I'm trying to download a file using HTML a tag

 var a = document.createElement("a");
 a.href = "floor.laz";
 a.click();

I get this error:

After the browser started the download. Is there anyway to know from the code when an error like this happens?

Normal

In Chrome by pressing F12 you can get to DevTools and errors are listed in Console tab – IiroP May 09 '17 at 15:00
have a reporter on the server. Which checks if the whole file is downloaded. The trigger for checking can be sent when the user clicks on the link. – warcops May 09 '17 at 15:01
Why use a link when you can use ajax and catch every error possible? – Bast May 09 '17 at 15:02
I would think you can use the HTTP server response code. And like @Bast advices is to use Ajax. http://stackoverflow.com/questions/22987349/is-there-a-way-to-get-http-status-code-name-using-js-and-angularjs – Daniel May 09 '17 at 15:06
