"If event was canceled, then the error is handled. Otherwise, the error is not handled." http://software.hixie.ch/utilities/js/live-dom-viewer/saved/3319 http://software.hixie.ch/utilities/js/live-dom-viewer/saved/3320 I think "return false" means the event is canceled, but at least Blink/WebKit/Gecko report the error to the console. (And do not report to the console for "return true".)

I didn't find that when looking for it. :-) Could you add a note about this in step 15 of https://html.spec.whatwg.org/multipage/webappapis.html#runtime-script-errors ? 115850 3 ian 2014-12-03 19:54:15 +0000 Yeah, good idea. 125217 4 richarupela95 2016-02-23 08:24:22 +0000 "return true is canceled for "error" events, hence do not report error to console." is this fine? 125218 5 annevk 2016-02-23 09:14:34 +0000 I think it would be better to reference the "the event handler processing algorithm" directly using <span data-x=""> in the note. I.e., <p class="note">Returning true cancels <var>event</var> per <span data-x="...">the event handler ...</span>.</p> 125243 6 annevk 2016-02-23 17:49:10 +0000 https://github.com/whatwg/html/pull/725
