javascript - 将时间插件更改为 24 小时

Question

目前我使用的是 12 小时格式，这意味着 AM、PM 概念，我想将此时间选择器更改为 24 小时并删除 AM、PM。

html代码

<div id="time-range">
<p>Time Range: <span class="slider-time">9:00 AM</span> - <span class="slider-time2">5:00 PM</span>

</p>
<div class="sliders_step1">
    <div id="slider-range"></div>
</div>

CSS代码

什么变化可以让这个时间选择器变成24小时

Answer 1

我认为您需要查看任何操作 Hours > 12 的部分。如果您想要 24 小时制，则无需执行此操作。我非常有信心您可以丢弃下面的两个 block 。

if (hours1 >= 12) {
     if (hours1 == 12) {
         hours1 = hours1;
         minutes1 = minutes1 + " PM";
     } else {
         hours1 = hours1 - 12;
         minutes1 = minutes1 + " PM";
     }
 } else {
     hours1 = hours1;
     minutes1 = minutes1 + " AM";
 }
 if (hours1 == 0) {
        hours1 = 12;
        minutes1 = minutes1;
 }

if (hours2 >= 12) {
        if (hours2 == 12) {
            hours2 = hours2;
            minutes2 = minutes2 + " PM";
        } else if (hours2 == 24) {
            hours2 = 11;
            minutes2 = "59 PM";
        } else {
            hours2 = hours2 - 12;
            minutes2 = minutes2 + " PM";
        }
    } else {
        hours2 = hours2;
        minutes2 = minutes2 + " AM";
    }
