----------------------------
Summary: call animation.transition in mounted hook immediately
cause problems
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: Adam Feng
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.
