将st，nd，rd和th（普通）后缀添加到数字

Question

我想根据当前日期动态生成文本字符串。因此，例如，如果是第一天，那么我希望我的代码生成=“ Its 1 * st * ”。

总共有12天，因此我执行了以下操作：

1. 我设置了一个for循环，该循环循环了12天。

2. 在我的html中，我为我的元素指定了一个唯一的ID作为目标，请参见下文：

   <h1 id="dynamicTitle" class="CustomFont leftHeading shadow">On The <span></span> <em>of rest of generic text</em></h1>
   

3. 然后，在我的for循环中，我有以下代码：

   $("#dynamicTitle span").html(i);
   

   var day = i;
   if (day == 1) {
   day = i + “st”;
   } else if (day == 2) {
   day = i + “nd”
   } else if (day == 3) {
   day = i + “rd”
   }
   
   

更新

这是请求的整个for循环：

$(document).ready(function () {
    for (i = 1; i <= 12; i++) {
        var classy = "";
        if (daysTilDate(i + 19) > 0) {
            classy = "future";
            $("#Day" + i).addClass(classy);
            $("#mainHeading").html("");
            $("#title").html("");
            $("#description").html("");
        } else if (daysTilDate(i + 19) < 0) {
            classy = "past";
            $("#Day" + i).addClass(classy);
            $("#title").html("");
            $("#description").html("");
            $("#mainHeading").html("");
            $(".cta").css('display', 'none');
            $("#Day" + i + " .prizeLink").attr("href", "" + i + ".html");
        } else {
            classy = "current";
            $("#Day" + i).addClass(classy);
            $("#title").html(headings[i - 1]);
            $("#description").html(descriptions[i - 1]);
            $(".cta").css('display', 'block');
            $("#dynamicImage").attr("src", ".." + i + ".jpg");
            $("#mainHeading").html("");
            $(".claimPrize").attr("href", "" + i + ".html");
            $("#dynamicTitle span").html(i);
            var day = i;
            if (day == 1) {
                day = i + "st";
            } else if (day == 2) {
                day = i + "nd"
            } else if (day == 3) {
                day = i + "rd"
            } else if (day) {
            }
        }
    }

Answer 1

该规则如下：

• st与以1结尾的数字（例如1st，首先发音）一起使用
• nd用于以2结尾的数字（例如，第92个，发音为90秒）
• rd与以3结尾的数字一起使用（例如33rd，发音为三十三）
• 作为上述规则的例外，所有以11、12或13结尾的“青少年”数字都使用-th（例如，11，发音为11、112，发音为100 [和]第十二）
• th用于所有其他数字（例如，第9个，发音为第9个）。
  
  

以下JavaScript代码（于14年6月重写）完成了此任务：

function ordinal_suffix_of(i) {
    var j = i % 10,
        k = i % 100;
    if (j == 1 && k != 11) {
        return i + "st";
    }
    if (j == 2 && k != 12) {
        return i + "nd";
    }
    if (j == 3 && k != 13) {
        return i + "rd";
    }
    return i + "th";
}

0-115之间的数字的示例输出：
