Posted from: 98.110.194.132 User agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:40.0) Gecko/20100101 Firefox/40.0 119177 1 bzbarsky 2015-04-01 13:28:38 +0000 Window has three different things appearing on it (or more precisely on the named properties object) as named properties: 1) Frame names. 2) Element ids. 3) Element names for some elements. Right now the spec says these should all be enumerable. UA behavior seems to be the following: Chrome: none are enumerable. Safari: none are enumerable. IE: Only frame names are enumerable, others are not. Firefox: Frame names, element names, and _some_ element IDs are enumerable (long story in terms of why it ends up this way). I think we should standarize on either the Chrome/Safari behavior or the IE behavior here, personally. 119178 2 1591 bzbarsky 2015-04-01 13:29:15 +0000 Created attachment 1591 Small testcase for this 119180 3 bzbarsky 2015-04-01 13:42:17 +0000 I just checked, and Firefox used to do what Chrome/Safari do before we started trying to align with the current spec. Presto Opera used to do what IE does. I'm going to switch Firefox to our old behavior for now until this is sorted out for iframes. 119189 4 zcorpan 2015-04-02 08:58:57 +0000 Adrian, are you OK with changing this in IE/Spartan to not enumerate frame names? 119236 5 adrianba 2015-04-04 17:24:14 +0000 (In reply to Simon Pieters from comment #4) > Adrian, are you OK with changing this in IE/Spartan to not enumerate frame > names? I checked with Travis on this (cc'd). Given that there's no interop here we'd be okay with changing to the Chrome/Safari behaviour and not enumerating names (with the usual caveat of not knowing when we'd check in this change - it actually turns out to be a reasonable amount of work to remove). 122971 6 annevk 2015-09-01 12:53:05 +0000 https://github.com/whatwg/html/commit/681f341183cd8e029028f1862c147b25f5e51916 Thank you bz for doing this research. 123002 7 travil 2015-09-01 19:24:42 +0000 Note to self: I filed a bug to track this in Edge (internal VSO4445842). 1591 2015-04-01 13:29:15 +0000 2015-04-01 13:29:15 +0000 Small testcase for this test.html text/html 1217 bzbarsky PCFET0NUWVBFIGh0bWw+CjxodG1sPgogICAgPGhlYWQ+CiAgICAgICAgPHNjcmlwdD4KICAgICAg ICAgICAgdmFyIG9uTG9hZCA9IGZ1bmN0aW9uICgpIHsKICAgICAgICAgICAgICAgIGNvbnNvbGUu bG9nKCJESVYgOiAiICsgKCdib3gxJyBpbiB3aW5kb3cpKQogICAgICAgICAgICAgICAgY29uc29s ZS5sb2coIklNRyA6ICIgKyAoJ2JveDInIGluIHdpbmRvdykpCiAgICAgICAgICAgICAgICBjb25z b2xlLmxvZygiSUZSQU1FIDogIiArICgnYm94MycgaW4gd2luZG93KSkKICAgICAgICAgICAgICAg IGNvbnNvbGUubG9nKCJJTUcyIDogIiArICgnYm94NCcgaW4gd2luZG93KSkKICAgICAgICAgICAg ICAgIAogICAgICAgICAgICAgICAgdmFyIGhhc0JveDEgPSBmYWxzZQogICAgICAgICAgICAgICAg dmFyIGhhc0JveDIgPSBmYWxzZQogICAgICAgICAgICAgICAgdmFyIGhhc0JveDMgPSBmYWxzZQog ICAgICAgICAgICAgICAgdmFyIGhhc0JveDQgPSBmYWxzZQogICAgICAgICAgICAgICAgCiAgICAg ICAgICAgICAgICBmb3IgKHZhciBpIGluIHdpbmRvdykgewogICAgICAgICAgICAgICAgICAgIGlm IChpID09ICdib3gxJykgaGFzQm94MSA9IHRydWUKICAgICAgICAgICAgICAgICAgICBpZiAoaSA9 PSAnYm94MicpIGhhc0JveDIgPSB0cnVlCiAgICAgICAgICAgICAgICAgICAgaWYgKGkgPT0gJ2Jv eDMnKSBoYXNCb3gzID0gdHJ1ZQogICAgICAgICAgICAgICAgICAgIGlmIChpID09ICdib3g0Jykg aGFzQm94NCA9IHRydWUKICAgICAgICAgICAgICAgIH0KICAgICAgICAgICAgICAgICAgICAKICAg ICAgICAgICAgICAgIGNvbnNvbGUubG9nKCJoYXMgRElWICIgKyBoYXNCb3gxKQogICAgICAgICAg ICAgICAgY29uc29sZS5sb2coImhhcyBJTUcgIiArIGhhc0JveDIpCiAgICAgICAgICAgICAgICBj b25zb2xlLmxvZygiaGFzIElGUkFNRSAiICsgaGFzQm94MykKICAgICAgICAgICAgICAgIGNvbnNv bGUubG9nKCJoYXMgSU1HMiAiICsgaGFzQm94NCkKICAgICAgICAgICAgfQogICAgICAgIDwvc2Ny aXB0PgogICAgPC9oZWFkPgogICAgPGJvZHkgb25sb2FkPSJvbkxvYWQoKSI+CiAgICAgICAgPGRp diBpZD0iYm94MSI+PC9kaXY+CiAgICAgICAgPGltZyBpZD0iYm94MiIvPgogICAgICAgIDxpZnJh bWUgbmFtZT0iYm94MyI+PC9pZnJhbWU+CiAgICAgICAgPGltZyBuYW1lPSJib3g0Ij48L2ltZz4K ICAgIDwvYm9keT4KPC9odG1sPgo=
