我在评论 div 内的 HTML 标签有问题，当我插入 <p>something</p> 时，更多文本链接没有显示。标签。它适用于纯文本。我想插入富文本，但不起作用。

这是因为你正在采取var content = $(this).html(); 。该html有一个<p>当您使用 substr 时，您最终会得到格式错误的 html，没有结束标记(例如 <p>Some Text )。不同的浏览器对格式错误的 html 的处理方式不同。您的morelink链接被放在 <p> 之外并切换最终隐藏它。使用var content = $(this).text();相反，或者找到一个可以更好地处理这个问题的插件。
