jQuery附加到子元素

问题描述

我有一个这样的jQuery。

$.each($(".fc-daygrid-day "),function (key,val) {
  var dateYMD = $(this).attr("data-date");
  console.log(this); 
  $(this).append(`<div class="fc-dailytotal" id='dailytotal-" + dateYMD + "'></div>`);
});

哪个返回这样的信息。（这就是我console.log(this)时得到的）

<td class="fc-daygrid-day fc-day fc-day-thu fc-day-future fc-day-other" data-date="2020-11-05">
  <div class="fc-daygrid-day-frame fc-scrollgrid-sync-inner"> <!-- line 2 -->
    <div class="fc-daygrid-day-top"><a class="fc-daygrid-day-number">5</a></div>
    <div class="fc-daygrid-day-events"></div>
    <div class="fc-daygrid-day-bg"></div>
  </div>
  <div class="fc-dailytotal" id="dailytotal-&quot; + dateYMD + &quot;">0</div> <!-- line 1 -->
</td>

我要在第2行div标签内追加第1行吗？我想要的最终结果如下。谢谢。（我是JQuery的新手）

<td class="fc-daygrid-day fc-day fc-day-thu fc-day-future fc-day-other" data-date="2020-11-05">
  <div class="fc-daygrid-day-frame fc-scrollgrid-sync-inner"> <!-- line 2 -->
    <div class="fc-daygrid-day-top"><a class="fc-daygrid-day-number">5</a></div>
    <div class="fc-dailytotal" id="dailytotal-&quot; + dateYMD + &quot;">0</div> <!-- line 1 -->
    <div class="fc-daygrid-day-events"></div>
    <div class="fc-daygrid-day-bg"></div>
  </div>
</td>
