download csv file from web api in angular js

my API controller is returning a csv file as seen below:

    [HttpPost]
    public HttpResponseMessage GenerateCSV(FieldParameters fieldParams)
    {
        var output = new byte[] { };
        if (fieldParams!= null)
        {
            using (var stream = new MemoryStream())
            {
                this.SerializeSetting(fieldParams, stream);
                stream.Flush();
                output = stream.ToArray();
            }
        }
        var result = new HttpResponseMessage(HttpStatusCode.OK) { Content = new ByteArrayContent(output) };
        result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
        result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
        {
            FileName = "File.csv"
        };
        return result;
    }

and my angularjs that will send and receive the csv file is shown below:

$scope.save = function () {
            var csvInput= extractDetails();

            // File is an angular resource. We call its save method here which
            // accesses the api above which should return the content of csv
            File.save(csvInput, function (content) {
                var dataUrl = 'data:text/csv;utf-8,' + encodeURI(content);
                var hiddenElement = document.createElement('a');
                hiddenElement.setAttribute('href', dataUrl);
                hiddenElement.click();
            });
        };

In chrome, it downloads a file which is called document but has no file type extension. The content of the file is [Object object].

In IE10, nothing is downloaded.

What could i do to fix this?

UPDATE: This might work for you guys out there with the same problem: link

Try it like :

File.save(csvInput, function (content) {
    var hiddenElement = document.createElement('a');

    hiddenElement.href = 'data:attachment/csv,' + encodeURI(content);
    hiddenElement.target = '_blank';
    hiddenElement.download = 'myFile.csv';
    hiddenElement.click();
});

based on the most excellent answer in this question

I used the below solution and it worked for me.

 if (window.navigator.msSaveOrOpenBlob) {
   var blob = new Blob([decodeURIComponent(encodeURI(result.data))], {
     type: "text/csv;charset=utf-8;"
   });
   navigator.msSaveBlob(blob, 'filename.csv');
 } else {
   var a = document.createElement('a');
   a.href = 'data:attachment/csv;charset=utf-8,' + encodeURI(result.data);
   a.target = '_blank';
   a.download = 'filename.csv';
   document.body.appendChild(a);
   a.click();
 }

None of those worked for me in Chrome 42...

Instead my directive now uses this link function (base64 made it work):

  link: function(scope, element, attrs) {
    var downloadFile = function downloadFile() {
      var filename = scope.getFilename();
      var link = angular.element('<a/>');
      link.attr({
        href: 'data:attachment/csv;base64,' + encodeURI($window.btoa(scope.csv)),
        target: '_blank',
        download: filename
      })[0].click();
      $timeout(function(){
        link.remove();
      }, 50);
    };

    element.bind('click', function(e) {
      scope.buildCSV().then(function(csv) {
        downloadFile();
      });
      scope.$apply();
    });
  }

The last answer worked for me for a few months, then stopped recognizing the filename, as adeneo commented ...

@Scott's answer here is working for me:
