Summary: Adds a new event that fires when an animation is terminated without finishing normally (e.g. element is made display:none, animation-name property is updated etc.). This parallels the recently added transitioncancel event and allows authors to know that they should not keep waiting for an animationend event.
Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1302648 Link to standard: https://drafts.csswg.org/css-animations/#eventdef- animationevent-animationcancel Platform coverage: All platforms Estimated or target release: Firefox 54 Preference behind which this will be implemented: No pref DevTools bug: No special Devtools handling required. Do other browser engines implement this? No. Blink has a bug on file for implementing transitioncancel[1] which is marked "Hotlist-Interop" and we expect they will implement animationcancel at roughly same time. [1] https://bugs.chromium.org/p/chromium/issues/detail?id=642487 Tests: The working-in-progress patch include tests in web-platform-tests (testharness.js) format. However, we are still waiting for the CSSWG to merge their test repository into web-platform-tests before submitting them there. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
