Input event on file type not firing in Safari browser

Question

I am uploading a file using AJAX and jQuery. It is working well in Chrome and Firefox but the problem I am getting is in Safari. I tried to debug this but the debugger did not stop when I upload the file.

<input type="file" class="file_input" name="myfile"/>

$(document).on('input', '.file_input', function() {
  var that = $(this);
  var formData = new FormData();
  formData.append("userfile", this.files[0]);
  showLoader();

  $.ajax({
    cache: false,
    headers: {
      'X-CSRF-Token': _token
    },
    url: base_url + "controller/action",
    type: 'POST',
    data: formData,
    contentType: false,
    processData: false,
    success: function(data) {
      that.closest('tr').find('.document').empty();
      hideLoader();
    }
  });
});

Safari does not support the input event on file input elements:

(Safari and some other browsers) don't fire an input event when (un)checking a checkbox or radio button, or when changing the selected file(s) of an . See Chrome bug, WebKit bug, and Firefox bug

To fix this you can use the more widely supported change event instead:

$(document).on('change', '.file_input', function() {
  // your code...
});

- 2020 Update -

This issue in Safari was fixed in version 13.1, released in March 2020. To be clear, any version of Safari since then now supports the input event on a file input.

If you have a requirement to support legacy versions of Safari, then you will still need to use the change event, as outlined in my original answer above.
