Как сохранить этот PDF и, если это возможно, я могу конвертировать или сделать это в текстовый документ?

По существу я хочу данные URI, так что я могу использовать его с FileSaver.js скачать, но я не могу понять, где URI находится в pdfmake.js file.

Answer 1

Прежде всего вам нужно сделать BLOB из base64, а затем передать его как url ​​на якорь. Для того, чтобы конвертировать base64 в Blob посмотрите здесь:

Creating a Blob from a base64 string in JavaScript

затем создать URL из сгустка:

blobUrl = window.URL.createObjectURL(Blob); 

и добавить ссылку для скачивания:

<a href="'+ blobUrl +'" download="filename.pdf"> 

Answer 2

Я рекомендую вам использовать https://github.com/MrRio/jsPDF для создания PDF. Вот пример: https://parall.ax/products/jspdf

Для MS Word попробуйте https://github.com/MrRio/DOCX.js. Но я не думаю, что вы можете конвертировать base64 в docx
