Remove data from form Data in java script

Question

How can I remove appended data from form Data in Java script? I am using form data for uploading file and passing it to the handler. Code:

var formData = new FormData();
var uploadfiles = $("#ImagesUpload").get(0);
var uploadedfiles = uploadfiles.files;

for (var i = 0; i < uploadedfiles.length; i++)
{
   formData.append('file', uploadedfiles[i]); 
}

@vivek_singh The answer in the duplicate says that this is not possible. You have to simply not append date that you do not want to include in the FormData. — Peter Olson, May 16 '14 at 15:34

You can't remove data you've appended to a FormData object. There is nothing exposed in the API to allow this. Just create a new FormData.

No, you cannot clear data in a FormData object. You'll have to recreate it. – Ray Nicholus May 19 '14 at 10:45

var formData = new FormaData(); – norbertas.gaulia Sep 29 '17 at 16:06
formData.delete(key); https://developer.mozilla.org/en-US/docs/Web/API/FormData/delete – Chintan Mathukiya Nov 14 '18 at 11:24
creating new FormData on every form submit is very important while sending data to server – Mithun Kumar Oct 27 '21 at 14:39
