How do I change a filename on-download with javascript?

Question

The script adds a download link for videos (on a specific site). How do I change the filename to something else while downloading?

Example URL:
\"http://websit         


        

Answer 1

The filename for downloading is set in the header (take a look at "Content-Disposition"), wich is created on server-side.

There's no way you could change that with pure javascript on a file you're linking to unless you have access to the server-side (that way you could pass an additional parameter giving the filename and change the server-side behaviour to set the header to match that... but that would also be possible with pure html, no need for javascript). Conclusion: Javascript is absolute useless to achive what you want.
