javascript – 设置页眉和页脚reveal.js演示文稿

前端之家收集整理的这篇文章主要介绍了javascript – 设置页眉和页脚reveal.js演示文稿前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我想在演示文稿中设置页眉和页脚.我使用以下问题作为起点: https://github.com/hakimel/reveal.js/issues/806http://www.ciges.net/revealjs_demo/#/

我当前的实现提供了以下输出

据我所知,reveal.js默认使用fixed size for the presentation,宽度为960px,高度为700px.这个尺寸对我来说完全没问题.但是,我希望不在此窗口中修复页眉和页脚.他们需要适应实际的屏幕尺寸.也就是说,我希望左标题与屏幕的左上角对齐.同样对于其他页眉和页脚,另请参见图像.我怎样才能做到这一点?目前看来我的页眉和页脚是固定在默认窗口(960×700).

我在reveal.js 3.2.0中使用以下代码(index.html)

<!doctype html>
<html lang="en">

    <head>
        <Meta charset="utf-8">

解决方法

这是 a slightly more complicated answer,也适用于pdf-export打印版本:

将元素添加幻灯片背景< div> (而不是部分,幻灯片或揭示).这个< div>是动态生成的,所以我们必须等待Reveal.js ready事件.打印时会有轻微的延迟,接着是页眉和页脚移动到位的不必要的动画,但所有页眉/页脚都会根据需要在PDF中呈现.

代码

>样式页眉/页脚< div>所以他们按照需要定位.
>创建隐藏的页眉/页脚< div>
>在Reveal.js就绪事件中,复制页眉/页脚< div>进入每个.slide-background< div>

代码:这可以复制粘贴到reveal.js文件的末尾(在结束< / body>标记之前):

<style type="text/css">
    /* 1. Style header/footer <div> so they are positioned as desired. */
    #header-left {
        position: absolute;
        top: 0%;
        left: 0%;
    }
    #header-right {
        position: absolute;
        top: 0%;
        right: 0%;
    }
    #footer-left {
        position: absolute;
        bottom: 0%;
        left: 0%;
    }
</style>

<!-- 2. Create hidden header/footer <div> -->
<div id="hidden" style="display:none;">
    <div id="header">
        <div id="header-left">HEADER-LEFT</div>
        <div id="header-right">HEADER-RIGHT</div>
        <div id="footer-left">FOOTER-LEFT</div>
    </div>
</div>

<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<script type="text/javascript">
    // 3. On Reveal.js ready event,copy header/footer <div> into each `.slide-background` <div>
    var header = $('#header').html();
    if ( window.location.search.match( /print-pdf/gi ) ) {
        Reveal.addEventListener( 'ready',function( event ) {
            $('.slide-background').append(header);
        });
    }
    else {
        $('div.reveal').append(header);
   }
</script>
