如何获得星期几和一年中的一个月？ [英] How to get the day of week and the month of the year?

问题描述

我不太了解Javascript，而我发现的其他问题与日期操作有关，不仅仅是获取我需要的信息。

I don't know much about Javascript, and the other questions I found are related to operations on dates, not only getting the information as I need it.

我希望得到以下格式的日期：

I wish to get the date as below-formatted:

打印2011年1月27日星期四17:42:21

Printed on Thursday, 27 January 2011 at 17:42:21

到目前为止，我得到以下内容：

So far, I got the following:

var now = new Date();
var h = now.getHours();
var m = now.getMinutes();
var s = now.getSeconds();

h = checkTime(h);
m = checkTime(m);
s = checkTime(s);

var prnDt = "Printed on Thursday, " + now.getDate() + " January " + now.getFullYear() + " at " + h + ":" + m + ":" s;

我现在需要知道如何获得星期几和月份（他们的名字）

I now need to know how to get the day of week and the month of year (their names).

有没有一个简单的方法来做，或者我会考虑使用数组，我将使用 now.getMonth将其简单地索引到正确的值（）和 now.getDay（）？

Is there a simple way to make it, or shall I consider using arrays where I would simply index to the right value using now.getMonth() and now.getDay()?

推荐答案

是的，你需要数组。

var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

var day = days[ now.getDay() ];
var month = months[ now.getMonth() ];

或者您可以使用 date.js 库。

编辑：

如果要经常使用这些，可能需要扩展 Date.prototype / p>

If you're going to use these frequently, you may want to extend Date.prototype for accessibility.

(function() {
    var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];

    var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];

    Date.prototype.getMonthName = function() {
        return months[ this.getMonth() ];
    };
    Date.prototype.getDayName = function() {
        return days[ this.getDay() ];
    };
})();

var now = new Date();

var day = now.getDayName();
var month = now.getMonthName();
