Delete Function In Html Upload Form

I have simple upload form like this:

Solution 1:

It is not possible to delete a File object from read-only FileList object. You can add File objects to FormData object using .append(), then use .delete() to remove item from FormData() object by referencing the key in FormData; e.g.,

var data = new FormData();
for (var i = 0; i < files.length; i++) {
  data.append("file-" + i, files[i], files[i].name);
};
data.delete("file-0"); // delete `"file-0"` of `data`

then POST the FormData object to server.

You can alternatively add File objects to an Array and use .splice() to remove the item from the array, see input file to array javascript/jquery
