我在做一個(gè) HTML5 游戲。我使用createjs來(lái)預(yù)加載圖像。圖像預(yù)加載完成后，需要自動(dòng)播放背景音樂(lè)。我知道 chrome 的新音頻政策。我很困惑我使用函數(shù)handleComplete來(lái)觸發(fā)音頻。為什么它仍然不起作用？我應(yīng)該如何使它工作？這是我的代碼：function Sound (id_str){ this.id = id_str; }Sound.prototype.play = function () {    //there are other logics, but can simply like below    let audio = document.getElementById(this.id);    audio.play().catch(e =>console.log(e));};var audio_bg = new Sound('bgm_id');windows.onload = function preload (handleFileProgress,handleComplete){    let manifest = [...];    loader = new createjs.LoadQueue(false);    loader.setMaxConnections(100);    loader.maintainScriptOrder=true;    loader.installPlugin(createjs.Sound);    loader.loadManifest(manifest);    loader.addEventListener('progress', handleFileProgress);     loader.addEventListener('complete', handleComplete);};function handleFileProgress(){...}function handleComplete(){    //...    audio_bg.play();}我發(fā)現(xiàn)的錯(cuò)誤是：NotAllowedError: play() failed because the user didn't interact with the document first.
