audio因微信省流量等策略会取消自动播放
function audioAutoPlay(id){
var audio = document.getElementById(id),
play = function(){
audio.play();
document.removeEventListener("touchstart",play, false);
};
audio.load();
audio.play();
document.addEventListener("WeixinJSBridgeReady", function () {//微信
audio.load();
play();
}, false);
document.addEventListener('YixinJSBridgeReady', function() {//易信
play();
}, false);
document.addEventListener("touchstart",play, false);
}
