所以我通读了this question，但我仍然无法实现代码。我已经将javascript完全复制到我的custom.js文件中，它说我的HTML代码不需要修改。但是，它仍然无法正常工作。我需要改变什么？
HTML文件的相关部分：
<!-- Nav bar -->
<ul class="dropdown-menu" role="menu">
<li><a href="project1.html?slide=0">Project 1</a></li>
<li><a href="project1.html?slide=1">Project 2</a></li>
<li><a href="project1.html?slide=2">Project 3</a></li>
</ul>
<!-- Carousel -->

我注意到第二张幻灯片有一个活动类，但删除它只会打破轮播。

要在HTML中手动设置活动类，只需将active类添加到以下元素中：
<li data-target="#myCarousel" data-slide-to="1" class="active"></li> <div class="item active"> <!-- for slide 2 --> 在本演示中：
<link rel="stylesheet" type="text/css" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript" src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<!-- Carousel -->
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class=""></li>
<li data-target="#myCarousel" data-slide-to="1" class="active"></li>
<li data-target="#myCarousel" data-slide-to="2" class=""></li>
</ol>
<div class="carousel-inner">
<div class="item">
<img src="https://picsum.photos/800/300?image=1" alt="First slide">
<div class="container">
<div class="carousel-caption">
<h1>Project 1</h1>
</div>
</div>
</div>
<div class="item active">
<img src="https://picsum.photos/800/300?image=3" alt="Second slide">
<div class="container">
<div class="carousel-caption">
<h1>Project 2</h1>
</div>
</div>
</div>
<div class="item">
<img src="https://picsum.photos/800/300?image=4" alt="Third slide">
<div class="container">
<div class="carousel-caption">
<h1>Project 3</h1>
</div>
</div>
</div>
</div>
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
但是，这样做不会在页面刷新后持续存在。或者至少肯定不会以动态的方式做到这一点。如果您要使用Javascript加载活动幻灯片，那么您不需要手动设置active课程。只需使用您要导航到的一侧的基于零的索引调用.carousel(index)，如下所示：
$('#myCarousel').carousel(1);
$(function() {
$('#myCarousel').carousel(1);
}); <link rel="stylesheet" type="text/css" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript" src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<!-- Carousel -->
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1" class=""></li>
<li data-target="#myCarousel" data-slide-to="2" class=""></li>
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="https://picsum.photos/800/300?image=1" alt="First slide">
<div class="container">
<div class="carousel-caption">
<h1>Project 1</h1>
</div>
</div>
</div>
<div class="item">
<img src="https://picsum.photos/800/300?image=3" alt="Second slide">
<div class="container">
<div class="carousel-caption">
<h1>Project 2</h1>
</div>
</div>
</div>
<div class="item">
<img src="https://picsum.photos/800/300?image=4" alt="Third slide">
<div class="container">
<div class="carousel-caption">
<h1>Project 3</h1>
</div>
</div>
</div>
</div>
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
这个百万美元的问题是你如何在页面加载时运行上面的javascript。
答案取决于您如何配置链接和网站。对于这种特殊情况，您需要传递carousel一个整数，并且搜索属性始终返回一个字符串，即使它是一组数字。因此，您应该使用new and improved answer to your linked question：
$(function(){
function getParameterByName(key) {
key = key.replace(/[*+?^$.\[\]{}()|\\\/]/g, "\\$&"); // escape RegEx meta chars
var match = location.search.match(new RegExp("[?&]" + key + "=([^&]+)(&|$)"));
var slide = match && decodeURIComponent(match[1].replace(/\+/g, " "));
if (Math.floor(slide) == slide && $.isNumeric(slide))
return parseInt(slide);
else
return 0;
}
var slideNumber = getParameterByName('slide');
$('#myCarousel').carousel(slideNumber);
});
假设您要传递?slide=之类的查询字符串，那么该信息应该在window.location.search属性中提供。
StackSnippets或jsFiddle似乎都没有通过location.search。但是，这是一个扼杀这种工作的人：
你可以看到在这个地址工作：

需要说我是新手，我使用Mobirise作为支持。 话虽如此，我在你的答案中找不到（或者没有理解）的是如何创建一个链接来打开一个特定的幻灯片，用户端，也许在网址的末尾添加一些内容？我用mobirise创建了一个bootstrap carousel样本供你查看。 gallery link
