jQuery使用$(选择器)预处理多个div

$('.dash').each((i, el) => {
    console.log(el);
    el.prepend('<div class="digit"><div class="top" style="display: none;">0</div><div class="bottom" style="display: block;">0</div></div>');
})

我希望它能创造出

<div class="dash days_dash">
  <div class="digit">
    <div class="top" style="display: none;">0</div>
    <div class="bottom" style="display: block;">0</div>
  </div>
  <div class="digit">
    <div class="top" style="display: none;">0</div>
    <div class="bottom" style="display: block;">0</div>
  </div>
  <div class="digit">
    <div class="top" style="display: none;">0</div>
    <div class="bottom" style="display: block;">0</div>
  </div>
  <h3>Days</h3>
</div>

但它只是简单地将文本显示在视图上。 <div class="digit"><div class="top" style="display: none;">0</div><div class="bottom" style="display: block;">0</div></div>

我在这里做错什么了?
