Question

我有一个导航栏，里面有一个表格。我希望将onSubmit上的所有数据发送到Firebase实时数据库。但是，当我绑定onSubmit函数时，它什么也没有起作用。我的按钮或表单（不确定）在onSubmit上未检测到任何操作

我尝试将onSubmit字段直接放在Button中，结果相同，没有任何作用。我尝试在handleSubmit函数中添加console.log，以查看当我单击Button时它是否正常工作，什么也没发生。我的控制台空着。我也将表格从导航栏中放出来只是为了进行测试。结果相同，无法正常工作。

有人有什么想法要发生吗？ app.js

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      sheetLoaded: false,
      isNotClicked: true,
      isMoreFiltersNotRequired: true,
      handleShopClick: false,
      selectedOption: "option1",
      cabinePhoto: false,
      bornePhoto: false,
      helioBooth: false,
      filteredResults: [],
      filteredResultsLength: 0,
      rating: 5,
      shops: [],
      loading: true,
      zip_code: "",
      searchResult:""
    };
    //To resolve clone App error when we are initializing App

    if (!firebase.apps.length) {
      firebase.initializeApp(config);
    }
  }

  checkLoading = () => {
    if (this.state.loading === true) {
      console.log("loading...");
    } else if (this.state.loading === false) {
      console.log("Finish load");
    }
  };

  getUserData = () => {
    let ref = firebase.database().ref("shops");
    ref.on("value", snapshot => {
      const state = snapshot.val();
      this.setState({
        shops: state,
        loading: false
      });
    });
  };

  componentWillMount() {
    this.checkLoading();
    this.getUserData();
  }

  handleChanges = e => {
    const input = e.currentTarget;
    const name = input.name;
    const value = input.type === "checkbox" ? input.checked : input.value;
    this.setState({ [name]: value });
  };

  handleSubmit = (e) =>{
    console.log('search clicked')
    e.preventDefault();
    const itemsRef = firebase.database().ref('search');
    const result = {
      zip_code: this.state.zip_code,
      selectedOption: this.state.selectedOption
    }
    itemsRef.push(result);
    this.setState({
      zip_code: '',
      selectedOption: ''
    });
  }

    );
  }

export default HeaderFilters;

Answer 1

尝试删除<Link to = "/search" >，我认为这可以防止在父级中发生点击

Answer 2

尝试绑定您的提交功能

 constructor(props) {
    super(props);
    this.state = {
      sheetLoaded: false,
      isNotClicked: true,
      isMoreFiltersNotRequired: true,
      handleShopClick: false,
      selectedOption: "option1",
      cabinePhoto: false,
      bornePhoto: false,
      helioBooth: false,
      filteredResults: [],
      filteredResultsLength: 0,
      rating: 5,
      shops: [],
      loading: true,
      zip_code: "",
      searchResult:""
    };
    //To resolve clone App error when we are initializing App

    if (!firebase.apps.length) {
      firebase.initializeApp(config);
    }

    this.handleSubmit = this.handleSubmit.bind(this)
  }

onSubmit无法与react-bootstrap表单一起使用
