以下是一个简单的示例代码,演示如何手动设计一个视频播放器,并实现基本的播放、暂停和快进功能。请注意,这只是一个基础的示例,可能需要根据具体需求进行调整和扩展。
HTML代码:
<!DOCTYPE html>
<html>
<head>
    <title>视频播放器</title>
    <link rel="stylesheet" href="video-player.css">
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
    <div class="video-container">
        <video id="myVideo" width="100%" controls>
            <source src="video.mp4" type="video/mp4">
        </video>
        <div class="controls">
            <button id="playPauseBtn"><i class="fa fa-play"></i></button>
            <span id="currentTime">00:00</span> / 
            <span id="duration">00:00</span>
            <button id="fullscreenBtn"><i class="fa fa-expand"></i></button>
        </div>
    </div>
    <script src="video-player.js"></script>
</body>
</html>
CSS样式表(video-player.css):
.video-container {
    position: relative;
}
.controls {
    position: absolute;
    bottom: 10px;
    left: 10px;
}
.controls button {
    background-color: transparent;
    border: none;
    color: white;
    font-size: 20px;
    cursor: pointer;
}
#currentTime, #duration {
    color: white;
}
JavaScript代码(video-player.js):
$(document).ready(function() {
    var video = document.getElementById("myVideo");
    var playPauseBtn = document.getElementById("playPauseBtn");
    var currentTimeSpan = document.getElementById("currentTime");
    var durationSpan = document.getElementById("duration");
    var fullscreenBtn = document.getElementById("fullscreenBtn");
    // 播放/暂停按钮点击事件
    playPauseBtn.addEventListener('click', function() {
        if (video.paused) {
            video.play();
            playPauseBtn.innerHTML = '<i class="fa fa-pause"></i>';
        } else {
            video.pause();
            playPauseBtn.innerHTML = '<i class="fa fa-play"></i>';
        }
    });
    // 视频时间更新事件
    video.addEventListener('timeupdate', function() {
        currentTimeSpan.textContent = formatTime(video.currentTime);
    });
    // 视频元数据加载完成事件
    video.addEventListener('loadedmetadata', function() {
        durationSpan.textContent = formatTime(video.duration);
    });
    // 全屏按钮点击事件
    fullscreenBtn.addEventListener('click', function() {
        if (video.requestFullscreen) {
            video.requestFullscreen();
        } else if (video.mozRequestFullScreen) { // Firefox
            video.mozRequestFullScreen();
        } else if (video.webkitRequestFullscreen) { // Chrome, Safari and Opera
            video.webkitRequestFullscreen();
        } else if (video.msRequestFullscreen) { // IE/Edge
            video.msRequestFullscreen();
        }
    });
     // 辅助函数,将秒数转换为时分秒格式(00:00)
     function formatTime(time) {
         var minutes = Math.floor(time / 60);
         var seconds = Math.floor(time % 60);
         return padZero(minutes) + ":" + padZero(seconds);
     }
     // 辅助函数,在数字前面补零
     function padZero(num) {
         return (num < 10 ? "0" : "") + num;
     }
});
确保视频文件(video.mp4)、CSS样式表(video-player.css)和字体库等文件存在,并与HTML文件在同一目录下。请使用适当的字体图标库,如Font Awesome,确保相关图标能够正常显示。
注意:上述示例中的代码只实现了基本的播放、暂停和全屏功能,并未包含快进等高级功能。如果需要实现更复杂的功能,可能需要对代码进行修改和扩展。
