本文通过Html+CSS+jQuery开发仿QQ版的音乐播放器，是前端技术的综合应用，所用素材来源于网络，仅供学习分享使用，如有不足之处，还请指正。

涉及知识点

在本例中用到的知识点如下，按jQuery和CSS进行区分：

jQuery 是一个 JavaScript 库， 极大地简化了 JavaScript 编程，常见知识点如下：

  1. 通过标签获取jQuery对象：var $audio =$("audio");
  2. 通过选择符获取jQuery对象并设置文本内容：$(".music_progrss_time").text(timeStr);
  3. 通过选择符，标签名获取对象并获取第i个子元素：$(".song_lyric ul li").eq(index);
  4. 通过ajax异步获取数据并刷新页面：$.ajax({});
  5. 通过类选择符获取元素并进行隐藏或显示：$(this).find(".list_menu").stop().fadeIn(100);
  6. 通过委托动态设置单击事件，主要针对动态生成元素：$(".content_list").delegate(".list_check", "click", function() {});
  7. 通过addClass添加类，removeClass删除类，toggleClass切换类，hasClass是否包含类
  8. 获取与对象同级的兄弟节点：$musicList.siblings();
  9. 触发相关事件：$(".music_next").trigger("click");

CSS通过使用 CSS 我们可以大大提升网页开发的工作效率！本例使用知识点如下：

  1. 设置距离左边的距离：margin-left: 20px; 设置距离右边的距离：margin-right: 20px;
  2. 设置透明度：opacity: 0.6; 值[0,1]从透明到全不透明
  3. 设置背景图片：background: url(../img/player_logo.png) no-repeat 0 0;设置背景颜色和透明度：background: rgba(255,255,255,0.5);
  4. 设置li的样式：list-style: none;
  5. 设置显示样式为行内块：display: inline-block;
  6. 设置圆角：border-radius: 5px;
  7. 设置相对位置：position: relative;
  8. 背景图片的起始坐标：background-position: 0 -75px;

示例效果图及结构划分

本例的示例效果图及结构划分如下所示：

Html核心代码

Header部分代码：主要用于显示logo和登录显示，如下所示：

jQuery功能性核心代码

在本示例中，从功能上区分，主要分为播放模块，进度条模块，歌词模块，各个模块相互独立，所以进行了适当的封装。

播放模块【Play】主要包括歌曲的初始化，播放与暂停，上一首，下一首，播放同步，跳转等功能，核心代码如下：

(function(window){
 function Player($audio){
 return new Player.prototype.init($audio);
 }
 Player.prototype={
 constructor :Player,
 musicList:[],
 currIndex:-1,
 $audio:null,
 audio:null,
 init:function($audio){
  this.$audio=$audio;//jQuey包装对象
  this.audio=$audio.get(0);//原生audio对象
 },
 play:function(index,music){
  console.log(index,music);
  console.log(this.$audio);
  if(this.currIndex==index){
  //同一首音乐，则是暂停，播放之间切换

  if(this.audio.paused){
   this.audio.play();
  }else{
   this.audio.pause();
  }
  }else{
  //不是同一首，重新播放
  this.$audio.attr('src',music.link_url);
  this.audio.play();
  this.currIndex=index;
  }
 },
 preIndex:function(){
  var index=this.currIndex-1;
  if(index<0){
  index=this.musicList.length-1;
  }
  return index;
 },
 nextIndex:function(){
  var index=this.currIndex+1;
  if(index>this.musicList.length-1){
  index=0;
  }
  return index;
 },
 del:function(index){
  this.musicList.splice(index,1);
  if(index<this.currIndex){
  this.currIndex=this.currIndex-1;
  }
 },
 musicTimeUpdate:function(callBack){
  //需要一个回调函数作为参数
  var that=this;
  //监听audio播放事件
  this.$audio.on("timeupdate",function(){
  var duration=that.audio.duration;
  var currentTime=that.audio.currentTime;
  var timeStr=that.formatTime(currentTime,duration);
  //参数是一个回调函数
  callBack(duration,currentTime,timeStr);
  });
 },
 //定义一个格式化时间的方法
 formatTime:function (currentTime,duration){
  //总时长
  var endMin=parseInt(duration/60);
  var endSec=parseInt(duration%60);
  endMin=endMin<10?"0"+endMin:endMin;
  endSec=endSec<10?"0"+endSec:endSec;
  //当前时长
  var curMin=parseInt(currentTime/60);
  var curSec=parseInt(currentTime%60);
  curMin=curMin<10?"0"+curMin:curMin;
  curSec=curSec<10?"0"+curSec:curSec;
  return curMin+":"+curSec+" / "+endMin+":"+endSec;
 },
 musicSeekTo:function(value){
  var that=this;
  var duration=that.audio.duration;
  if(isNaN(duration))return;
  if(isNaN(value))return;
  that.audio.currentTime=duration*value ;
 },
 musicVoiceSeekTo:function(value){
  if(isNaN(value))return;
  if(value<=0 || value>=1) return;
  this.audio.volume=value;
 }
 };
 Player.prototype.init.prototype=Player.prototype;
 window.Player=Player;
})(window);

歌词模块【lyric】，主要包括歌词的加载，解析，同步等功能，核心代码如下：

(function(window){
 function Lyric(path){
 return new Lyric.prototype.init(path);
 }
 Lyric.prototype={
 constructor :Lyric,
 times:[],
 lyrics:[],
 index:-1,
 init:function(path){
  this.path=path;
 },
 loadLyric:function(callBack){
  var that=this;
  $.ajax({
  type: "get",
  dataType:"text",
  contentType: "application/text; charset=utf-8",
  url: that.path,
  success: function(data) {
   //console.log(data);
   that.parseLyric(data);
   callBack();
  },
  error: function(e) {
   console.log(e);
  }
  });
 },
 parseLyric:function(data){
  var that=this;
  //初始化歌词和时间
  that.times=[];
  that.lyrics=[];
  that.index=-1;
  //
  var array=data.split("\n");
  //console.log(array);
  var timeReg=/\[(\d*:\d*\.\d*)\]/;
  $.each(array, function(index,ele) {
  //console.log(ele);
  //
  var lyc=ele.split("]")[1];
  if(lyc==null || lyc.length==1){
   return true;//排除空字符串
  }
  that.lyrics.push(lyc);

  var res=timeReg.exec(ele);
  //console.log(res);
  if(res==null){
   return true; //排除空时间
  }
  var timeStr=res[1];
  var res2=timeStr.split(":");
  var min=parseInt(res2[0]) *60;
  var sec=parseFloat(res2[1]) ;
  var res3=parseFloat( Number(min+sec).toFixed(2));
  //console.log(res3);
  that.times.push(res3);
  });
  console.log(that.times.length +" , "+ that.lyrics.length);
 },
 currentLyric:function(currentTime){
  //console.log(currentTime);
  if(currentTime>this.times[0]){
  this.index++;
  this.times.shift();//删除第一个元素，并返回剩余的数组
  }
  return this.index;
 }
 };
 Lyric.prototype.init.prototype=Lyric.prototype;
 window.Lyric=Lyric;
})(window);

进度条模块【Progress】主要包括：进度条的初始化，单击，拖动，回调等功能，核心代码如下：

(function(window){
 function Progress($progressBar,$progressLine,$progressDot){
 return new Progress.prototype.init($progressBar,$progressLine,$progressDot);
 }
 Progress.prototype={
 constructor :Progress,
 isMove:false,
 init:function($progressBar,$progressLine,$progressDot){
  this.$progressBar=$progressBar;
  this.$progressLine=$progressLine;
  this.$progressDot=$progressDot;
 },
 progressClick:function(callBack){
  //console.log(this.$progressBar);
  var that=this;//此时的this表示Progress
  this.$progressBar.click(function(event){
  //此时的this表示progrssBar点击的对象
  var normalLeft = $(this).offset().left;//控件默认距左边的位置
  var eventLeft = event.pageX;//当前鼠标点击的距左边的位置
  that.$progressLine.css("width",eventLeft-normalLeft);
  that.$progressDot.css("left",eventLeft-normalLeft);
  //计算进度条的比例
  var value=(eventLeft-normalLeft)/$(this).width();
  callBack(value);
  });
 },
 progressMove:function(callBack){
  var that=this;//此时的this表示Progress
  var normalLeft =-1;
  var eventLeft=-1;
  var barWidth=this.$progressBar.width();
  this.$progressBar.mousedown(function(){
  that.isMove=true;
  normalLeft = $(this).offset().left;//控件默认距左边的位置

  $(document).mousemove(function(){
   //此时的this表示progrssBar点击的对象
   eventLeft = event.pageX;//当前鼠标点击的距左边的位置
   var v=eventLeft-normalLeft;
   if(v>=0 && v<=barWidth){
   //判断值的有效范围再赋值
   that.$progressLine.css("width",eventLeft-normalLeft);
   that.$progressDot.css("left",eventLeft-normalLeft);
   }
  });
  });
  $(document).mouseup(function(){
  $(document).off("mousemove");
  that.isMove=false;
  //计算进度条的比例
  var value=(eventLeft-normalLeft)/that.$progressBar.width();
  //鼠标抬起时触发，防止音乐断断续续
  callBack(value);
  });
 },
 setProgress:function(value){
  if(this.isMove)return;
  if(value<0 || value>100){
  return;
  }
  this.$progressLine.css("width",value+"%");
  this.$progressDot.css("left",value+"%");
 }
 };
 Progress.prototype.init.prototype=Progress.prototype;
 window.Progress=Progress;
})(window);

加载流程，包括初始化歌曲列表，歌词信息，注册事件，初始化进度条等功能，本例中的歌曲列表和歌词信息，均是通过ajax从本地文件中获取，核心代码如下：

$(function() {
 var $audio =$("audio");
 var player=new Player($audio);
 var progress=null;
 var voiceProgress=null;
 var lyric=null;
 //1.加载音乐
 getPlayerList();
 //2.注册事件
 initEvent();
 //3.初始化进度条，包括声音
 initProgress();

 //音乐播放同步
 player.musicTimeUpdate(function(duration,currentTime,timeStr){
 //同步时间
 $(".music_progrss_time").text(timeStr);
 //同步进度条
 var value=currentTime/duration *100;
 progress.setProgress(value);
 //实现歌词同步
 var oldIndex=lyric.index;
 var index=lyric.currentLyric(currentTime);
 if(oldIndex==index)return;
 var item=$(".song_lyric ul li").eq(index);
 item.addClass("cur");
 item.siblings().removeClass("cur");
 if(index<0) return;
 $(".song_lyric ul").css({
  marginTop:(-index+2)*40
 });
 })

 //获取列表函数
 function getPlayerList() {
 $.ajax({
  type: "get",
  url: "music_list.json",
  success: function(data) {
  //player.musicList=data;
  //console.log(data);
  var musicList = $(".content_list ul");
  $.each(data, function(index, ele) {
   var item = createMusicItem(index, ele);
   musicList.append(item);
  });
  //默认初始化第一首歌曲信息
  initMusicInfo(data[0]);

  //初始化歌词信息
  initMusicLyric(data[0]);
  },
  error: function(e) {
  console.log(e);
  }
 });
 }
 //定义一个方法，创建一条音乐
 function createMusicItem(index, music) {
 var $item = $("<li class=\"list_music\">\n" +
  "<div class=\"list_check\">\n" +
  "<i></i>\n" +
