以下是我目前的代码。目前注册和加入链接位于左上角。我希望这些位于下拉菜单中。所以在左上角我想要一个下拉菜单，当我将鼠标悬停在菜单上时，这两个链接会出现在那里，当我单击它们时，相同的弹出窗口会出现在屏幕中间。

最佳答案
这应该很容易做到。
用这个替换 header-links div 中的代码。
HTML:
<ul>
<li><a href="#">Dropdown</a>
<ul>
<li><a href="#" onclick="signin()">Sign In</a></li>
<li><a href="#" onclick="join()">Join</a></li>
</ul>
</li>
</ul>
并将其添加到您的 css 类中
CSS:
ul ul {
display: none;
}
ul li:hover > ul {
display: block;
}
我还建议您删除 .header-links 类中的负边距，并将 float:left 添加到您的 #header-img-wrap.
希望对您有所帮助。
关于javascript - 我想创建一个弹出框。应该使用下拉菜单访问，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28272587/
