轮播指示器不起作用。我不知道为什么

Question

我无法更改带有指示符的轮播图像，它们不起作用。我找不到我做错了什么。没有css或js只是引导。当我单击指示器时，不会发生任何事情，只有活动幻灯片可见。

<link rel="stylesheet" href="inc/css/bootstrap.css">
<link rel="stylesheet" href="inc/css/styles.css">
<!-- Start Img Slider -->
<div id="slide " class="carousel h-100 mw-100 " data-ride="carousel">
<ol class="carousel-indicators ">
<li data-target="slide" data-slide-to="0" class="active"></li>
<li data-target="slide" data-slide-to="1"></li>
<li data-target="slide" data-slide-to="2"></li>
</ol>
<div class="carousel-inner img-fluid" role=listbox>
<!-- slide 1 -->
<div class="carousel-item active " style="background-image: url(images/team1.jpg); background-repeat: no-repeat;">
<div class="carousel-caption">
</div>
</div>
<!-- slide 2 -->
<div class="carousel-item  " style="background-image: url(images/team2.png); background-repeat: no-repeat;">
<div class="carousel-caption">

<div class="carousel-item  " style="background-image: url(images/team3.png); background-repeat: no-repeat;">
<div class="carousel-caption">

更新已解决!!

只是忘记#在数据目标

<ol class="carousel-indicators ">
<li data-target="#slide" data-slide-to="0" class="active"></li>
<li data-target="#slide" data-slide-to="1"></li>
<li data-target="#slide" data-slide-to="2"></li>
</ol>

Answer 1

您需要为指标控件添加以下内容：

<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>

Answer 2

您错过了双引号 ("( 我相信你的问题就是这个

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

替换为此

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