这段代码指的是哪个 setInputValue?

Which setInputValue is this code referring to?

我在学习 React 的第 2 天,我不明白下面的代码指的是哪个 setInputValue

const [inputValue, setInputValue] = useState("explore");行,setInputValue是一个设置状态的函数。但是在第 <SearchCollections setInputValue={setInputValue} /> 行还有两个 setInputValue。那么哪个是哪个?为什么会有 setInputValue 属性?

  const [inputValue, setInputValue] = useState("explore");

  useEffect(() => {
    if (isAuthenticated && !isWeb3Enabled && !isWeb3EnableLoading) enableWeb3();
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [isAuthenticated, isWeb3Enabled]);

  return (
    <Layout style={{ height: "100vh", overflow: "auto" }}>
      <Router>
        <Header style={styles.header}>
          <SearchCollections setInputValue={setInputValue} />
          <Menu
            theme="light"
            mode="horizontal"
            style={{
              display: "flex",
              fontSize: "17px",
              fontWeight: "500",
              marginLeft: "50px",
              width: "100%",
            }}
            defaultSelectedKeys={["nftMarket"]}

更新:这是 SearchCollections 组件。

import { Select } from 'antd';
import { useMoralisDapp } from "providers/MoralisDappProvider/MoralisDappProvider";
import { getCollectionsByChain } from "helpers/collections";


function SearchCollections({setInputValue}){
    const { Option } = Select;
    const { chainId } = useMoralisDapp();
    const NFTCollections = getCollectionsByChain(chainId);
    
    

    function onChange(value) {
        setInputValue(value);
    }

    return (
        <>
        <Select
            showSearch
            style={{width: "1000px",
                    marginLeft: "20px" }}
            placeholder="Find a Collection"
            optionFilterProp="children"
            onChange={onChange}
        >   
        {NFTCollections && 
            NFTCollections.map((collection, i) => 
            <Option value={collection.addrs} key= {i}>{collection.name}</Option>
            )
            }   
        </Select>
            
        </>
    )
}

打开 SearchCollections 组件。很可能您没有使用状态管理工具,而是将挂钩传递给该组件以使用它。
