71113 2011-10-28 05:50:45 -0700 [V8] Event.type incorrectly reports that it is writable 2011-11-01 16:08:13 -0700 1 1 1 Unclassified WebKit WebCore JavaScript 528+ (Nightly build) Unspecified Unspecified RESOLVED DUPLICATE 48337 P2 Normal --- 1 raynos2 webkit-unassigned ap arv dominicc oldest_to_newest 492402 0 raynos2 2011-10-28 05:50:45 -0700 var e = document.createEvent("UIEvent"); var pd = Object.getOwnPropertyDescriptor(e, "type"); console.log(pd.writable); // type is writable e.type = "foobar"; console.log(e.type === ""); // Webkit Y U DO THIS. test : http://jsfiddle.net/WxA3a/1/ in chrome 14. I presume this is an issue with `e.type` living in C++ land and `e.type = "foobar"` living in ES land. As a sidenote delete e.type; e.type = "click"; breaks e.initEvent() 492590 1 ap 2011-10-28 12:19:36 -0700 I cannot reproduce this with Safari 5.1 or with a current local build. The value of pd.writable is false, like it should be per <http://www.w3.org/TR/DOM-Level-3-Events/#webidl-events-Event>: readonly attribute DOMString type; 492603 2 arv 2011-10-28 12:30:24 -0700 Yeah, this is wrong in Chromium/V8. But, type is specced as a getter on Event.prototype 492607 3 raynos2 2011-10-28 12:34:26 -0700 Given that the value is different in Safari 5.1 and Chrome (14/15). Is this still an issue with Webkit or an issue with v8/chromium? Should I go complain to v8 or chromium instead? 494259 4 dominicc 2011-11-01 16:08:13 -0700 *** This bug has been marked as a duplicate of bug 48337 ***
