【问题描述】：

假设，我有很多 div。现在我想显示单独的弹出框，div 明智。我用鼠标悬停。它运作良好。但第一次不工作。当我第二次移动鼠标时，它正在工作。

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;

<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>

第一次如何显示弹出框？

请帮忙。

提前致谢！

【问题讨论】：

离题：var messageId = this.id; $("#" + messageId) 将与 $(this) 相同（假设您没有重复的 ID）

@Dev 我看到你已经撤销了批准。你有什么问题吗？随意写评论。

@BOZ 对不起。这是我的错误。你的回答对我帮助很大。谢谢。

【参考方案1】：

您必须先悬停并手动显示popover()，因为您稍后会构建它。

.popover('show');

示例 sn-p

$(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();
      
    ).popover('show');
  );
);

body 
  padding: 10px 120px;
