onTouchStart fire extremely slow in ios9.2'safari #5817
Comments
Can you provide two jsfiddles? One to demonstrate that it is fast without React, and another to demonstrate that it is slow in React? |
No response for two weeks. We can re-examine this issue if OP can demo the problem. |
sorry,so busy these days. i will provide jsfiddles as soon as possible, . i could simply describe the test method.just a really easy example, like these below,
this alert will show very slow after i touch [div] element on screen on ios9.2'safari , but,other browser like chrome perform normally. |
@jimfb could this issue be reopened base on the comment above? |
@biblesyme are you experiencing the same with the latest 15.0.1 version? |
The example above doesn’t demonstrate that the lag doesn’t exist without React. |
reactExample(https://jsfiddle.net/69z2wepo/39302/) it seems as a safari problem, but, is anybody could explain why it's so slow to trigger a touchstart on safari, and how to solve this problem |
hi guys,it's seems not because safari 'trigger' touchstart slow,but 'alert' slow. i don't know why. and, may i ask what's time React will support 'tap' event, it's seems not difficult to achieve this |
@biblesyme check this out: https://github.com/zilverline/react-tap-event-plugin#introduction We did not solved our problem using that plugin though, we ended up using https://github.com/ftlabs/fastclick |
