一、添加音乐

二、处理兼容

　　　　function audioAutoPlay(id){            var audio = document.getElementById(id);            var play = function() {                document.removeEventListener("WeixinJSBridgeReady", play);                document.removeEventListener("YixinJSBridgeReady", play);                audio.play();                audio.pause();                // document.removeEventListener("touchstart", play, false);            };                        audio.play();            audio.pause();            //weixin            document.addEventListener("WeixinJSBridgeReady", play, false);            //yixin            document.addEventListener('YixinJSBridgeReady', play, false);            // document.addEventListener("touchstart", play, false);            alert(222)        }        audioAutoPlay('Jaudio');

三、开始播放

var audio = document.getElementById('Jaudio'); audio.play();
