Question

我有一个圣诞节倒计时时钟工作正常，但是，当它显示1小时时，它说1'小时'不是1'小时'

我知道这有点小事，但我希望它是正确的，并显示正确的单词。

有人可以帮忙吗？

守则

<script language="javascript" type="text/javascript">
today = new Date();
  BigDay = new Date("December 25, 2013")
    msPerDay = 24 * 60 * 60 * 1000 ;
      timeLeft = (BigDay.getTime() - today.getTime());
         e_daysLeft = timeLeft / msPerDay;
            daysLeft = Math.floor(e_daysLeft);
               e_hrsLeft = (e_daysLeft - daysLeft)*24;
           hrsLeft = Math.floor(e_hrsLeft);
       minsLeft = Math.floor((e_hrsLeft - hrsLeft)*60);
      document.write( "There's only "+daysLeft+" days, "+hrsLeft+" hours and "+minsLeft+" minutes left until Christmas!");
</script>

非常感谢PBrown

Answer 1

（作为旁注，you probably shouldn't use document.write）。

这是使用JS的ternary operator。

的好地方

var hoursStr = hrsLeft === 1 ? hrsLeft + 'hour' : hrsLeft + 'hours';

Answer 2

today = new Date();
BigDay = new Date("December 25, 2013");
msPerDay = 24 * 60 * 60 * 1000;
timeLeft = (BigDay.getTime() - today.getTime());
e_daysLeft = timeLeft / msPerDay;
daysLeft = Math.floor(e_daysLeft);
e_hrsLeft = (e_daysLeft - daysLeft) * 24;
hrsLeft = Math.floor(e_hrsLeft);
minsLeft = Math.floor((e_hrsLeft - hrsLeft) * 60);
document.write("There's only " + daysLeft + getDayText(daysLeft) + " , " + hrsLeft + getHourText(hrsLeft) + " and " + minsLeft + getMinuteText(minsLeft) + " left until Christmas!");

function getHourText(hour) {
    if (hour > 1) {
        return " hours";
    }

    return " hour";
}

function getMinuteText(min) {
    if (min > 1) {
        return " minutes";
    }

    return " minute";
}

function getDayText(day) {
    if (day > 1) {
        return " days";
    }

    return " day";
}

编辑：上面当然是漫长的做法，绝对不是大多数人的首选方式。您也可以使用三元运算符并执行以下操作：

var str = hours + (hours > 1 ? " hours " : " hour ") + "left!";

Answer 3

function pluralize(num, str){
    if(num > 1){
        return num+' '+str+'s';
    }
    return num+' '+str;
}

使用

var hrsLeft = 20;
pluralize(hrsLeft, 'hour');

返回

20 hours

这是非常基本的，它存在这个功能的更完整版本。

格式化小时 - 1小时，多小时
