获取语音文件时长

获取语音文件时长一会儿有一会儿没的，百思不得其解。
错误代码：

  const getAudioDuration = async src => {const audio = new Audio(src);const duration = await new Promise(resolve => {if (audio.duration) {return resolve(parseInt(audio.duration * 1000));}audio.addEventListener('loadedmetadata', () => {resolve(parseInt(audio.duration * 1000));});});}；

后来换了个方法：

  const getAudioDuration = async src => {const audio = new Audio(src);return await new Promise(resolve => {const getDuration = event => {event.target.currentTime = 0;event.target.removeEventListener('timeupdate', getDuration);resolve(event.target.duration);};audio.addEventListener('loadedmetadata', e => {const audio = e.target;if (audio.duration === Infinity || isNaN(Number(audio.duration))) {audio.currentTime = 1e101;audio.addEventListener('timeupdate', getDuration);return;}resolve(audio.duration);});});};

完美解决
