HTML2Canvas使用总结

var copyDom = document.querySelector(‘#sxh‘);
      const width = copyDom.offsetWidth;
      const height = copyDom.offsetHeight;
      let scale = 4; // 设定倍数这样不会模糊
      html2canvas(copyDom, {
        width:width,
        heigth:height,
        windowHeight:height,
        windowWidth:width,
        scale:scale,
        scrollX:0,
        scrollY:0,
        y:0,
        useCORS: true,
        // allowTaint: true,
        // backgroundColor:"#2ab77d",
      }).then((canvas) => {
        var url = canvas.toDataURL("image/png", 1.0).replace("image/png","image/octet-stream");//图片地址
