使用相同的模态制作不同的链接，每个链接显示不同的轮播答案

【问题标题】：Make different links with same modal displays different carousels each one使用相同的模态制作不同的链接，每个链接显示不同的轮播
【发布时间】：2021-01-25 08:27:22
【问题描述】：

我正在开发一个有多个链接的网站。单击时的每个链接都显示具有不同轮播的相同模式。我试图将 id 传递给链接的数据目标，但是当打开模式时，它会播放两个轮播而不是仅选定的轮播。我正在尝试找出问题所在，但我不知道，您有什么建议吗？谢谢。

【解决方案1】：

您可以使用 JavaScript 动态更改您的 <div>s 的可见性。

首先，将 onclick 函数添加到所有四个 <a> 标签：

<a href="" onclick="showContent(this)" data-target="#carouselExample1" data-slide-to="0">

当你点击它时，这将调用一个函数。

然后，将以下函数添加到您的 <script> ：

function showContent(object){
  if (object.dataset.target == '#carouselExample1' ){
        document.getElementById("carouselExample2").style.display = "none";
        document.getElementById("carouselExample1").style.display = "block";
    }
    else{
        document.getElementById("carouselExample1").style.display = "none";
        document.getElementById("carouselExample2").style.display = "block";
    }
}

上面的函数会检查你点击的链接的data-target，并根据它显示/隐藏div。

我建议检查 JavaScript HTML DOM 事件以获取更多信息。
