#Javascript download files from server how to
The only thing missing then is still the code on how to do this (download file from server to player via HTTP). Can you not work with server sockets on both sides, so that the server always accepts requests from player and vice versa. It is programmed not to require user interaction, as the only controller of the dedicated device is also the controller of the server. No, the device with the browser is not a client or customer machine, but a dedicated device to reproduce multimedia content. No browser will ever give your client-side scripts access to the file-system. Never going to happen.Ĭould you imagine what would happen if web-developers could simply save stuff on your computer without you agreeing to it or even being aware of it? No computer connected to the internet would survive for more than a day. If this option is omitted, the browser will show the file chooser or not based on the general user preference for this behavior (in Firefox this preference is labeled "Always ask you where to save files" in about:preferences, or in about:config).So you want your browser to download files and save them to the hard drive on your clients computer?

If the URL uses the HTTP or HTTPS protocols, an array of objects representing additional HTTP headers to send with the request. If omitted, this value will default to the filename already given to the download file, and a location immediately inside the downloads directory. Absolute paths, empty paths, path components that start and/or end with a dot (.), and paths containing back-references (. filename OptionalĪ string representing a file path relative to the default downloads directory - this provides the location where you want the file to be saved, and what filename you want to use. Use requires the "cookies" API permission. If omitted, the default cookie store is used. The cookie store ID of the contextual identity the download is associated with. conflictAction OptionalĪ string representing the action you want taken if there is a filename conflict, as defined in the downloads.FilenameConflictAction type (defaults to "uniquify" when it is not specified). However, if the download fails due to file-related, network-related, user-related, or other error, that error is reported.Ī string representing the post body of the request. true, the download continues when an HTTP error is encountered and the HTTP server error is not reported.false, the download is canceled when it encounters an HTTP error.Using this flag, for example, enables the download of server error pages.
