[英]Reveal.js – Remove globally set footer from single slide
我正在制作我的第一个 reveal.js 演示文稿,并在 html 文件的正文中设置了全局页脚。 我想删除一张幻灯片的页脚,但是,我不知道该怎么做。
下面是我当前的文件,最后是页脚:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>TITLE</title>
<meta
name="description"
content="DESCRIPTION"
/>
<meta name="author" content="MY NAME" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta
name="apple-mobile-web-app-status-bar-style"
content="black-translucent"
/>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link rel="stylesheet" href="dist/reset.css" />
<link rel="stylesheet" href="dist/reveal.css" />
<link rel="stylesheet" href="dist/theme/black.css" id="theme" />
<!-- Theme used for syntax highlighting of code -->
<link rel="stylesheet" href="plugin/highlight/monokai.css" />
</head>
<body>
<div class="reveal">
<div class="slides">
<section>
<a href="https://example.com/">
<img
src="images/example.png"
alt="Example logo"
style="
height: 360px;
margin: 0 auto 4rem auto;
background: transparent;
"
class="logo"
/>
</a>
<h4>Title of my presentation</h4>
<p style="font-size: 30px">
Subtitle
</p>
</section>
<section>
<section class="center">
<h2>What goes here?</h2>
</section>
<section class="center">
<p>Lorem ipsum dolor sit amet</p>
</section>
<section class="center">
<pre>
<code>
Here is the code
</code>
</pre>
</section>

</div>
</div>
<!-- Default plugins -->
<script src="dist/reveal.js"></script>

});
</script>
<!-- 1. Create hidden footer <div> -->
<div id="hidden" style="display:none;">
<div id="footer">
<div id="footer">Copyright 2022</div>
</div>
</div>
<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<script type="text/javascript">
// 2. On Reveal.js ready event, copy footer <div> into each `.slide-background` <div>
var footer = $('#footer').html();
$('div.reveal').append(footer);
</script>
</body>
</html>
任何提示或建议将不胜感激!
首先,您有一条评论说
在 Reveal.js 就绪事件中,复制页脚
但我在你的代码中看不到。 对我来说,它看起来像一个普通的 append。
现在回答你的问题,你应该听slideChanged
事件并在当前幻灯片是你不希望页脚的幻灯片时删除页脚:
Reveal.on( 'slidechanged', event => {
// event.previousSlide, event.currentSlide, event.indexh, event.indexv
} );
event.currentSlide
是幻灯片的索引,所以你可以通过这种方式检索你想要的幻灯片。 是的,它非常脆弱,因为如果幻灯片的索引发生变化,它就会破裂,但这是唯一的方法......
