解决HTML5中的audio在手机端和微信端的不能自动播

<audio loop src="/photo/aa.mp3" id="audio" aulay preload="auto">

//--创建页面监听，等待微信端页面加载完毕 触发音频播放
document.addEventListener('DOMContentLoaded', function () {
    function audioAutoPlay() {
        var audio = document.getElementById('audio');
            audio.play();
        document.addEventListener("WeixinJSBridgeReady", function () {
            audio.play();
        }, false);
    }
    audioAutoPlay();
});
//--创建触摸监听，当浏览器打开页面时，触摸屏幕触发事件，进行音频播放
document.addEventListener('touchstart', function () {
    function audioAutoPlay() {
        var audio = document.getElementById('audio');
            audio.play();
    }
    audioAutoPlay();
});
