> Key: WEEX-346
> URL: https://issues.apache.org/jira/browse/WEEX-346
> Project: Weex
> Issue Type: Bug
> Environment: weex SDK 0.18.0, jsfm 0.24.4, on iOS 11.2 iphon10,3
> Reporter: Danz He
> Assignee: qz
> Priority: Major
>
> demo: [http://dotwe.org/vue/eaf53504400d435144527a36053f9a7e]
> *How to reproduce error*: scroll the list to the middle (near bottom), a
> message toast should show in page and only show once. And after that, the
> message will fade out by the call of animation.transition. It probably act
> normal in the first time, but reenter the page it may fail.
> *Preliminary investigation*: It may caused by the immediate call in the
> mounted hook, which are guaranteed to be called exactly once when scrolling
> to the middle of the page. Somehow the animation.transition call influenced
> the styles immediately without a transition animation. But when I put it in a
> timer, and execute it with 0 latency (which will still be triggered in the
> next loop cycle, not immediately), then it works well.
