如何将多个actionCreator包装成一个道具？

Question

我收到以下错误：

Uncaught TypeError: this.props.dispatch is not a function

这是我的组件：

import React from 'react';
import PropTypes from 'prop-types';
import {Link} from 'react-router-dom';
import {connect} from 'react-redux';
import {bindActionCreators} from 'redux';
import * as jobTitleSkillsActions from '../../actions/jobTitleSkillsActions';
import SkillList from './SkillList';
import * as userPositionActions from '../../actions/userPositionActions';

class SkillPage extends React.Component {

  componentDidMount() {
    this.props.dispatch(userPositionActions.loadUserPositions());
    var job_title_id = this.props.user_positions[0].job_title_id;    this.props.dispatch(jobTitleSkillsActions.loadJobTitleSkills(job_title_id));
  }

.....

const mapStateToProps = state => {
  return {
    job_title_skills: state.job_title_skills,
    user_positions: state.user_positions
  };
};

function mapDispatchToProps(dispatch) {
  return {
    actions: {
      userPositionActions: bindActionCreators(userPositionActions, dispatch),
      jobTitleSkillsActions: bindActionCreators(jobTitleSkillsActions, dispatch),
    }
  };
}

export default connect(mapStateToProps, mapDispatchToProps)(SkillPage);

我在这里做错了什么？

Answer 1

由于您已经使用过mapDispatchToProps，dispatch因此该组件将无法作为道具使用。由于您已经使用过mapDisptachToProps，作业操作将作为道具提供，您可以像这样使用它们

componentDidMount() {
    this.props.actions.userPositionActions.loadUserPositions());
    var job_title_id = this.props.user_positions[0].job_title_id;
    this.props.actions.jobTitleSkillsActions.loadJobTitleSkills(job_title_id));
  }

但是您可以进一步简化它，例如

function mapDispatchToProps(dispatch) {
  return bindActionCreators({userPositionActions, jobTitleSkillsActions}, dispatch)  
}

...


componentDidMount() {
    this.props.userPositionActions.loadUserPositions());
    var job_title_id = this.props.user_positions[0].job_title_id;
    this.props.jobTitleSkillsActions.loadJobTitleSkills(job_title_id));
  }
