我试图将一个变量传递给Redux操作,但该操作正在接收未定义的,我做错了什么

index.js-我在哪里调用操作

import React from 'react'
import { connect } from 'react-redux'
import * as documentActions from '../../services/redux/actions/document'

function Document(props) {
    return (
        <ul className="list-group group">
            <li className="list-group-item group-item" 
                name = 'group'
                onClick={() => props.toggleDoc(1)}>
                {props.data.name}
            </li> 
        </ul>
    )
}
const mapStateToProps = state => {
    return {
        selectedId: state.selectedId
    }
}
const mapDispatchToProps = dispatch => {
    return {
        toggleDoc: () => dispatch(documentActions.toggleDoc())
    }
}
export default connect(
    mapStateToProps,
    mapDispatchToProps
)(Document)
减速器

import * as types from '../types'

const initialState = {
  selectedId: null
}

export default function toggleDoc(state = initialState, action) {
  console.log('action')
  console.log(action.payload)
  switch (action.type) {
    case types.TOGGLE_DOC:
      return {
        ...initialState,
        selectedId: action.payload
      }
    default:
      return state
  }
}

道具。toggleDoc
mapDispatchToProps
中定义。您已将其定义为:

toggleDoc:()=>dispatch(documentActions.toggleDoc())
此定义不接受任何参数,即使
documentActions.toggleDoc
可以。您需要更改定义以传递该参数:

toggleDoc:(id)=>dispatch(documentActions.toggleDoc(id))
