前言:音乐播放器是前端开发中的一个经典项目,通过它可以掌握很多核心技术,如音频处理、DOM操作、事件监听、动画效果等。这个项目不仅能提升前端开发的技能,还能让开发者深入理解JavaScript与HTML的协同作用。
页面展示:
歌曲页面+列表(html代码):
音乐
下面有详细的注释讲解,大家可以对照着上图中的结构进行理解,当然也可以自己写,大家了解我的思路就行
<div class="wrapper"><div class="player-warp"><!-- 歌曲信息卡片(隐藏页面) --><div class="player-info"><div class="info"><div class="name"><h4>我记得</h4></div><div class="singer-album">赵雷-署前街少年</div><div class="music-progress"><!-- 时间显示 --><div class="music-progress-top"><!-- 当前时间 --><span class="current-time">00:00</span><!-- 歌曲总时间 --><span class="time">05:29</span></div><!-- 音乐进度线 --><div class="music-progress-bar"><!-- 绘制播放线 --><div class="music-progress-line"></div></div></div></div></div><!-- 歌曲控制页面 --><div class="player-control"><div class="cover"><img src="" alt=""></div><!-- 控制按钮 --><div class="control"><i id="prevBtn" class="iconfont"></i><i id="playBtn" class="iconfont paused"></i><i id="nextBtn" class="iconfont"></i><i id="openModal" class="iconfont"></i></div></div></div></div><!-- 设置音乐背景页面 --><div class="bg"></div><!-- 绘制歌曲列表 --><div class="modal"><div class="modal-box"><!-- 设置模块头部内容 --><div class="modal-box-top"><div class="modal-title"><h3>音乐列表</h3></div><div class="modal-close"><!-- 放置让模块消失的图标 --><i class="iconfont"></i></div></div><div class="modal-wrapper"><!-- 容器 --><ul class="song-list"></ul></div></div></div><!-- 音乐--><audio src=""></audio><script src="./js/jquery.js"></script>
页面功能介绍:
1.点击播放按钮,音乐开始播放,歌曲信息将自然弹出,页面中的圆形图片开始旋转
2.点击前进和后退按钮,音乐和页面信息将进行相应改变
3.点击模块列表内容,可播放该音乐
js功能实现:
家人们我是通过jQuery实现的
1.使用ajax请求音乐数据
通过ajax请求数据,并且调用更新页面数据的函数,在页面中显示第一个歌曲, 添加音乐列表
let musicList = [];let currentIndex = 0; // 当前播放音乐的下标// Ajax 获取音乐数据$.ajax({type: "GET",url: "./music.json",success: function (data) {musicList = data;render(musicList[currentIndex]); // 渲染当前音乐renderMusicList(musicList); // 渲染音乐列表}});
2.页面渲染信息函数:
获得jQuery包装级对象包装级对象,并且通过text()方法,在对象中添加数据
// 渲染音乐详情function render(data) {$(".name h4").text(data.name);$(".time").text(data.time);$(".singer-album").text(`${data.singer} - ${data.album}`);$(".cover img").attr("src", data.cover);$("audio").attr("src", data.audio_url);$('.bg').css({background: `url("${data.cover}") no-repeat center center`,"background-size": "cover"});}
3.播放和暂停音乐:
设置点击播放按钮,将暂停按钮变成播放按钮,并且显示歌曲信息,大家可以通过上面视频了解
// 绑定播放按钮事件$("#playBtn").on("click", togglePlay); // 播放与暂停音乐function togglePlay() {//返回dom对象let audio = $("audio").get(0);if (audio.paused) {$("#playBtn").removeClass("paused").addClass("running").html('');$(".player-info").animate({ top: '-95%' }, 'slow');$(".cover").css({ "animation-play-state": "running" });audio.play();} else {$("#playBtn").removeClass("running").addClass("paused").html('');$(".player-info").animate({ top: '0%' }, 'slow');$(".cover").css({ "animation-play-state": "paused" });audio.pause();}}
4.渲染音乐列表:
通过js动态添加歌曲列表
// 渲染音乐列表function renderMusicList(list) {$(".song-list").empty();$.each(list, function (index, item) {let isPlaying = (index == currentIndex && !$("audio").get(0).paused);let $li = $(`<li id="${index}" class="${index == currentIndex ? 'playing' : ''}"><span>${index + 1}.${item.name} - ${item.singer}</span> <span class="iconfont">${isPlaying ? '' : ''}</span></li>`);$(".song-list").append($li);});}
5.更新播放函数:
这个方法会被重复利用,所以封装起来 ,更新当前音乐信息,更新列表
// 更新并播放音乐function updateAndPlay() {render(musicList[currentIndex]);$("#playBtn").trigger("click"); renderMusicList(musicList); }
6.上下按钮点击事件:
点击前进和后退按钮更换歌曲事件,通过currentIndex变化更换当前歌词(因为当前歌词是通过currentIndex下标进行控制的)
// 绑定上一首、下一首按钮事件$("#prevBtn").on("click", playPrev);// 播放上一首音乐function playPrev() {currentIndex = (currentIndex > 0) ? currentIndex - 1 : musicList.length - 1;updateAndPlay();}$("#nextBtn").on("click", playNext);// 播放下一首音乐function playNext() {currentIndex = (currentIndex < musicList.length - 1) ? currentIndex + 1 : 0;updateAndPlay();}
7.更新音乐条的进度:
根据当前音乐的时间,获得值的百分比赋值给进度表的宽度
// 格式化时间function formatTime(time) {let min = Math.floor(time / 60);let sec = Math.floor(time % 60);return `${min < 10 ? '0' : ''}${min}:${sec < 10 ? '0' : ''}${sec}`;}// 更新播放时间和进度条$("audio").on("timeupdate", function () {let audio = $("audio").get(0);let currentTime = audio.currentTime || 0;let duration = audio.duration || 0;$(".current-time").text(formatTime(currentTime));$(".time").text(formatTime(duration));let value = (currentTime / duration) * 100;$(".music-progress-line").css({ width: value + "%" });});
8.显示模块列表:
点击两个小图标点开音乐列表和关闭音乐列表
// 打开和关闭音乐列表弹窗$("#openModal").on("click", function () {$(".modal").css({ display: "block" });renderMusicList(musicList); // 渲染音乐列表});$(".modal-close").on("click", function () {$(".modal").css({ display: "none" });});
9.点击音乐列表播放音乐事件:
点击列表相应歌曲播放点击歌曲
// 点击音乐列表播放对应歌曲$(".song-list").on("click", "li", function () {currentIndex = parseInt($(this).attr("id"));updateAndPlay(); // 播放选择的音乐});
10.音乐结束事件:
这个我设置的是 playNext () 播放下一个歌曲,大家还可以自己进行其他操作
// 监听音乐播放完毕的事件,自动播放下一首$("audio").on("ended", function () {playNext();});
