Hello
I think this topic is same: Force download pdf on IOS
For this you have to use api.decorateCookedElement.
Something like this should work
Place it to the Header section to a component.
<script type="text/discourse-plugin" version="0.8.42">
api.decorateCookedElement(
element => {
const pdfFiles = element.querySelectorAll("a.attachment[href$='.pdf']");
if (!pdfFiles.length) {
return;
}
pdfFiles.forEach((pdf) => {
pdf.setAttribute("download", "");
});
},
{ id: "download-pdf", onlyStream: true }
);
</script>
I’ve tested it on my device and it works for me but if you want to use other attribute etc… you can easily change it… I hope it helps
