Use below code will help you

function clearFileUpload(id){
    // get the file upload element
    fileField     = document.getElementById(id);
    // get the file upload parent element
    parentNod     = fileField.parentNode;
    // create new element
    tmpForm        = document.createElement("form");
    parentNod.replaceChild(tmpForm,fileField);
    tmpForm.appendChild(fileField);
    tmpForm.reset();
    parentNod.replaceChild(fileField,tmpForm);
}
