After the image load event fires event.target contains a IMG element When the promise is resolved event.target is null It can be worked around by resolving the promise with event.target rather than event Here is a demonstration http://jsfiddle.net/8ys0dn4x/1/ Fails in Safari and webkit nightly In Firefox the code works as expected In Chrome there is also a bug, however it is slightly different in that the last promise to resolve in a group still remembers the target, but others are null Here is a variation on the demonstration http://jsfiddle.net/d13sf3f2/5/ 1079211 1 bbirch 2015-03-22 19:41:54 -0700 Minimal test case (new Promise( function( resolve ) { var i = document.createElement("IMG"); i.onload = function( event ) { console.log("onload", event.target ); // -> <img ...> resolve(event); }; i.src = "http://i.imgur.com/waV028T.jpg"; })).then( function( resolved_event ) { console.log( resolved_event.target ); // -> null }); 1503296 2 lforschler 2019-02-06 09:19:02 -0800 Mass move bugs into the DOM component. 2036748 3 ahmad.saleem792 2024-05-21 09:30:29 -0700 It seems to work for me and matching with Chrome Canary 127. Test case from Comment 0 shows two console message across all browsers (Safari 17.5 , Chrome Canary 127 and Firefox Nightly 128).
