Tags: composition

beforeinput and input events have different inputType values

During IME composition or in certain browser/IME combinations, the beforeinput event may have a different inputType than the corresponding input event. For example, beforeinput may fire with insertCompositionText while input fires with deleteContentBackward. This mismatch can cause handlers to misinterpret the actual DOM change and requires storing beforeinput's targetRanges for use in input event handling.

Selection mismatch between beforeinput and input events

The selection (window.getSelection()) in beforeinput events can differ from the selection in corresponding input events. This mismatch can occur during IME composition, text prediction, or when typing adjacent to formatted elements like links. The selection in beforeinput may include adjacent formatted text, while input selection reflects the final cursor position.

getTargetRanges() returns empty array in beforeinput events

The getTargetRanges() method in beforeinput events may return an empty array or undefined in various scenarios, including text prediction, certain IME compositions, or specific browser/device combinations. When getTargetRanges() is unavailable, developers must rely on window.getSelection() as a fallback, but this may be less accurate.
