如何使用react-redux构建多步骤表单流,每步更改一次URL

我正在努力构建一个多步骤表单流,用户首先加载:/welcome,然后让用户通过以下内容

step 0: `/welcome` (Should redirect to step 1)
step 1: `/welcome/workplace`
step 2: `/welcome/profile`

这是我到目前为止所做的:

App.jsx:

import Welcome from '../containers/welcome/Welcome';

const App = ({store}) => {
  return (
    <StoreProvider store={store}>
      <ConnectedRouter history={history}>
        <Switch>
          <PrivateRoute exact path="/welcome" layout={MainLayout} component={Welcome} />
          <WithMainLayout exact path="/" component={Home} />
          <AuthRoutes path={`/${clientResourceName}`} wrapper={WithMainLayout} />
          <WithMainLayout component={NotFound} />
        </Switch>
      </ConnectedRouter>
    </StoreProvider>
  );
};

Welcome.js

import React from 'react';
import WorkPlacePage from '../../components/welcome/WorkPlacePage';

class Welcome extends React.Component {

  constructor(props) {
    super(props);
    this.state = {
      step: 1
    };
  }

  showStep() {
    const {history} = this.props

    console.log('showStep');
    console.log({history})

    switch (this.state.step) {
      case 1:
        return <WorkPlacePage history={history} />
      default:
        return (
          <div>
            <h1>Case: Default</h1>
          </div>
        );
    }
  }

  render() {
    var style = {
      width : (this.state.step / 4 * 100) + '%'
    }
    return (
      <main>
        <span className="progress-step">Step {this.state.step}</span>
        <progress className="progress" style={style}></progress>
        {this.showStep()}
      </main>
    )
  }
}

export default Welcome;

WorkPlacePage.js

import React from 'react';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';

class WorkPlacePage extends React.Component {

  render() {

    console.log('this.props.history')
    console.log(this.props.history)

    return (
      <div>
        <h1>Workplace</h1>
        <span>
        survey things
        <button onClick={() => this.props.history.push("/confirmation")}>next page</button>
        </span>
      </div>
    );
  }
}

export default WorkPlacePage;

作为反应,我可以使用你的建议:

  1. 我是否正确构建了这个多步骤表单?
  2. 如果用户在浏览器中加载/welcome,则将浏览器自动重定向到第1步的正确方法是/welcome/workplace
  3. 在WorkplacePage.js上,单击“下一步”按钮时出现以下JS错误:=Uncaught TypeError: Cannot read property 'push' of undefined ---为什么没有定义历史记录?
  4. 感谢您提供任何专家帮助!

答案 0 :(得分:1)

  1. 是的,确定这个结构看起来不错。我认为您希望为每个步骤创建一个单独的路径组件,因为我确信每个步骤都会随着更多规则和验证而增长。

  2. 要重定向,您可以呈现<Redirect to="/somewhere/else"/> - https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/api/Redirect.md

  3. 您需要将道具传递到<WorkPlacePage />

  4. 类似的东西:

    class Welcome extends React.Component {
    
      constructor(props) {
        super(props);
        this.state = {
          step: 1
        };
      }
    
      render() {
        const {history} = this.props
        switch (this.state.step) {
          case 1:
            return <WorkPlacePage history={history} />
          case 2:
            return (
              <div>
                <h1>WIP</h1>
              </div>
            );
          default:
            return (
              <div>
                <h1>Case: Default</h1>
              </div>
            );
            }
    
      }
    }
