Controlling Blob URL's

[joeedh]

Hi. I have several HTML5 apps I work on, all of which allow users to save files locally. I can't seem to figure out how to control the URL so the users aren't downloading files with gibberish names, or how to force the browser to open a Save As dialog.

Anyway, any help would be greatly appreciated.

Have you tried using <a download>?

(Note that <a download> doesn't work in Safari; see http://wkbug.com/102914)

re: controlling the name: as @annevk states, <a download> is for.
re: "Save As" dialog - that's a user agent option as to whether to show UI or automatically place the file in a dedicated Downloads folder.

I can imagine a feature request for e.g. File.saveAs(optional filename) but I wouldn't do that by controlling the URL.
