Safari browser in the Chinese input method environment, the keydown event will be executed after the content changes, so I disable the default thing, that is, I cannot disable special character input?
under different browsers and input methods, the processing time and trigger ability of keydown and keypress are different.
Chrome:
1, Chinese input method all keys trigger, English input method all keys trigger;
Safari:
1. All keys of the Chinese input method are triggered, and all keys of the English input method are triggered before the content changes enter the event callback.
keypress:
Chrome:
1. Chinese input method function key triggers, English input method all keys trigger;
Safari:
1. All keys of Chinese input method are not triggered, while all keys of English input method are triggered.
