Im trying to dynamically create a CSV file using javascript that the user can download. This only has to work in IE.

The html the javascript generates looks something like this

 <a href="data:application/octet-stream,field1%2Cfield2%0Afoo%2Cbar%0Agoo%2Cgai%0A">CSV</a>

Which seams to work fine in chrome but IE10 just breaks.

Is there a better way to dynamically create a file using JavaScript and then give the user a link to download it? I cant use PHP as the entire system needs to run on the client-side due to restrictions placed by the user. The system all needs to work on a touch screen (with no right click option) so the link needs to give the user the ability to download, not open the file.

Internet Explorer 10 doesn't support the data protocol on the a element. Per the documentation, the only supported elements/attributes are the following:

  • object (images only)
  • img
  • input type=image
  • link
  • CSS declarations that accept a URL, such as background, backgroundImage, and so on.

You should know that what you're attempting to do smells like a phishing attempt; for this reason you shouldn't expect browsers to support this pattern. You can read more about data-uri phishing in the paper Phishing by data URI.

I had the same problem, I download the data uri in this way with Chrome:

var link = document.createElement("a");
link.download = dataItem.Filename;
link.href = data;
link.click();

But it does not work in Internet Explorer. I have found a library that works in Internet Explorer, https://github.com/rndme/download

The only issue for me is the dowload of files with longer MIME type like odt, docx, etc. For all the other kind of files it look great!
