我试图让模式中的轮播在用户选择的图像上打开。我已经尝试过data-slide-to="##"，但没有看到。我将在下面发布代码。我将删除重复的代码。<!DOCTYPE html><html><head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <title>Name LTD - Gallery</title> <!-- Bootstrap core CSS --> <link href="vendor/bootstrap/css/bootstrap.min.css" rel="stylesheet"> <!-- Custom styles for this template --> <link href="css/shop-homepage.css" rel="stylesheet"> <link href="css/carousel.css" rel="stylesheet" id="bootstrap-css"> <script src="//code.jquery.com/jquery-1.11.1.min.js"></script> <script src="//netdna.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script></head><body> <!-- Navigation --> <nav class="navbar navbar-expand-lg navbar-dark bg-secondary fixed-top"> <div class="container"> <a class="navbar-brand" href="index.php">Name</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarResponsive"> <ul class="navbar-nav ml-auto"> <li class="nav-item"> <a class="nav-link" href="index.php">Home</a> </li> <li class="nav-item"> <a class="nav-link" href="#">About</a> </li> <li class="nav-item active"> <a class="nav-link" href="#">Gallery <span class="sr-only">(current)</span> </a> </li> <li class="nav-item"> <a class="nav-link" href="contact.php">Contact</a> </li> </ul> </div> </div> </nav>因此，当前当用户选择图像 1 时，图像 1 显示在轮播上，但如果选择图像 2，则图像 1 仍然首先显示，依此类推。所以我想要的是用户能够选择图像 3 和图像 3在轮播中被选择，这样他们就不必滚动轮播才能到达它。

您还应该通过执行data-target="#carousel-example-generic"将图像指向滑块，因为您将标签仅指向模态，这就是它不更新滑块的原因，
所以下面的代码可能对你有帮助
<div class="row text-center text-lg-left">
<div class="col-lg-3 col-md-4 col-6">
<a href="#" class="d-block mb-4 h-100" data-toggle="modal" data-target=".imgGal">
<img src="img/img14.png" class="img-fluid img-thumbnail" data-target="#carousel-example-generic" data-slide-to="0">
</a>
</div>
<div class="col-lg-3 col-md-4 col-6">
<a href="#" class="d-block mb-4 h-100" data-toggle="modal" data-target=".imgGal">
<img src="img/img15.png" class="img-fluid img-thumbnail" data-target="#carousel-example-generic" data-slide-to="1">
</a>
</div>
<div class="col-lg-3 col-md-4 col-6">
<a href="#" class="d-block mb-4 h-100" data-toggle="modal" data-target=".imgGal">
<img src="img/img9.png" class="img-fluid img-thumbnail" data-target="#carousel-example-generic" data-slide-to="2">
</a>
</div>
<div class="col-lg-3 col-md-4 col-6">
