需要引入jq以及微信的js
<script src="./jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="./jweixin-1.0.0.js"></script>
<script>function autoPlayMusic() {// 自动播放音乐效果，解决浏览器或者APP自动播放问题
        function musicInBrowserHandler() {musicPlay(true);document.body.removeEventListener('touchstart', musicInBrowserHandler);}document.body.addEventListener('touchstart', musicInBrowserHandler);// 自动播放音乐效果，解决微信自动播放问题
        function musicInWeixinHandler() {musicPlay(true);document.addEventListener("WeixinJSBridgeReady", function () {musicPlay(true);}, false);document.removeEventListener('DOMContentLoaded', musicInWeixinHandler);}document.addEventListener('DOMContentLoaded', musicInWeixinHandler);}function musicPlay(isPlay) {var audio = document.getElementById('audio2');if (isPlay && audio.paused) {audio.play();}if (!isPlay && !audio.paused) {audio.pause();}};autoPlayMusic();// 关闭音乐
$('.music-pic').click(function () {if($('.music-pic').hasClass('close')){document.getElementById("audio2").muted=false;$('.music-pic').removeClass('close');}else {$('.music-pic').addClass('close');document.getElementById("audio2").muted=true;}
});
