如何使用实习生js拍摄DOM元素的屏幕截图？

<canvas id="screenshotCanvas"></canvas>

// 获取需要截图的DOM元素
const element = document.getElementById('targetElement');

// 创建Canvas对象
const canvas = document.getElementById('screenshotCanvas');
const context = canvas.getContext('2d');

// 设置Canvas的宽高与DOM元素相同
canvas.width = element.offsetWidth;
canvas.height = element.offsetHeight;

// 绘制DOM元素到Canvas上
context.drawWindow(window, element.offsetLeft, element.offsetTop, element.offsetWidth, element.offsetHeight, 'rgb(255,255,255)');

// 将Canvas转换为图像数据URL
const dataURL = canvas.toDataURL();

// 在控制台输出数据URL
console.log(dataURL);
