The DOM CompositionEvent
represents events that occur due to the user indirectly entering text.
For compositionstart
events, this is the currently selected text that will be replaced by the string being composed. This value doesn't change even if content changes the selection range; rather, it indicates the string that was selected when composition started.
For compositionupdate
, this is the string as it stands currently as editing is ongoing.
For compositionend
events, this is the string as committed to the editor.
