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. |

I think we need more information about what the OP is doing.
- Where does the BLOB come from? If it's from a database, maybe it's simplest to convert it to a base64 data URI on the server side, and then use that for the download. - How and where is a SVG generated, and where is it used? The OP haven't shown any code example of that. |

I read that a blob URL references an object that is in the browser's memory and not a physical file. Beats me how it, in this case, got into the memory to start with.
