从孩子更改父 state

Question

我想从孩子改变父母 state

export const ParentComponent=()=>{

 const [ resendCodeStatus ,setResendCodeStatus ] = useState(false)

 const callback=()=>{

   setResendCodeStatus(!resendCodeStatus)

 }

 return (

   < Timer  callback={callback} />

 )
}

但我只能访问一次回调 function

尝试这个：

export const ParentComponent=()=>{

const [ resendCodeStatus ,setResendCodeStatus ] = useState(false)
const callbackFunction=()=>{
setResendCodeStatus((status) => !status)
}
return (
<Timer callbackFunction={callbackFunction} />
) }
