javascript - chrome.downloads.download ignores saveAs option and opens the dialog regardless - Stack Overflow

I'm trying to create an extension which downloads multiple files at once.

In order to acplish that, I'm using chrome downloads api, here is the code (with AngularJS):

var fileDownloadProperties = function(raw) {
    return {
      url: "https:" + raw.url,
      filename: sharedDir + "/" + raw.name + "pdf",
      saveAs: false
    }
};
$scope.status = "";
filesToDownload.forEach(function (raw) {
  chrome.downloads.download(fileDownloadProperties(raw));
});

The problem is that when the script runs it ignores the saveAs option, and proceed with opening the save as dialog (the name and location are passed correctly, as they are the defaults in the dialog, but could be overwritten).

While it does allow me to download, it's not very useful as I can have over tens of files (and the next save dialog will open only when the previous file finished downloading!).

Is there a way to force chrome to download files silently and simultaneously? I tried other solutions (like the code below), but none seems to avoid the dialog from opening.

var a = document.createElement("a");
a.href = files[0];
a.download = files[0];
a.click();  

Any help will be greatly appreciated, thanks.

• 1 I don't believe it's possible. I certainly wouldn't use Chrome again if I found it had downloaded files in an unsolicited manner, even more so if it did it silently. Can you not create a zip file on the server and download that instead? At least it's only 1 download. – Reinstate Monica Cellio Commented Dec 30, 2016 at 17:18
• @Archer So what is the purpose of the saveAs option? It is stated in docs that if set, the saveAs will "Use a file-chooser to allow the user to select a filename". – Nadav96 Commented Dec 30, 2016 at 17:23
• From the documentation it sounds like saveAs is the opposite of what you want. What happens if you just supply a filename? – Reinstate Monica Cellio Commented Dec 30, 2016 at 17:29
• @Archer unfortunately it still opens the dialog... And I didn't meant pletely silent, rather that the files will download without opening the dialog every time (and saved to the Downloads folder), it must be possible, seems to me like a basic functionality. – Nadav96 Commented Dec 30, 2016 at 17:33
• Okay - that makes more sense. Can you possible consider making a zip file on the server, upon request of several files? – Reinstate Monica Cellio Commented Dec 30, 2016 at 17:35

You can instruct your user to set Chrome settings to have

Ask where to save each file before downloading

"Save As" turned on/off.

The answer provided by Jenna is an acceptable workaround, however, forcing users to change their preferences is not something I will take as an "Accepted solution". There is an issue filed for this bug on this thread.

I guess the only possible way of having a correct fix is for the chrome team to stand up and fix this issue for us developers. I would remend to put more pressure on the thread by adding a ment indicating why you need this to be fixed and how urgent it is. Also and most important, make sure you click the star to have the issues starred as they will pay more attention to it.
