Question

我是全栈开发的新手，我正在尝试向我的客户端（带有 MUI 和 Redux 的 React Js）添加一个搜索栏，用于在云 Firestore 集合中搜索文档名称（或文档中的值） .我不知道该怎么做，有什么建议吗？我会向您展示我的导航栏代码（我将在其中添加搜索栏）。

const styles = {

 class Navbar extends Component {
    constructor(props) {
        super(props);
        this.state = {
          open: false,
          game:'ygo',
          query:'',

    gameChange = (event) => {
        this.setState({game: event.target.value});
    };

    searchChange = (event) =>{
        this.setState({query: event.target.value})
    }

    render() {
        var { authenticated, classes} = this.props;
        //const [open, setOpen] = useState(false);
        const handleDrawer = () =>{
            this.setState({ open: true })
        }
        const { open } = this.state;
        const ITEM_HEIGHT = 48;
        const ITEM_PADDING_TOP = 8;
        const MenuProps = {
            PaperProps: {
              style: {
                maxHeight: ITEM_HEIGHT * 4.5 + ITEM_PADDING_TOP,
                width: 250,
              },
            },
        };
        if(authenticated===true){
            var { authenticated, classes,user:{credentials:{ygo,mtg,kf}}} = this.props;
        }


        return (
            
            <AppBar position="fixed">
                <Toolbar className="nav-container">
                    {authenticated ? (
                        <Fragment>

                            <TextField

                                value={this.state.query}
                                onChange={this.searchChange}
                                floatingLabelFixed
                            />

                        </Fragment>
                        

                    ):(
                        <Fragment>
                            <Button color="inherit" component={Link} to="/login">Login</Button>
                            <Button color="inherit" component={Link} to="/signup">Singup</Button>
                            <Button color="inherit" component={Link} to="/">Home</Button>
                        </Fragment>
                    )}
                </Toolbar>
            </AppBar>

            
        )
    }
}

Navbar.propTypes = {
    authenticated:  PropTypes.bool.isRequired,
    user: PropTypes.object.isRequired,
    classes: PropTypes.object.isRequired
}

const mapStateToProps = state =>({
    authenticated: state.user.authenticated,
    user: state.user,
    game: state.UI
})

export default connect(mapStateToProps)(withStyles(styles)(Navbar))
