Bootstrap 轮播在 ASP.NET Core 中不起作用

Question

我尝试在我的 ASP NET Core MVC Web 应用程序中创建 bootstrap 轮播。其他 Bootstrap 组件似乎工作正常，轮播不工作。

这是我放入 CSHTML 文件的轮播代码：

<div id="companyPhotosCarousel" class="carousel slide" data-ride="carousel" style="margin-top:-15px">
    <ol class="carousel-indicators">
        <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
        <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
        <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>


    <div class="carousel-inner" role="listbox">

        <div class="item active">
            <img class="img-fluid" src="~/Content/companies/photo_1.jpg" />
        </div>
        <div class="item">
            <img class="img-fluid" src="~/Content/companies/photo_2.jpg"/>
        </div>
        <div class="item">
            <img class="img-fluid" src="~/Content/companies/photo_3.jpg" />
        </div>

    </div>

    <a class="left carousel-control" href="#companyPhotosCarousel" role="button" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#companyPhotosCarousel" role="button" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
    </a>
</div>

Photos are displayed on top of each other

首先，如果您能说出您使用的是哪个 Bootstrap 版本，那将会很有帮助，但我希望这会有所帮助。

同时，尝试检查正在使用的 jQuery 和 bootstrap 版本。以及你排列它们的顺序。

确保 jQuery 出现在 bootstrap 脚本之前。

对于Bootstrap 4 这是一个入门模板。

 <!doctype html>
 <html lang="en">
 <head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

    <title>Hello, world!</title>
  </head>
  <body>
    <h1>Hello, world!</h1>

<!-- Optional JavaScript -->
<!-- jQuery first, then Popper.js, then Bootstrap JS -->
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>

这是轮播模板

<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">

<div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src="..." alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="..." alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="..." alt="Third slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
