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。
