Uncaught TypeError: Невозможно прочитать свойство 'name' из undefined в tableToJson

1 голос
/ 25 марта 2020

У меня есть файл шаблона, который я пытаюсь преобразовать в PDF. Немного погуглив, я нашел фреймворк под названием JSPDf. Когда я пытаюсь использовать его, он выдает ошибку Uncaught TypeError: Невозможно прочитать свойство 'name' из неопределенного jspdf.

у нас есть две кнопки 1-> printDiv, эта работает нормально. 2-> saveDiv эта кнопка, имеющая проблему. Когда мы нажимаем эту кнопку, чтобы загрузить PDF, я получаю ошибку консоли, такую ​​как Uncaught TypeError: Cannot read property 'name' of undefined at tableToJson(jspdf.debug.js).

Вот мой код, я помещаю весь код в один файл.

index. html

 var doc = new jsPDF();

 function saveDiv(divId, title) {
 doc.fromHTML(`<html><head><title>${title}</title></head><body>` + document.getElementById(divId).innerHTML + `</body></html>`);
 doc.save('div.pdf');
}

function printDiv(divId,
  title) {

  let mywindow = window.open('', 'PRINT', 'height=650,width=900,top=100,left=150');

  mywindow.document.write(`<html><head><title>${title}</title>`);
  mywindow.document.write('</head><body >');
  mywindow.document.write(document.getElementById(divId).innerHTML);
  mywindow.document.write('</body></html>');

  mywindow.document.close(); // necessary for IE >= 10
  mywindow.focus(); // necessary for IE >= 10*/

  mywindow.print();
  mywindow.close();

  return true;
}
