当然可以!以下是一些代码示例:
1. HTML代码
```html
<div class="player">
<audio id="audio-player"></audio>
<div class="controls">
<button id="play-button">Play</button>
<button id="pause-button">Pause</button>
<input type="range" id="volume-slider" min="0" max="1" step="0.01" value="1">
<input type="range" id="progress-slider" min="0" max="100" value="0">
</div>
<div class="playlist">
<ul id="song-list"></ul>
</div>
</div>
```
2. CSS代码
```css
.player {
background-color: #f2f2f2;
border: 1px solid #ccc;
padding: 10px;
max-width: 500px;
margin: 0 auto;
}
.controls {
display: flex;
justify-content: space-between;
align-items: center;
margin-bottom: 10px;
}
.controls button {
padding: 5px;
border: none;
background-color: #333;
color: #fff;
cursor: pointer;
}
.playlist {
margin-top: 10px;
}
.playlist ul {
list-style-type: none;
margin: 0;
padding: 0;
}
.playlist li {
padding: 5px;
cursor: pointer;
}
.playlist li:hover {
background-color: #eee;
}
```
3. JavaScript代码
```javascript
// 获取DOM元素
const audioPlayer = document.getElementById('audio-player');
const playButton = document.getElementById('play-button');
const pauseButton = document.getElementById('pause-button');
const volumeSlider = document.getElementById('volume-slider');
const progressSlider = document.getElementById('progress-slider');
const songList = document.getElementById('song-list');
// 定义歌曲列表数组
const playlist = [
{name: 'Song A', artist: 'Artist A', url: 'path/to/song-A.mp3'},
{name: 'Song B', artist: 'Artist B', url: 'path/to/song-B.mp3'},
// ...
];
// 遍历歌曲列表,将每首歌曲添加到DOM中
playlist.forEach((song, index) => {
const li = document.createElement('li');
li.textContent = `${song.name} - ${song.artist}`;
li.setAttribute('data-index', index);
songList.appendChild(li);
});
// 定义当前播放的歌曲索引
let currentSongIndex = 0;
// 定义播放器控制函数
function play() {
audioPlayer.src = playlist[currentSongIndex].url;
audioPlayer.play();
}
function pause() {
audioPlayer.pause();
}
function setVolume(volume) {
audioPlayer.volume = volume;
}
function setProgress(progress) {
audioPlayer.currentTime = progress / 100 * audioPlayer.duration;
}
// 绑定事件监听器
playButton.addEventListener('click', play);
pauseButton.addEventListener('click', pause);
volumeSlider.addEventListener('input', (event) => setVolume(event.target.value));
progressSlider.addEventListener('input', (event) => setProgress(event.target.value));
songList.addEventListener('click', (event) => {
if (event.target.tagName === 'LI') {
currentSongIndex = Number(event.target.getAttribute('data-index'));
play();
}
});
// 监听播放器事件,更新进度条
audioPlayer.addEventListener('timeupdate', () => {
const progress = audioPlayer.currentTime / audioPlayer.duration * 100;
progressSlider.value = progress;
});
```
这只是一个简单的音乐播放器示例,仅供参考。您可以根据您的需求进行自定义和扩展。
