您好，我發(fā)現(xiàn)這個(gè)腳本可以讓您在瀏覽器中錄制音頻文件，因此它適用于除 Edge 之外的大多數(shù)瀏覽器。所以在頁(yè)面加載時(shí)我得到這個(gè)錯(cuò)誤。錯(cuò)誤 0：未定義“MediaRecorder”當(dāng)我按下錄制按鈕時(shí)，我得到了這個(gè)錯(cuò)誤。0: 'rec' 未定義然后當(dāng)我按下停止時(shí)，我得到了這個(gè)錯(cuò)誤。0: 'rec' 未定義所以我不知道如何讓它在 Edge 上工作。我試圖弄亂它，但我仍然不知道怎么弄，而且我在網(wǎng)上找不到任何可以幫助我解決這個(gè)問(wèn)題的資源。這是代碼navigator.mediaDevices.getUserMedia({    audio: true  })  .then(stream => {    handlerFunction(stream)  })function handlerFunction(stream) {  rec = new MediaRecorder(stream);  rec.ondataavailable = e => {    audioChunks.push(e.data);    if (rec.state == "inactive") {      let blob = new Blob(audioChunks, {        type: 'audio/mpeg-3'      });      recordedAudio.src = URL.createObjectURL(blob);      recordedAudio.controls = true;      recordedAudio.autoplay = true;      sendData(blob)    }  }}function sendData(data) {}record.onclick = e => {  console.log('I was clicked')  record.disabled = true;  record.style.backgroundColor = "blue"  stopRecord.disabled = false;  audioChunks = [];  rec.start();}stopRecord.onclick = e => {  console.log("I was clicked")  record.disabled = false;  stop.disabled = true;  record.style.backgroundColor = "red"  rec.stop();}#record {  background-color: red;  /* Green */  border-width: medium;  border-color: black;  color: white;  padding: 20px;  text-align: center;  text-decoration: none;  display: inline-block;  font-size: 16px;  margin: 4px 2px;  cursor: pointer;  max-width: 50%;  max-height: 15%;  border-radius: 50%;  left: 100px;  right: 100px;  position: relative;}#stopRecord {  background-color: green;  /* Green */  border-width: medium;  border-color: black;  color: white;  padding: 20px;  text-align: center;  text-decoration: none;  display: inline-block;  font-size: 16px;  margin: 4px 2px;  cursor: pointer;  max-width: 50%;  max-height: 15%;  border-radius: 50%;  left: 100px;  right: 100px;  position: relative;}h2 {  left: 100px;  position: relative;}
