Question

我正在尝试在laravel中创建一个动态轮播，但是我只能看到一张图像。我一直在寻找解决方案，但是我仍然陷入困境

我已尝试通过此解决方案Dynamic carousel in PHP Laravel only shows one image更改代码，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>

Answer 1

其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类。您只需要对单个图像进行激活，就可以使用类似这样的php解决方法对单个图像进行激活。

<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>

您还忘记了关闭<div class="carousel-inner"></div>标签。

Answer 2

在EA - Education - Higher Ed Administration部分，

jquery脚本应首先编写，并以引导程序结尾。如果代码正确并且较早显示单个图像，则应该可以正常工作。
