Javascript以特定格式写入时间

发布于 2024-11-19 16:28:27 字数 582 浏览 2 评论 0原文

我正在使用 Javascript 和 Date.js，并且需要翻译时间的字符串表示形式。

我从这种格式的时间开始：

3:00am
2:30pm 
11:00am

...并且需要将它们放入这种格式：

03:00:00
14:00:00
11:00:00

我正在考虑从 Date.parse() 开始，然后打印出小时、分钟和秒。但想知道是否有更优雅的方法来执行此操作，例如 Date.format("HH:MM:SS")

这样做的好方法是什么？

谢谢！

看来您可以在 Date.js 中使用格式说明符：http://code.google.com/p/datejs/wiki/FormatSpecifiers

Date.parse("3:00am").toString("HH:mm:ss");

I'm using Javascript along with Date.js and need to translate string representations of times.

I'm starting with times in this format:

3:00am
2:30pm 
11:00am

...and need to put them in this format:

03:00:00
14:00:00
11:00:00

I was thinking of starting with Date.parse() and then printing out the hours, minutes, and seconds. But was wondering if there is a more elegant way to do this such as something along the lines of Date.format("HH:MM:SS")

What is a good way to do this?

Thanks!

Edit::::

It looks like you can use the format specifiers with Date.js: http://code.google.com/p/datejs/wiki/FormatSpecifiers

Date.parse("3:00am").toString("HH:mm:ss");

我相信这就是OP正在寻找的答案。 :-)

<html>
  <head>
    <title>Show US Times in 24h form with Date.js</title>
  </head>
  <body>
    <script type="text/javascript" src="date.js"></script>  
    <script>
      var d = Date.parseExact("2:30pm", "h:mmtt");
      document.write(d.toString("HH:mm:ss"));
    </script>
  </body>
</html>
