React从api获取更多输入字段

问题描述

我是新来的人。我有一个输入字段，用户可以在其中搜索位置，哪些API可以帮助获得有效的结果。

用户可以添加多个位置

我可以添加多个输入字段并从API获取信息，但问题是无法在下拉列表或其他提示中将其显示为建议。如何在该输入字段的确切索引中设置结果？每当输入字段被单击时，display状态集ture。仅在单击输入字段时才需要使其true

这是我到目前为止所做的

function MultiWay2(props) {
    const [inputLimit,setinputLimit] = useState(0);

    const [display,setdisplay] = useState(false)
    const [location,setlocation] = useState([])
    const [locationCode,setlocationCode] = useState('')
    const onSubmit = () => {
        console.log(locationCode)
        //some action
    }
    const SearchLocation = (location,index) => {        
        Axios.get('https://api.com/location/search',{
            headers: {
                "api-key": 12345,},params: {
                "query": location
            }
        })
            .then(response => {
                // console.log(response.data)
                setlocation(response.data)
                setdisplay(true)

            })
            .catch((error) => {
                console.log(error)
            })
    }
    const [inputList,setinputList] = useState([
        { location: '',])

    const addanother = (e,index) => {
        const list = [...inputList];
        setinputLimit(inputLimit + 1)
        setinputList([...inputList,{ location: "" }])
    }
    const handleChange = (e,index) => {
        const { name,value } = e.target;
        const list = [...inputList];
        list[index][name] = value
        setinputList(list)
    }
    const removeanother = index => {
        const list = [...inputList];
        list.splice(index,1)
        setinputLimit(inputLimit - 1)
        setinputList(list)
    }
    return (
