我的网站目前正在建设中，所以我试图在标题链接上添加一点点弹出“即将推出”或类似的东西。你点击它，它就会在链接附近弹出。
这是我正在关注的教程，但无法使用我自己的代码。在这一点上，生病了。
https://www.w3schools.com/howto/howto_js_popup.asp
我觉得我需要做的就是为每个链接添加一个特定的类，只要添加了这个类，或者类似的东西在我看来是最好的。
所以想要把它添加到关于我们，我们的工作和服务按钮。

我为您构建了一个非常简单的示例，我将在此处为您提供代码。
首先，它在行动中：
var selector = document.getElementById('showHide');
selector.onclick = function(){
var show = document.getElementById('hidden');
show.style.display = "block"
};<ul class="nav">
<div class="new">
<li id="showHide"><a href="/">HOME</a></li>
<li id='hidden' style='display: none;'>Hello</li>
<li><a href="/aboutus/">ABOUT US</a></li>
<li><a href="/ourwork/">OUR WORK</a></li>
<li><a href="/services/">SERVICES</a></li>
</div>
</ul>
这将是您的导航栏。如你所见，我做了一些改变。我给你的主页按钮一个id，以便我们以后可以调用它。我还添加了一个新的<li>标记，该标记在网站上隐藏了＆＃34; display：none＆＃34;。
<ul class="nav">
<div class="new">
<li id="showHide"><a href="/" >HOME</a></li>
<li id='hidden' style='display: none;'>Hello</li>
<li><a href="/aboutus/">ABOUT US</a></li>
<li><a href="/ourwork/">OUR WORK</a></li>
<li><a href="/services/">SERVICES</a></li>
</div>
</ul>
这是神奇的
var selector = document.getElementById('showHide');
selector.onclick = function(){
var show = document.getElementById('hidden');
show.style.display = "block"
};
在顶部我们创建一个选择器变量来告诉它我们想要定位的内容，对我们来说这将是Home按钮。
下面我们编写一个在单击选择器时触发的函数。当它被触发时，我们定义我们想要改变的东西（在这种情况下，这将是id为＆＃34的元素;隐藏＆＃34;）。之后，我们只需编辑它的显示属性即可显示。
