H5页面在IOS下不会自动播放音乐的坑

document.addEventListener(‘DOMContentLoaded‘, function () {
    function audioAutoPlay() {
        var audio = document.getElementById(‘bg-music‘);
            audio.play();
        document.addEventListener("WeixinJSBridgeReady", function () {
            audio.play();
        }, false);
    }
    audioAutoPlay();
});
