HTML href 变量值

Question

更新： example of code at W3school tryit editor

在我的网页中，我有 20 篇文章的提要，每篇文章下方都有一个社交媒体共享面板，用于分享每篇文章，代码如下：

<a href="http://www.facebook.com/sharer.php?u=HTTPURLTOSHARE">
  <i class="fab fa-facebook"></i>
</a>

所以基本上我对每个社交媒体服务（比如说 10、FB、TW、IG 等）以及每篇文章的全部链接都有几个这样的链接。
我的问题是：有没有办法编写包含所有共享服务链接的 SHARING DIV 每次单击共享按钮时，只需将其 URL (HTTPURLTOSHARE) 分配给社交媒体共享按钮，？
我知道这可能是服务器端，但我不熟悉前端开发。

Answer 1

这不是小事

1. 我做了一个模板
2. 我为弹出链接提供了带有文章 URL 的数据属性
3. 我在每个链接后插入模板内容

window.addEventListener("load",function() {
  [...document.querySelectorAll("a[data-url]")]
    .forEach((lnk,i) => {
      const url = lnk.dataset.url;
      const pop = document.getElementById("sharer").content.cloneNode(true)
      pop.querySelector('.overlay').setAttribute("id",lnk.hash.slice(1)); 
      [...pop.querySelectorAll(".social-square a")].forEach(lnk => lnk.href = lnk.href.replace("SHARE",url))
     lnk.after(pop)
    })
})

<!-- FIRST ARCITLE -->
<h1>We must stop calling Trump’s enablers ‘conservative.’ They are the radical right.</h1>
<p>You hear the word “radical” a lot these days. It’s usually aimed like a lethal weapon at Democratic office-seekers, especially those who want to unseat a Republican incumbent. Sen. Kelly Loeffler, the Georgia Republican, rarely utters her challenger’s name without branding him as “radical liberal Raphael Warnock.”</p>

<!-- SECOND ARTICLE -->
<h1>An Insurgency From Inside the Oval Office</h1>
<p>President Trump’s effort to overturn the election he lost has gone beyond mere venting of grievances at the risk of damaging the very American democracy he is charged with defending.</p>

Answer 2

我认为您将需要（http 调用）到社交信息源以获取文章详细信息（包括链接），然后在获得数据后，您可以合并并呈现页面中的链接。
