But I don't think we should actually set the FileList object itself; seems dangerous to have the object identity change... cc'ing Boris who may have relevant opinions on API design around this. 90773 2 ian 2013-07-15 23:57:59 +0000 Space here may be constrained by implementations: https://bugs.webkit.org/show_bug.cgi?id=87154 https://bugzilla.mozilla.org/show_bug.cgi?id=757664 90780 3 bzbarsky 2013-07-16 01:35:43 +0000 In the thread starting http://lists.w3.org/Archives/Public/public-script-coord/2013AprJun/0153.html most people felt that having setters and getters that return different types, and generally setters that do various magic things to what's being set, is pretty odd API... I don't know that I have a strong opinion myself, yet. 94269 4 ian 2013-10-03 20:14:22 +0000 So WebKit now does comment 1, with the object changing identity. Nothing in comment 0 has been implemented so far by anyone as far as I can tell. 94274 5 bzbarsky 2013-10-03 21:10:01 +0000 When you say "changing identity" do you mean that after I do: input.files = dataTransfer.files; then input.files === dataTransfer.files tests true? Or that it test false? 94325 6 ian 2013-10-04 19:49:20 +0000 It tests true. 94690 7 ian 2013-10-14 19:52:27 +0000 Spec-wise, I'm not sure how to proceed. I need two implementors intending on converging on the same thing or willing to implement the same proposal before I can update the spec. Moving back to "Needs Impl Interest" for now. 128758 8 annevk 2017-07-21 11:07:52 +0000 Please file a new issue at https://github.com/whatwg/html/issues/new if this is still desired. 128776 9 tkent 2017-07-24 03:22:21 +0000 (In reply to Anne from comment #8) > Please file a new issue at https://github.com/whatwg/html/issues/new if this > is still desired.
