Frame has 2 behaviors: frame as document element (like div or another DOM element) and frame as window element (like global window object). So if you want to remove iframe from DOM tree you have to work with iframe like with DOM element

function remove(){
 var frame = document.getElementById("upload_iframe");
 frame.parentNode.removeChild(frame);
}
