I'm quite new to GAS & JS so please bear with me.

Problem 1 solved by @Cooper

I'm trying to pass the pdf link that gets generated by pdf.gs to an href in PDFlinkHTML.html.

I initially just had a Html output in the generatePDF() function and used href:"${pdf.getURl()}" but this is not viable anymore since the htmlService uses a lot of CSS, jQuery and needs a separate File.

Problem 2

I also have a loading spinner (essentially just a fixed div) in my htmlService which i want to hide (with either pure JS or jQuery) as soon as the PDF is generated and the link has been passed on to the href.

(My current "workaround" is just displaying the loading spinner in a separate ModalDialog at the start of the function & the PDFlinkHTML.html the at the end. Looks fine but feels cheap.)

I'd really appreciate some help & input.

Regards

How about something like this:

var temp = HtmlService.createTemplateFromFile('PDFlinkHTML')
temp.pdflink = pdflinkData;
var html = temp.evaluate().setWidth(400).setHeight(250);
ui.showModalDialog(html, "‎");

 href= <?= pdflink ?>
