Why two requests when I download a file? [closed]

Answer 1

I do not see anything wrong with your code. I replicated your code and tried to reproduce the issue which you are facing. But I am not able to repro in Chrome, IE and Firefox.

It looks like this issue is specific to FireFox browser of yours and due to some plugin/Extension. Disable all the plugins in the browser and give it a try, it should work.

Answer 2

You are missing with e.preventDefault() in your script. What is happening here is your action is hit by both script and normal post. So if you put e.preventDefault() like below, then it will prevent browser's default postback and only javascript's code will execute your request.

$("#myForm").on("submit", function(e) {
  e.preventDefault();
  window.location.href = $(this).attr("action");
});
