js把网页截屏

// 引入html2canvas库
import html2canvas from 'html2canvas';

// 要截取的元素
const element = document.getElementById('target-element');

html2canvas(element).then(canvas => {
  // 将canvas转换为图片
  const imgData = canvas.toDataURL('image/png');
  // 创建一个a标签用于下载图片
  const link = document.createElement('a');
  link.href = imgData;
  link.download = 'screenshot.png';
  link.click();
});

html2canvas(document.body, {
  scrollX: -window.scrollX,
  scrollY: -window.scrollY
}).then(canvas => {
  const imgData = canvas.toDataURL('image/png');
  // 处理生成的图片数据，例如下载或展示
});
