Download pdf without opening in browser

Question

I want to download pdf file directly without viewing, i have tries following things till now but nothing is helping.

1- window.open("https://s3-link1.pdf", 'Download');

2- <a href="https://s3-link1.pdf" download>Link</a>

Link - https://s3-link1.pdf

Assume my domain is https://www.somedomain.com

I somewhere read we can't download cross-origin files. content-disposition header is required to be passed from backend. I am puzzled here. Another csv file of cross-origin is being downloaded easily.

https://s3-link2.csv

I just need to download pdf file using javascript. Please guide me.

Answer 1

Try with fetch.

fetch("https://s3-link1.pdf", {
    method: 'GET'
}).then(resp => resp.blob())
    .then(blob => {
        const url = window.URL.createObjectURL(blob);
        const a = document.createElement('a');
        a.style.display = 'none';
        a.href = url;
        a.download = "name"; // the filename you want
        document.body.appendChild(a);
        a.click();
        window.URL.revokeObjectURL(url);
    })

Answer 2

Option 1: with jQuery you can try this:

$.get("https://s3-link1.pdf", function (result)
{
    var blob = new Blob([result]);
    var link = document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    link.download = "myFileName.pdf";
    link.click();
});

Option 2: The download attribute works in all modern browsers, including MS Edge, but not Internet Explorer.

In the latest versions of Chrome, you cannot download cross-origin files (they have to be hosted on the same domain).

<a href="https://s3-link1.pdf" download>Download PDF</a>
