MediaRecorder 接口的 error event is fired when an error occurs: for example because recording wasn't allowed or was attempted using an unsupported codec.

冒泡	No
可取消	No
接口	MediaRecorderErrorEvent
事件处理程序特性	onerror

For details of the all the possible errors see the documentation for the event handler property: onerror .

范例

使用 addEventListener to listen for error 事件：

async function record() {
    const stream = await navigator.mediaDevices.getUserMedia({audio: true});
    const recorder = new MediaRecorder(stream);
    recorder.addEventListener('error', (event) => {
        console.error(`error recording stream: ${event.error.name}`)
    });
    recorder.start();
}
record();
					

The same, but using the onerror event handler property:

async function record() {
    const stream = await navigator.mediaDevices.getUserMedia({audio: true});
    const recorder = new MediaRecorder(stream);
    recorder.onerror = (event) => {
        console.error(`error recording stream: ${event.error.name}`)
    };
    recorder.start();
}
record();
