请问如何暴露函数给父组件这个写法，有解吗？

@Charlie500

ctx.expose({
  myClick,
});

[Charlie500]

you can paste my code to your ide , expose is not defined in ctx @funny-family

[funny-family]

@Charlie500, that is why.

export interface FunctionalComponent<P = {}, E extends EmitsOptions = {}>
  extends ComponentInternalOptions {
  // use of any here is intentional so it can be a valid JSX Element constructor
  (props: P, ctx: Omit<SetupContext<E>, 'expose'>): any
  props?: ComponentPropsOptions<P>
  emits?: E | (keyof E)[]
  inheritAttrs?: boolean
  displayName?: string
  compatConfig?: CompatConfig
}

Try to console log ctx, if expose exists inside this object it must be mistake in type definition of Functional Component.

@Charlie500, or you can try use defineExpose

纯函数不行。我刚看了一下代码，你定义到defineComponent里面的setup应该可以
