<h2>高级功能实现</h2>
<h3>自定义播放控制</h3>
<p>通过JavaScript API实现自定义控制条：</p>
<pre><code>const video = document.getElementById('myVideo');
// 播放/暂停控制
function togglePlay() {
if (video.paused) {
video.play();
} else {
video.pause();
}
}
// 进度条控制
video.ontimeupdate = function() {
const progress = (video.currentTime / video.duration) * 100;
document.getElementById('progressBar').style.width = `${progress}%`;
};
// 全屏切换
function toggleFullscreen() {
if (!document.fullscreenElement) {
video.requestFullscreen();
} else {
document.exitFullscreen();
}
}</code></pre>
<div class="video-demo">
<h3>自定义播放器演示</h3>
<video id="customVideo" width="100%" poster="https://via.placeholder.com/800x450/2c3e50/ffffff?text=Custom+Player">
<source src="https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_1mb.mp4" type="video/mp4">
</video>
<div class="controls">
<button onclick="togglePlay()">播放/暂停</button>
<button onclick="video.volume += 0.1">音量+</button>
<button onclick="video.volume -= 0.1">音量-</button>
<button onclick="toggleFullscreen()">全屏</button>
</div>
</div>
<h3>响应式视频设计</h3>
<p>确保视频在不同设备上完美显示：</p>
<pre><code>/* 响应式视频样式 */
.video-container {
position: relative;
padding-bottom: 56.25%; /* 16:9比例 */
height: 0;
overflow: hidden;
}
.video-container video {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}</code></pre>
