提问by Riya Kapuria

How to reload current page in ReactJS? in case of javascript we can wrote window.location.reload();How to do the same in reactjs? I'm able to add new data by UI. But without refresh I'm not able to see the list. I want whenever I'm adding some data that time itself.

如何在 ReactJS 中重新加载当前页面？在 javascript 的情况下，我们可以写window.location.reload();如何在 reactjs 中做同样的事情？我可以通过 UI 添加新数据。但是如果不刷新，我将无法看到列表。每当我添加一些数据时，我都想要。

onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {

      if(response.data.status == 200){
      let result =  self.state.buckets.concat(response.data.buckets)
      }else{
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }

Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount()in a React class.

由于 React 最终归结为普通的旧 JavaScript，因此您真的可以将它放在任何地方！例如，您可以将它放在componentDidMount()React 类中的 a 上。

For you edit, you may want to try something like this:

对于您编辑，您可能想尝试这样的事情：

class Component extends React.Component {
  constructor(props) {
    super(props);
    this.onAddBucket = this.onAddBucket.bind(this);
  }
  componentWillMount() {
    this.setState({
      buckets: {},
    })
  }
  componentDidMount() {
    this.onAddBucket();
  }
  onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {
      if (response.data.status == 200) {
        this.setState({
          buckets: this.state.buckets.concat(response.data.buckets),
        });
      } else {
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }
  render() {
    return (
      {this.state.bucket}
    );
  }
}

window.location.reload();

回答by Tiago Alves

You can use window.location.reload();in your componentDidMount()lifecycle method. If you are using react-router, it has a refresh methodto do that.

您可以window.location.reload();在componentDidMount()生命周期方法中使用。如果您正在使用react-router，它有一个刷新方法来做到这一点。

Edit: If you want to do that after a data update, you might be looking to a re-rendernot a reloadand you can do that by using this.setState(). Here is a basic example of it to fire a re-renderafter data is fetched.

编辑：如果您想在数据更新后执行此操作，您可能正在寻找一个re-rendernot areload并且您可以使用this.setState()来做到这一点。这是re-render在获取数据后触发 a 的基本示例。

import React from 'react'

const ROOT_URL = 'https://jsonplaceholder.typicode.com';
const url = `${ROOT_URL}/users`;

class MyComponent extends React.Component {
    state = {
        users: null
    }
    componentDidMount() {
        fetch(url)
            .then(response => response.json())
            .then(users => this.setState({users: users}));
    }
    render() {
        const {users} = this.state;
        if (users) {
            return (
                <ul>
                    {users.map(user => <li>{user.name}</li>)}
                </ul>
            )
        } else {
            return (<h1>Loading ...</h1>)
        }
    }
}

export default MyComponent;
