http://www.w3.org/Bugs/Public/show_bug.cgi?id=12248 --- Comment #30 from Allen Wirfs-Brock <allen@wirfs-brock.com> 2011-03-16 02:47:38 UTC --- (In reply to comment #29) What do you mean by "isn't possible currently with interfaces-implemented-by-JS"? In JavaScript, this is a property existence test that can be performed using Object.prototype.hasOwnProperty or Object.getOwnProperty. This exact pattern is used quite extensively by the ES5 Object.defineProperty to process its "options parameter". Are you saying that host object interfacing layers in browser don't provide the capability for such tests or is something else the issue? -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
