【问题描述】:
我目前正在尝试构建一个网站,该网站将在同一页面中执行我想要的所有功能,而不是在不同页面中导航。我的页面现在是这样的
当我从侧边栏单击客户端时,我希望加载一个表单来代替我在侧边栏右侧的欢迎用户消息。所有客户的形式都是相同的。是否也可以将我将选择的客户端保存在一个变量中,以便我以后可以使用它来接收来自 mysql 数据库的元素?
有人可以请教我吗? 我的源代码如下:

<script>
/* Loop through all dropdown buttons to toggle between hiding and showing its dropdown content - This allows the user to have multiple dropdowns without any conflict */
var dropdown = document.getElementsByClassName("dropdown-btn");
var i;
for (i = 0; i < dropdown.length; i++) {
dropdown[i].addEventListener("click", function() {
this.classList.toggle("active");
var dropdownContent = this.nextElementSibling;

} else {

}
});

在此致谢

我会给你大致的想法。将带有欢迎消息的整个 html 放在一个 div 中。并将该 div 设置为 .active 类。当您单击列表中的一项时,请执行 $(".active").removeClass("active")。并将 .active 类添加到您的 li 所链接的内容中。默认情况下,这些 div 是 display:none,默认情况下你有一个 .active 。 .active 是 display:block。多田。

这对于 SO 的 QA 格式 IMO 来说太宽泛了...
