如何使用鼠标悬停显示弹出窗口来获取 div id？

Question

假设，我有很多 div。现在我想显示单独的弹出窗口，div 明智。我使用了鼠标悬停。它运作良好。但是第一次没有工作。当我第二次移动鼠标时，它起作用了。

这是我的代码：

$(document).ready(function() {
  $(".popper").one('mousemove', function() {
    var messageId = this.id;
    console.log(messageId);
    $("#" + messageId).popover({
      placement: 'bottom',
      container: 'body',
      html: true,
      content: function() {
        return $('.popper-content-' + messageId).html();
      }
    });
  });
});

body {
  padding: 10px 120px;
}

.red {
  color: red;
}

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.1/dist/css/bootstrap.min.css" rel="stylesheet" />

<a class="popper btn btn-outline-warning" id="1" data-bs-trigger="hover" data-bs-toggle="popover">Hover me</a>
<a class="popper btn btn-outline-warning" id="2" data-bs-trigger="hover" data-bs-toggle="popover">Hover me</a>
<a class="popper btn btn-outline-warning" id="3" data-bs-trigger="hover" data-bs-toggle="popover">Hover me</a>
<a class="popper btn btn-outline-warning" id="4" data-bs-trigger="hover" data-bs-toggle="popover">Hover me</a>


<div class="popper-content-1 d-none">My <b class="red">first</b> button popover content goes here.</div>
<div class="popper-content-2 d-none">My <b class="red">second</b> button popover content goes here.</div>
<div class="popper-content-3 d-none">My <b class="red">third</b> popover content goes here.</div>
<div class="popper-content-4 d-none">My <b class="red">fourth</b> popover content goes here.</div>

如何在第一次显示弹出框？

请帮忙。

提前致谢！

您必须先悬停并手动显示 popover()，因为稍后要构建它。

.popover('show');
