Input

Input data using mouse or keyboard.

:::warning

Input is a controlled component, it always shows Vue binding value.

Under normal circumstances, input event should be handled. Its handler should update component's binding value (or use v-model). Otherwise, input box's value will not change.

Do not support v-model modifiers.
