因为形成了闭包,导致获取不到新的 props,可以通过 useRef 的方式处理一下

const ref = useRef(props)
useEffect(() => {
    ref.current = props
}, [props])

const loadMore = (done: () => void) => {
    setTimeout(() => {
        console.log('loadmore',ref.current)
        const curLen = defultList.length
        for (let i = curLen; i < curLen + 10; i++) {
            defultList.push(`${i}`)
        }
        if (defultList.length >= 30) {
            setHasMore(false)
        } else {
            setDefultList([...defultList])
        }
        done()
    }, 500)
}
