Jquery delete value from FormData object

Question

how I can delete value from FormData object with same name? I have HTML form with two input files.

Answer 1

Manipulate the array of files and re-add the elements minus the one needed to be removed.

var files = formData.getAll("file[]");
files.splice($("[type='file']").index($("#animal")), 1);
formData.delete("file[]");
$.each(files, function(i, v) {
    formData.append("file[]", v);
});
