Documentation for this class was provided by MDN. var data(default,null) : String
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.
