Perfect, thanks. Do you happen to know if most servers will set the Content-Disposition to 'attachment' by default? There is no "most. Don't rely on it being set. This issue has been driving me ballistic, and this was the only option that worked and is supported by IE.
No jquery. This doest work if you're trying to download an image, it would open the image in the browser — Dheeraj. Danubian Sailor Danubian Sailor It does, at least if you actually apprnf the iframe to document. This doesn't seem to be working in Chrome right now, although it used to work. I wonder if it kind of intermittently stops working in different versions of Chrome. Works in Chrome as of Version Does not work with images in Firefox v It just renders the image in the iframe.
This will fail silently if the file is of a type the browser knows how to render itself, though unless the server returns a Content-Disposition header indicating the file should be downloaded. The question is explicitly asking how to do this with a button instead of a link.

However, Button 1 would download the file for file types that it couldn't open itself for example,. Button 2 downloaded the text file. However, Button 2 only downloaded the file if the path was relative.
When I changed the path to an absolute path, then the browser opened it in a new tab. I tested this on Firefox, Safari, and Chrome.

It simply causes the browser to navigate to the target URL. Whether that results in the file at that URL being downloaded or being shown as a page in the browser depends upon the headers returned by the server when it serves the file and on what file types the browser is capable of rendering.

I installed Tampermonkey, navigated to the page with the download link, and then clicked New Script under tampermonkey and added my javascript code. Now every time I navigate to the page in my browser, the file is downloaded. I then created a batch script that looks like this.
