添加日期后缀[重复]

Question

我有以下 Javascript 来显示页面上的日期，但是我想在每个日期编号后添加“th”、“st”和“rd”后缀（即“6th”）。

有没有办法用我目前拥有的以下代码来做到这一点？

    <script language="Javascript">
<!-- 

// Array of day names
var dayNames = new Array("You're working today? It's Sunday","Hello, it's Monday","Hello, it's Tuesday","Hello, it's Wednesday",
    "Hello, it's Thursday","Hello, it's Friday","You're working today? It's Saturday");

// Array of month Names
var monthNames = new Array(
"January","February","March","April","May","June","July",
"August","September","October","November","December");

var now = new Date();
document.write (dayNames[now.getDay()] + ", " + 
now.getDate() + " " + 
monthNames[now.getMonth()] + " " + 
now.getFullYear() + ".");
// -->
</script>

提前致谢

Answer 1

如果您不想使用库，还有其他解决方案。在 StackOverflow 上进行快速搜索让我找到了这个answer。您需要将这些函数之一合并到您的代码中，获取来自now.getDate() 的值。

Answer 2

您正在使用dayNames[now.getDay()] 表明您要搜索的键是now.getDay()，它不是从零开始的。我建议您将周日的值移到数组末尾，并使用dayNames[now.getDay() - 1] 更清楚。
