data 只读特性在 CompositionEvent interface returns the characters generated by the input method that raised the event; its exact nature varies depending on the type of event that generated the CompositionEvent 对象。

句法

 myData = CompositionEvent.data
					

值

A DOMString representing the event data:

• 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.
