[Ticket cloned from T10307: How attachments are exported onto PDF]
Hi Serge, apologies for re-opening quite an old ticket. I've added a question type of 'file' to an example on SurveyJs and I've uploaded a very simple word document. This adds a link to the exported PDF just fine. However, when I come to click on the link, the attachment doesn't download. I have to instead right-click, and open the link in a new tab in order for the attachment to successfully download. Is this normal behavior?
Hello Mo,
It seems PDF file attachments were never meant to be downloaded by clicking a link. When exporting a survey to PDF, we Base64 encode a file and produce a link tag in the resulting PDF file using the jsPDF library.
To save an embedded file to your computer, simply right-click the attachment link, select "Save link as…" and proceed with saving a file.
Please let us know if you have any questions.
Hello Mo,
Unfortunately, it seems no. In the LinkBrick.renderInteractive method, we use the jsPDF doc.textWithLink method to generate a link. The this.link parameter which is used there is simply a Base64 encoded document. That is, when a user click a link, this doesn't basically trigger a browser download file action.
Hope this clarifies the situation. Drop me a line if anything remains unclear.
