這是一張圖片并且寬度和高度不是 0，但是當我在控制臺中打印它時，它返回 0。、這是我如何打印它的代碼：const video = document.getElementById("remoteVideo");video.addEventListener('play', () => { setInterval(async () => { console.log(video.width); console.log(video.height); }, 100) });這是完整的html：<!DOCTYPE html><html></html><head> <meta charset="UTF-8"> <title>Document</title> <style type="text/css"> html { height: 100%; } body { height: 100%; margin: 0; background: #111; text-align: center; } #remoteVideo { height: 70%; margin-top: 5%; background: #000; } #localVideo { width: 20%; position: absolute; right: 1.1em; bottom: 1em; border: 1px solid #333; background: #000; } #callButton { position: absolute; display: none; left: 50%; font-size: 2em; bottom: 5%; border-radius: 1em; } </style> <script defer src="static/face-api.min.js"></script></head><body> <video id="localVideo" autoplay muted></video> <video id="remoteVideo" autoplay></video> <button id="callButton" onclick="createOffer()">?</button> <script src="/socket.io/socket.io.js"></script> <script defer src="static/script.js"></script></body></html>我究竟做錯了什么？
為什么 video.width 是 0 但實際上是 539？
