jquery .submit() + disable input file

I have a form that is using .change() and .submit() to upload a photo as soon as a user selects one. I'm now trying to implement a disabled on the input file after the submit() has started to avoid multiple uploads at the same time.

HTML:

  <form action="includes/photos.php" id="joinPhotoUploadForm" enctype="multipart/form-data">
    <input type="file" name="file" id="file"><br>
  </form>

JQUERY:

$('input#file').change(function() {
    $('form#joinPhotoUploadForm').submit();
    $('input#file').prop('disabled', true);     // Prevent Multiple Files Uploads
  }
});

The catch is under IE only the input#file is disabled before the .submit() starts on the second upload onwards.

Is there a way to prevent the disabled from occuring until the .submit() has started?

Is there another way to achieve this? something else I could disable? Could I unbind the .change()? Note: the disable is enabled later (after ajax return successfully).

thankyou

You need to prevent the form from submitting again if the file input is disabled. the second eventListener will do that for you.

$('input#file').change(function() {
    $('form#joinPhotoUploadForm').submit();
    $('input#file').prop('disabled', true);     // Disable to Prevent Multiple Files Uploads
});

$("#joinPhotoUploadForm").submit(function(e) {
  if ($(this).find("#file").is(":disabled")) {
    e.preventDefault();
  }
});

I like doing like this: $('#myform').trigger( 'reset' );
