Uncaught (in promise) TypeError: video.addEventListner is not a function

Question

我正在尝试访问我的笔记本电脑的音频和视频，并试图在屏幕上检索摄像头视频，在完成以下所有操作后，它只是访问我的摄像头和麦克风，但没有在屏幕上显示我的照片（只是黑屏）。在控制台显示此错误- “script.js:16 Uncaught (in promise) TypeError: video.addEventListner 不是一个函数在 addVideoStream (script.js:16) 在 script.js:11"

下面是我的脚本，html，css代码请帮忙-

const videoGrid=document.getElementById('video-grid');
const myVideo=document.createElement('video');
myVideo.muted=true;

let myVideoStream
navigator.mediaDevices.getUserMedia({
    video:true,
    audio:true
}).then(stream=>{
    myVideoStream=stream;
    addVideoStream(myVideo,stream);
})

const addVideoStream=(video,stream)=>{
    video.srcObject=stream;
    video.addEventListner('loadedmetadata',()=>{
        video.play();
    })
    videoGrid.append(video);
}

#video-grid{
    display:flex;
    justify-content:center;
}

video{
    height:300px;
    width:400px;
}

您的语法有错别字。试试这个。

video.addEventListener.

Listener

缺少 e

Uncaught (in promise) TypeError: video.addEventListner is not a function

Uncaught (in promise) TypeError: video.addEventListner is not a function

video-streaming

node.js
