首先在网页中嵌入背景音乐，html5代码为：
<script src="http://wuover.qiniudn.com/jquery.js"></script><a class="mscBtn" id="audioBtn" title=‘最幸福的人‘ style="cursor:pointer;"></a><audio id="bgMusic" src="http://cctv3.qiniudn.com/zuixingfuderen.mp3" autoplay="autoplay"></audio>
css样式为：
.pause {background-position: 0 bottom;}.mscBtn {height: 50px;background: #fff url(http://cctv2.qiniudn.com/musicbtn.png) no-repeat;display: block;}通过audio的id即可控制音乐的播放（play()）和暂停（pause()），同时通过改变class改变按钮的背景图片，js代码为（切记要引入jq库）：
$(function(){$("#audioBtn").click(function(){if(music.paused){music.play();$("#audioBtn").removeClass("pause").addClass("play");}else{music.pause();$("#audioBtn").removeClass("play").addClass("pause");}});});改进了下,让网页背景音乐支持多首歌曲，播放完在随机播放下一首并且不会和上一首重复
$(function(){var music = document.getElementById("bgMusic");var musicArr=[//下面对应歌曲链接和歌名，自行添加用,隔开 ??{url:‘http://cctv3.qiniudn.com/tbhdqx.mp3‘,title:"唐伯虎点秋香"}, ??????????????????????????????{url:‘http://cctv3.qiniudn.com/abzxh.mp3‘,title:"敖包再相会"}, ??????????????????????????{url:‘http://cctv3.qiniudn.com/lmzda.mp3‘,title:"辣妹子的爱"}, ??????????????????????????????{url:‘http://cctv3.qiniudn.com/32.mp3‘,title:"32号嫁给你"}, ??{url:‘http://cctv3.qiniudn.com/tongxinjishou.mp3‘,title:"痛心疾首"}, ??{url:‘http://cctv3.qiniudn.com/rgangdst.mp3‘,title:"如果爱能感动上天"}, ??{url:‘http://cctv3.qiniudn.com/cz.mp3‘,title:"车站"}, ??????????????????????????????{url:‘http://cctv3.qiniudn.com/hn.ogg‘,title:"很难"}, ??????????????????????????{url:‘http://cctv3.qiniudn.com/aqlmysdsc.mp3‘,title:"爱情里没有谁对谁错"}, ??{url:‘http://cctv3.qiniudn.com/dlaqdln.mp3‘,title:"丢了爱情丢了你"}, ??????????????????????????????{url:‘http://cctv3.qiniudn.com/cty.mp3‘,title:"闯天涯"}];$("#audioBtn").click(function(){ ???if(music.paused){ ???????music.play(); ???????$("#audioBtn").removeClass("pause").addClass("play"); ???}else{ ???????music.pause(); ???????$("#audioBtn").removeClass("play").addClass("pause"); ???}});function randomMusic(){ ??var isone=$("#bgMusic").attr(‘src‘); ??var noone=musicArr[parseInt(Math.random()*musicArr.length)]; ??if (noone.url==isone){ ??????var noone=musicArr[parseInt(Math.random()*musicArr.length)]; ??} ??$("#bgMusic").attr(‘src‘,noone.url); ??$("#audioBtn").attr(‘title‘,noone.title);} ???randomMusic(); ???$("#bgMusic").on(‘ended‘,function(){ ??????randomMusic(); ???????});});JS实现控制HTML5背景音乐播放暂停
