突然想在博客的文章里放一点音乐。
这应该不是什么大问题吧,然而看到的大多数攻略都是使用网易云的iFrame外部链接,缺点是延迟很严重,还有配合Hexo的插件,比如Aplayer——为Github Page + Jekyll提供的解决方案似乎很少,并且也不想折腾太大的插件。
经过一番搜索,终于在这篇文章里看到了一种可行方案。
配置
主要分为以下三步
第一步:下载open-embed.html(点进链接-右键-存储为)源码如下
<style>
.videoWrapper {
position: relative;
padding-bottom: 56.333%;
height: 0;
background: black;
}
.videoWrapper iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
border: 0;
}
</style>
<script>
function get_youtube_id(url) {
var p = /^(?:https?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:embed\/|v\/|watch\?v=|watch\?.+&v=))((\w|-){11})(?:\S+)?$/;
return (url.match(p)) ? RegExp.$1 : false;
}
function vimeo_embed(url,el) {
var id = false;
$.ajax({
url: 'https://vimeo.com/api/oembed.json?url='+url,
async: true,
success: function(response) {
if(response.video_id) {
id = response.video_id;
if(url.indexOf('autoplay=1') !== -1) var autoplay=1; else var autoplay=0;
if(url.indexOf('loop=1') !== -1) var loop=1; else var loop=0;
var theInnerHTML = '<div class="videoWrapper"><iframe src="https://player.vimeo.com/video/'+id+'/?byline=0&title=0&portrait=0';
if(autoplay==1) theInnerHTML += '&autoplay=1';
if(loop==1) theInnerHTML += '&loop=1';
theInnerHTML += '" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></div>';
el.innerHTML = theInnerHTML;
}
}
});
}
function video_embed() {
var p = document.getElementsByTagName('p');
for(var i = 0; i < p.length; i++) {
//check if this is an external url (that starts with https:// or http://
if (p[i].innerHTML.indexOf("http://") == 0 ||
p[i].innerHTML.indexOf("https://") == 0) {
var youtube_id = get_youtube_id(p[i].innerHTML);
if(youtube_id) {
if(p[i].innerHTML.indexOf('autoplay=1') !== -1) var autoplay=1; else var autoplay=0;
if(p[i].innerHTML.indexOf('loop=1') !== -1) var loop=1; else var loop=0;
var theInnerHTML = '<div class="videoWrapper"><iframe width="720" height="420" src="https://www.youtube.com/embed/' + youtube_id + '?rel=0&showinfo=0';
if(autoplay==1) theInnerHTML += '&autoplay=1';
if(loop==1) theInnerHTML += '&loop=1&playlist='+youtube_id+'&version=3';
theInnerHTML += '" frameborder="0" allowfullscreen></iframe></div>';
p[i].innerHTML = theInnerHTML;
}
if(p[i].innerHTML.indexOf('vimeo.com') !== -1) {
//ask vimeo for the id and place the embed
vimeo_embed(p[i].innerHTML,p[i]);
}
}
}
}
video_embed();
function mp3_embed() {
var p = document.getElementsByTagName('p');
for(var i = 0; i < p.length; i++) {
if(p[i].innerHTML.indexOf('.mp3') !== -1) {
var str = p[i].innerHTML.split('?');
if(str.length == 1) str[1] = '';
var str1 = str[1];
str1 = str1.replace('&','').replace('&','');
str1 = str1.replace('autoplay=1','').replace('autoplay=0','');
str1 = str1.replace('loop=1','').replace('loop=0','');
str1 = str1.replace('controls=0','').replace('controls=1','');
if (str[0].lastIndexOf('.mp3', str[0].length - 4) === str[0].length - 4 && str1.length == 0) {
if(str[1].indexOf('autoplay=1') !== -1) var autoplay=1; else var autoplay=0;
if(str[1].indexOf('loop=1') !== -1) var loop=1; else var loop=0;
if(str[1].indexOf('controls=0') !== -1) var controls=0; else var controls=1;
var newInnerHTML = '<audio';
if(autoplay==1) newInnerHTML += ' autoplay';
if(loop==1) newInnerHTML += ' loop';
if(controls==1) newInnerHTML += ' controls';
newInnerHTML += '><source src="'+str[0]+'" type="audio/mpeg">Your browser does not support the audio element.</audio>';
p[i].innerHTML = newInnerHTML;
}
}
}
}
mp3_embed();
</script>
第二步:将上述文件放入Jekyll项目的”_include”文件夹内。
第三步:找到上述文件夹内的_layout.html文件,修改底部内容为:
调用
借助七牛云之类的图床或云端存储,将需要的音乐文件上传至图床,并获得外链。
然后,在Markdown中直接使用<p>音乐外链url</p>
这样的格式,即可获得如下效果的播放器(以下音乐为「阿保剛-Der Mond Das Meer」)
