chrome限制自动播放声音解决办法：

1. 进入网站设置，声音设为允许。

2. 写方法判断是否有自动播放权限，若没有则诱导用户对网站产生交互，以便正常播放声音。此方法每次进入网站都需产生交互才可正常播放声音。

function getSoundAccess(){var strAudio = "<audio id='audioPlay' src='./images/sounds/sound.mp3' hidden='true'>";if($("body").find("audio").length<=0){$("body").append(strAudio);}var audio = document.getElementById( "audioPlay" );var promise = audio.play();if(promise !== undefined) {promise.then(function(){//audio.play();}).catch(function(){//此处进行弹窗提醒，诱导用户对网站进行点击})}}
