<content:encoded><![CDATA[<h2 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h2><p>最近一直在 <a href="http://438kan.com/">438kan</a> 上追剧，但是 438kan 自带的播放器嵌套在一个 iframe 中，不能使用网页全屏功能。而使用全屏播放视频时遇到要回复QQ、微信消息的情况则需要不断在全屏/非全屏之间切换，非常麻烦。所以决定研究研究，实现 438kan 的网页全屏功能。</p><h2 id="初次分析"><a href="#初次分析" class="headerlink" title="初次分析"></a>初次分析</h2><p>我们首先在浏览器中打开播放器地址 <a
