我有以下代碼：  const classes = useStyles();  const [data1, setData1] = useState([]);  const [searchedString, setSearchString] = useState("");  console.log(data1);  const fetchDataHandler = async () => {    setData1([]);    axios      .get(`http://localhost:5000/select?articul=${searchedString}`)      .then((response) => {        dataStruction(response.data);      })      .catch((err) => {        console.log(err);      });  };  const dataStruction = (data) => {    data.map((element1) => {      if (element1.secondaryArt.startsWith("30")) {        return setData1([...data1, { ...element1, level: 1 }]);      }    });  };  const onChangeSearchText = (event) => {    setSearchString(event.target.value);  };我希望每當(dāng)我調(diào)用 fetchDataHandler 時(shí)都能夠?qū)?data1 設(shè)置為空數(shù)組?，F(xiàn)在它正在工作，因?yàn)槊看挝艺{(diào)用 fetchDataHandler 時(shí)結(jié)果都會(huì)保留。我該怎么做？
