Hi all,
I've been wanting to get an export function to work on my site, which almost works perfectly, it just does not download automatically. Currently it generates this: <a target="_blank" download="MediumRandomNewick_treemap_outer.png" href="blob:http://localhost:8080/c02ebb93-19b9-43fa-872d-b32fc02dc56f">Export</a> But this is not clickable and also does not force the download, can anyone tell me how I would go about force downloading? Preferably with JavaScript. |

Seems the DOWNLOAD attribute at least works with data URIs like this:
CODE <a download="test.png" href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==">Example</a> (the above should generate an image file depicting a red dot). |
