// 预播放，每隔50ms获取一次音频时长 audioCtx.onCanplay(async () => { this.playAudio(); let duration = 0; await new Promise((resolve) => { const timer = setInterval(() => { if (Math.floor(audioCtx.duration) !== 0) { clearInterval(timer); resolve(1); }}, 50); }); this.pauseAudio(); duration = Math.floor(audioCtx.duration); this.audioStatus.duration = Math.max(1, duration); this.audioStatus.loaded = true; }); 目前的方案是这样比较合理 https://www.jackchanel.top/
