          let PDF = new JSPDF('', 'pt', 'a4')

          if (leftHeight < pageHeight) {
            PDF.addImage(pageData, 'JPEG', 0, 0, imgWidth, imgHeight)
          } else {
            while (leftHeight > 0) {
              PDF.addImage(pageData, 'JPEG', 0, position, imgWidth, imgHeight)
              leftHeight -= pageHeight
              position -= 841.89
              if (leftHeight > 0) {
                PDF.addPage()
              }
            }
          }
          PDF.save('123.pdf')
        }
      })
      html2canvas()
    }
  },
  mounted () {
    this.$nextTick(() => {
      window.addEventListener('resize', () => {
        this.getPdf()
      })
    })
  }
}
