Reactjs 为什么可以';我不能在我的redux reducer中称之为.state吗?
我制作了一个获取管理员的reducer,当我在reducer中调用它时,我想让它显示某些管理员,但我没有定义 我对redux还很陌生,所以为我的错误道歉。 我试图包括所有相关文件夹: App.jsReactjs 为什么可以';我不能在我的redux reducer中称之为.state吗?,reactjs,redux,Reactjs,Redux,我制作了一个获取管理员的reducer,当我在reducer中调用它时,我想让它显示某些管理员,但我没有定义 我对redux还很陌生,所以为我的错误道歉。 我试图包括所有相关文件夹: App.js import React, { Component } from 'react'; import { connect } from 'react-redux'; import * as actions from '../store/actions'; class App extends Compon

当我console.log(action.admins)
在开关盒内获取columnsReducer.js文件中的\u admins时,我可以看到我想要的所有管理信息,有没有办法使columnsReducer.js文件中的状态全局化,以便我可以读取它
感谢您的帮助 在connect方法中使用MapStateTops。如下
let mapStateToProps = (state)=>{
return {
admins :[yourcolumnsReducer].admins
}
}
let app = connect(mapStateToProps, actions)(App);
//您可以在组件中使用this.props.admins
@satishkumar您没有将
mapstatetops
作为connect
的第一个参数传递。
