Laravel 中的动态轮播无法正常工作，仅显示一张图片

Question

我正在尝试在 laravel 中创建动态轮播，但我只看到一张图片。我已经找了好几个小时的解决方案，但还是卡住了

我已尝试通过此解决方案更改我的代码Dynamic carousel in PHP Laravel only shows one image但没有成功

home.blade.php代码

<div id="myCarousel" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0"     class="active">                                                                   </li>
</ol>

<div class="carousel-inner" role="listbox">
@foreach($sliders as $slider)
<div class="carousel-item active">
<img src="{{url('images', $slider->image)}}" class="d-block w-100"  alt="..."> 
</div>
@endforeach

<a class="carousel-control-prev" href="#myCarousel" 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="#myCarousel" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>

</head>
<body>

@include('front.nav')
@yield('content')
@include('front.footer')
</body>
</html>

我们将不胜感激。

Answer 1

它不起作用的问题是因为循环

@foreach($sliders as $slider)
  <div class="carousel-item active">
     <img src="{{url('images', $slider->image)}}" class="d-block w-100"  alt="..."> 
  </div>
@endforeach

正在向所有图像添加 active class。您只需要在单个图像上激活，您可以使用像这样的 php 解决方法在单个图像上设置激活。

<div id="myCarousel" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
        <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    </ol>
    <div class="carousel-inner">
        @foreach($sliders as $key => $slider)
        <div class="carousel-item {{$key == 0 ? 'active' : '' }}">
            <img src="{{url('images', $slider->image)}}" class="d-block w-100"  alt="..."> 
        </div>
        @endforeach
    </div>
    <a class="carousel-control-prev" href="#myCarousel" 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="#myCarousel" role="button" data-slide="next">
        <span class="carousel-control-next-icon" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
    </a>
</div>

你也忘了关闭 <div class="carousel-inner"></div> 标签。

Answer 2

在<head>部分，

jquery脚本应该先写，bootstrap写在后面。如果代码是正确的并且之前显示了单个图像，那么它现在应该可以工作了。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>

Answer 3

<div class="carousel-item {{$loop->iteration == 1 ? 'active' : ''}}">
