示例1: maybeNullWebkitIE
/**
* Common logic between Webkit and IE for deciding whether we want the keydown
* or the keypress
*/
private static boolean maybeNullWebkitIE(boolean ret, int typeInt,
KeySignalType type) {
// Use keydown as the signal for everything except input.
// This is because the mutation always happens after the keypress for
// input (this is especially important for chrome,
// which interleaves deferred commands between keydown and keypress).
//
// For everything else, keypress is redundant with keydown, and also, the resulting default
// dom mutation (if any) often happens after the keydown but before the keypress in webkit.
// Also, if the 'Command' key is held for chrome/safari etc, we want to get the keydown
// event, NOT the keypress event, for everything because of things like ctrl+c etc.
// where sometimes it'll happen just after the keydown, or sometimes we just won't
// get a keypress at all
