我正在尝试创建一些网站模板来帮助我提高前端开发技能,因为我目前在后端工作方面做得更好。
我试图在某种程度上复制我自己网站的风格(https://thomas-smyth.co.uk/),这是一个简单的引导模板。然而,我想用Youtube视频代替标题中的静态照片。我一开始就减少了我网站中使用的模板,并将其精简到我认为可以在不破坏标题的情况下获得的最小数量。
我在这个地方找到了一些代码,展示了如何将Youtube视频设置为整个页面的背景,而不是页面特定部分的背景。我该怎么做?注意-它必须从YouTube上播放,因为我的主机不允许我在他们的服务器上播放视频。
我当前的代码:

我用Youtube视频背景创建了一个简单的例子,使用视频流的直接链接(仅限JS/CSS解决方案)。请随意在JSfiddle上查看。此外,您可以将公共Google Image代理URL更新为任何公共或您自己的CORS代理。
var vid = "FUUw3zNTXH8",
streams,
video_tag = document.getElementById("video");
fetch("https://images" + ~~(Math.random() * 33) + "-focus-opensocial.googleusercontent.com/gadgets/proxy?container=none&url=" + encodeURIComponent("https://www.youtube.com/watch?hl=en&v=" + vid)).then(response => response.text()).then(function(data) {
if (data) {
streams = parse_youtube_meta(data);
video_tag.src = streams['hls'] || streams['720pna'] || streams['480pna'] || streams['720p'] || streams['480p'] || streams['360p'] || streams['240p'] || streams['144p'];
} else {
alert('Youtube API Error');
}
});
function parse_youtube_meta(rawdata) {
var regex = /(?:ytplayer.configs*=s*|ytInitialPlayerResponses?=s?)(.+?)(?:;var|;(function|)?;s*if|;s*if|;s*ytplayer.|;s*</script)/gmsu;
rawdata = rawdata.split('window.getPageData')[0];
rawdata = rawdata.replace('ytInitialPlayerResponse = null', '');
rawdata = rawdata.replace('ytInitialPlayerResponse=window.ytInitialPlayerResponse', '');
rawdata = rawdata.replace('ytplayer.config={args:{raw_player_response:ytInitialPlayerResponse}};', '');
var matches = regex.exec(rawdata);
var data = matches && matches.length > 1 ? JSON.parse(matches[1]) : false;
console.log(data);
var streams = [],
result = {};
if (data.streamingData && data.streamingData.adaptiveFormats) {
streams = streams.concat(data.streamingData.adaptiveFormats);
}
if (data.streamingData && data.streamingData.formats) {
streams = streams.concat(data.streamingData.formats);
}
streams.forEach(function(stream, n) {
var itag = stream.itag * 1,
quality = false,
itag_map = {

};
//if (stream.type.indexOf('o/mp4') > 0) console.log(stream);
if (itag_map[itag]) result[itag_map[itag]] = stream.url;
});
if (data.streamingData && data.streamingData.hlsManifestUrl) {
result['hls'] = data.streamingData.hlsManifestUrl;
}
return result;

我在这里找到了一个教程,解释了如何将视频设置为页面的背景。本教程展示了如何将视频设置为全屏背景,以及仅为所需的特定页面设置背景。
你需要设置你的Html和CSS部分来实现这种背景。教程页面包括一些可以复制的示例代码。
希望它能帮助你。
多亏了上面的内容,当旧方法失效时,我实际上想出了一个不同的方法。也许不如上面的好,但它对我来说很有效。这是一个WP插件,用户可以设置高度和其他一些选项,如视频ID、静音和音量。还使用YouTube API。
可以在我的网站顶部看到:https://neotropicworks.com/
// Output from plugin onto page using 'wp_add_inline_script' to JS file below
var video_id = "qnTsIVYxYkc",video_mute = true,video_volume = 50;
// JS file
var player;
var tag = document.createElement('script');
tag.src = "//www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
function onYouTubeIframeAPIReady() {
player = new YT.Player('youtube-header-player', {
videoId: video_id,
playerVars: {
playlist: video_id,
loop: 1
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
event.target.playVideo();
if(video_mute){
player.mute();
} else {
player.setVolume(video_volume);
}
}
function onPlayerStateChange(event) {
if (event.data === YT.PlayerState.ENDED) {
player.playVideo();
}
}
在样式表中
.video-wrapper{width: 100%;overflow: hidden;position: relative;}
.video-container {position: absolute;width: auto;top: -50%;left: 0;right: 0;bottom: -50%;}
.video-bg {background: none;position: absolute;top: 0;right: 0;bottom: 0;left: 0;z-index: 1;}
.video-bg .video-fg,.video-bg iframe,.video-bg video {position: absolute;top: 0;left: 0 !important;width: 100% !important;height: 100%;}
下面是用户根据他们想要的高度生成的输出。他们为不同的设备设置大小,窗口大小以更好地控制。
.video-wrapper{height: 400px;}
.video-container {height: 800px;}
@media (min-width: 768px) and (max-width: 991px) {
.video-wrapper{height: 300px;}
.video-container {height: 600px;}
}
@media (max-width:767px) {
.video-wrapper{height: 200px;}
.video-container {height: 400px;}
}
HTML
<div class="video-wrapper">
<div class="video-container">
<div class="video-bg">
<div class="video-fg" id="youtube-header-player"></div>
</div>
</div>
</div>
只是分享我制作的一个简单的jQuery插件,让你的生活更轻松。
您只需要选择一个具有data-youtube
属性的元素,该属性仅包含youtube链接或ID。其他一切都由插件完成,包括嵌入api脚本注入和CSS。
这是一个快速使用示例。你可以在这里看到它的作用。
<div id="ytbg" data-youtube="https://www.youtube.com/watch?v=eEpEeyqGlxA"></div>
<script type="text/javascript">
jQuery(document).ready(function() {
$('[data-youtube]').youtube_background();
});
</script>
