Hexo博客 | 视频点播页面，如何在博客上优雅地展示B站等平台视频

之前考虑到自己剪了一些vlog，但是直接用iframe嵌入的话页面会很长，而且点开这个页面会自动加载全部视频，感觉很奇怪，并且不能很好的展示，于是写了一个视频点播页面

1. 新建路径页面

首先使用命令新建一个页面：

1	hexo new page video

在index.md里面写入一下内容：

---
title: 我的视频
date: 2020-07-17 20:54:09
comment: true
top_img: false
showToc: true
aside: false
type: "video"
---

<script src="https://unpkg.com/jquery@latest/dist/jquery.min.js"></script>
<script>
function selectVideo(id){
    var src=$("#video-item-"+id).attr("data-src");
    $("#video-select").html("<iframe id='video-iframe' src='"+src+"' scrolling='no' border='0' frameborder='no' framespacing='0' allowfullscreen='true'> </iframe>");
    var iframe = document.getElementById("video-select")
    if(iframe.attachEvent){
      iframe.attachEvent("onreadystatechange", function() {
        if (iframe.readyState === "complete" || iframe.readyState == "loaded") {
          iframe.detachEvent("onreadystatechange", arguments.callee);
        if (document.getElementsByClassName('video-mirror').length>0) {
          console.log("1true")
          $(".video-mirror").attr("style","transform:scaleX(-1);")
          }
        }
      });
    }else{
      iframe.addEventListener("load", function() {
        this.removeEventListener("load", arguments.call, false);
      if (document.getElementsByClassName('video-mirror').length>0) {
        console.log("2true")
        $(".video-mirror").attr("style","transform:scaleX(-1);")
      }
      }, false);
    }
}
$(document).ready(selectVideo(0));
</script>

2. 新建主题页面

在主题路径themes\butterfly-dev\layout\includes\page下新建video.pug：

//if top_img === false
//  h1.page-title= page.title
#video-select.video-select
hr
h3= 视频列表
.videos
  if site.data.video
    each i,index in site.data.video
      div(class="myvideo" onclick=`javascipt:selectVideo(`+index+`)`)
        div(id=`video-item-`+index class="video-item" data-src=url_for(i.link))
          a(href="#video-select")
            img.video-item-cover(src=url_for(i.cover))
        .video-desc
          .video-title
            a(href="#video-select")= i.title
          .video-info= i.description

style.
  .videos{
    display: grid;
    grid-template-columns: repeat(4, 1fr);
    grid-column-gap: 20px;
    grid-row-gap: 20px;
  }
  @media screen and (max-width: 1200px){
    .videos{
      display: grid;
      grid-template-columns: repeat(3, 1fr);
      grid-column-gap: 20px;
      grid-row-gap: 20px;
    }
  }
  @media screen and (max-width: 900px){
    .videos{
      display: grid;
      grid-template-columns: repeat(2, 1fr);
      grid-column-gap: 20px;
      grid-row-gap: 20px;
    }
  }
  @media screen and (max-width: 600px){
    .videos{
      display: grid;
      grid-template-columns: repeat(1, 1fr);
      grid-column-gap: 20px;
      grid-row-gap: 20px;
    }
  }
  .myvideo{
    position: relative;
    width: 100%;
    border: 1px solid var(--mj-card-border);
    border-radius: 12px;
  }
  .video-item{
    overflow: hidden;
    height: 160px;
    border-top-left-radius: 12px;
    border-top-right-radius: 12px;
  }
  .video-item img {
    position: relative;
    width: 100%;
    margin: 0 !important;
    height: 100%;
    transform: scale(1.0);
    transition: .3s;
    object-fit: cover;
  }
  .myvideo:hover .video-item img {
    transition: .3s;
    transform: scale(1.1);
  }
  .video-title{
    padding: 5px 10px;
    font-size: 18px;
    font-weight: bold;
  }
  .video-info{
    font-size: 14px;
    padding: 0 10px;
    color: var(--mj-secondtext);
  }
  .video-select{
    position:relative;
    width:100%;
    height:0;
    padding-bottom:75%;
  }
  .video-select iframe{
    position:absolute;
    width:100%;
    height:100%;
    left:0;
    top:0;
    border-radius: 12px;
  }
!= page.content

3. 注册video页面

在主题路径butterfly/layout/的page.pug文件中注册上述页面模板：

extends includes/layout.pug

block content
  #page
    if top_img === false
      h1.page-title= page.title

    case page.type
      when 'tags'
        include includes/page/tags.pug
      when 'link'
        include includes/page/flink.pug
      when 'categories'
        include includes/page/categories.pug
+     when 'video'
+       include includes/page/video.pug
      default
        include includes/page/default-page.pug

    if page.comments !== false && theme.comments && theme.comments.use
      - var commentsJsLoad = true
      !=partial('includes/third-party/comments/index', {}, {cache: true})

4. 获取B站等平台视频嵌入代码

在视频播放页面通常会有分享按钮，并且一般会提供链接和iframe嵌入两种分享方式，例如我的（顺便求一波关注）：

复制iframe代码，如下：

1	<iframe src="//player.bilibili.com/player.html?aid=937145035&bvid=BV18T4y1D7wj&cid=545915013&page=1" scrolling="no" border="0" frameborder="no" framespacing="0" allowfullscreen="true"> </iframe>

5. 新建data文件

在hexo\source\_data路径下(没有就创建一个文件夹)新建一个数据文件video.yml，把刚才的iframe代码内容转换成：
