问题描述
我收到以下错误:
未捕获的类型错误:this.props.dispatch 不是函数
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?
推荐答案
由于您已经使用了 mapDispatchToProps
,dispatch
将不能作为 prop 提供给组件.由于您使用了 mapDisptachToProps
,作业操作将作为道具提供,您可以像
Since you have already used mapDispatchToProps
, dispatch
wont be available to the component as a prop. Since you have used mapDisptachToProps
, the jobs actions will be available as props and you can use them like
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));
}
但是你可以进一步简化它
However you can simplify it further like
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));
}
