我正在尝试在 HTML Canvas 中制作一个项目，但反复遇到此错误。我明白了 1) 当我使用
document.createElementcanvas.getContext<canvas id="canvas"></canvas>document.getElementByIdcanvas.getContextHTML<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Pythagoras Theorum Proof</title>
</head>
<body>
<canvas id="canvas"></canvas>
<script src="./script.js"></script>
</body>
</html>
JS/**
* @type {HTMLCanvasElement}
*/
const canvas = document.getElementById("canvas")
/**
* @type {CanvasRenderingContext2D}
*/
const ctx = canvas.getContext("2d")
(window.addEventListener("resize", () => {
canvas.width = window.innerWidth; canvas.width = window.innerHeight
}))()
canvas.style.border = "2px solid black"
（我需要 JSDoc 将
canvasHTMLCanvasElementctxCanvasRenderingContext2D我添加了几个分号，并且还确保
addEventListeneraddEventListenerundefined const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");
window.addEventListener("resize", () => {
canvas.width = window.innerWidth; canvas.width = window.innerHeight;
console.log("resized");
});
canvas.style.border = "2px solid black";<canvas id="canvas"></canvas>
