如何解决我的轮播无法正常工作...即使我单击下一个或上一个

很抱歉，链接的大小。...Stackoverflow不允许链接缩短器... 之前它工作得很好。但是在提交时，当我检查站点的整个输出时，我注意到它根本不起作用... 它不会改变它的上..它用来做更早... 当我单击下一个或上一个按钮时，看起来就像是'href =“＃”'，它什么都不做...

这是代码- HTML

解决方法

我对您的代码做了一些更改。

已解决的错误是carousel-indicators中<li>内部的以下错误首先被错误地关闭，因此，您必须将其更改为

<li class='active' data-slide-to='0' data-target='#myCarousel' />
<li data-slide-to='1' data-target='#myCarousel' />
<li data-slide-to='2' data-target='#myCarousel' />

到

   <li class='active' data-slide-to='0' data-target='#myCarousel'></li>
   <li data-slide-to='1' data-target='#myCarousel'></li>
   <li data-slide-to='2' data-target='#myCarousel'></li>

我注意到您犯的第二个错误是在carousel-inner内容中 您应该使用类carousel-item而不是item

第三个错误是a标签的类名错误，并且您没有正确关闭span。

<!-- Left and right controls -->
<a class='left carousel-control' data-slide='prev' href='#myCarousel'>
  <span class='glyphicon glyphicon-chevron-left'/>
  <span class='sr-only'>Previous</span>
</a>
<a class='right carousel-control' data-slide='next' href='#myCarousel'>
  <span class='glyphicon glyphicon-chevron-right'/>
  <span class='sr-only'>Next</span>
</a>

a标签类名称应从此更改

  <a class='right carousel-control' data-slide='next' href='#myCarousel'>
  <a class='left carousel-control' data-slide='prev' href='#myCarousel'>

对此

  <a class='carousel-control-prev' data-slide='prev' href='#myCarousel'>
  <a class='carousel-control-next' data-slide='next' href='#myCarousel'>

您可能没有关闭跨度。

您的跨度：

  <span class='glyphicon glyphicon-chevron-left'/>
  <span class='glyphicon glyphicon-chevron-right'/>

它们应该像这样关闭

 <span class='glyphicon glyphicon-chevron-left'></span>
  <span class='glyphicon glyphicon-chevron-right'><span>

我还注意到您正在尝试添加自定义图标。您可以通过替换

  <span class='glyphicon glyphicon-chevron-right'><span>

作者（图标引导程序使用）

<span class="carousel-control-next-icon" aria-hidden="true"></span>

或（来自fontawesome的自定义图标）

<span> <i class="fas fa-arrow-circle-left" aria-hidden="true"></i></span>

如果要使用自定义图标，请不要忘记在fontawesome CDN中添加head。

将所有修复程序应用到此处后，这是您的代码。
