小，速度更快，而且不会修改Date.prototype。它处理解析，操作和格式化，包括timeago。

我看到你只需要英语，但是在underscore.date中支持i18n。

随着underscore.date，这是你将如何解决你的问题。

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