Downloading Files Using JavaScript/jQuery Without Replacing Current Page
Problem:
How do you initiate a file download manually in a separate tab or window, while avoiding the default behavior of replacing the current page with the downloaded file using JavaScript/jQuery?
Solution:
To download a file in a new tab or window without disrupting the current page:
Using an Invisible Iframe:
This method creates an invisible iframe and assigns the download URL to its src attribute:
<iframe>
This triggers the download in the background. To ensure that the browser downloads non-renderable files (e.g., HTML, text), the server must set the file's MIME type to a nonsensical value like application/x-please-download-me or application/octet-stream.
Opening in a New Tab (jQuery):
To open the file in a new tab, use jQuery to set the link's target attribute to _blank and specify the file's URL in the href attribute:
$('a#someID').attr({
target: '_blank',
href: 'http://localhost/directory/file.pdf'
});
When the link is clicked, the file will be downloaded in a new tab or window, depending on the browser's settings.
