javascript - JS中如何去除多余的元素内容？

Question

我正在编写下面的 html 代码，即将进行检查。在下面的 class="schedule-wrapper" 代码中有一个属性data-timezone 其值为 "et"。单击按钮时，data-timezone 属性值会发生变化，如下面的屏幕截图所示。单击按钮时(PT、MT、CT、ET、AT、NT)，页面刷新不会发生。

<div class="schedule-wrapper" id="js-schedule" data-timezone="et">         /* The value of data-timezone attribute changes on button click from the Screenshot below */ 

   <!-- List of button start -->
   <div class="schedule-action-bar">
      <div class="schedule-timezone-filter">
         Select your timezone:            
         <ul id="js-timezone-picker">
            <li>
               <button id="js-time-ct" class="" data-timezone="ct">CT</button>
            </li>
            <li>
               <button id="js-time-et" class="" data-timezone="et">ET</button>
            </li>
         </ul>
      </div>
    </div>
    <!-- List of button end -->

    <!-- .schedule-show -->
    <div class="schedule-show">
        <div class="schedule-show-time">
              <time datetime="02:45 24-07-2019" data-timezone="ct">July 24  02:45</time>
               <time datetime="03:45 24-07-2019" data-timezone="et">July 24  03:45</time>           /* When timezone is eastern standard time */
        </div>
    </div>
    <!-- .schedule-show -->
    <div class="schedule-show">
        <div class="schedule-show-time">
              <time datetime="04:00 24-07-2019" data-timezone="ct">July 24  04:00</time>
              <time datetime="05:00 24-07-2019" data-timezone="et">July 24  05:00</time>            /* When timezone is eastern standard time */
        </div>
    </div>
   <!-- .schedule-show -->

</div>

问题陈述:

我想知道我需要添加什么Javascript代码，以便我们可以隐藏(或隐藏/使视觉上不那么突出)当值与上一行含义相同时的日期不在日期与前一行相同的行上显示某一天，以便按日期出现视觉中断。

简而言之，正如上面的屏幕截图中提到的，我不希望该日期用圆圈标记。

I made a fiddle here

// we have to iterate backwards... actually maybe we don't..
$($('.schedule-show').get().reverse()).each(function(i, div){
  let time = $(div).find('[data-timezone="et"]')
  let nextTime = $(div).find('+ .schedule-show [data-timezone="et"]')
  if(nextTime[0]){
    // check if the dates match
    if(nextTime.text().match(/\w+ \d+/)[0] === time.text().match(/\w+ \d+/)[0]){
      // "white out" the dates that match
      nextTime.html(nextTime.text().replace(/(\w+ \d+)/, "<font color=\"white\">$1</font>"))
    }
  }
})
