下面的代码给出
List.js
import React from 'react';
import { connect, bindActionCreators } from 'react-redux';
import PostList from '../components/PostList'; // Component I wish to wrap with actions and state
import postList from '../Actions/PostList' //Action Creator defined by me
const mapStateToProps = (state, ownProps) => {
return state.postsList
}
const mapDispatchToProps = (dispatch) => {
return bindActionCreators({"postsList":postList},dispatch)
}
export default connect(mapStateToProps, mapDispatchToProps)(PostList);
PostList.js
import React from 'react'
export const PostList = (props) => {
return <div>List</div>
}
请帮我解决方案?
最佳答案
您正在执行import PostList from '../components/PostList';
,因此需要在PostList.js文件中使用export default
。
否则,您需要执行import { PostList } from '../components/PostList';
。

关于javascript - 您必须将组件传递给connect返回的函数。而是收到未定义,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/42324317/
