我遇到了一个与Redux (与React一起使用)的问题。这是我的代码:
/// <reference path="../../typings/index.d.ts"/>
import "./polyfill.ts";
import * as React from 'react'
import * as ReactDOM from 'react-dom'
import { createStore, combineReducers } from 'redux'
import { Provider, d
在我的React-Redux应用程序中,我正在更改redux state,它看起来像这样
state {
key1: oldVal1
key2: oldArray1 //The value here is an array
.
.
.
}
下一次我更新状态时...
state {
key1: newVal1
//But for key2 I want to keep the value as the same oldArray1
//Now since that oldArray1 is not anywhere except
使用React、Redux、Redux-thunk,我想通过服务器请求(API调用)获得一个初始状态,但我似乎无法让它工作。
到目前为止,我得到的是:
var Redux = require('redux');
var carReducer = require('./reducers/cars');
var thunk = require('redux-thunk').default;
var initialState = require('./reducers/initialState');
var rootReducer
第一次使用Redux时,我理解操作和还原器的概念,但无法让它们在我的代码中很好地发挥作用,我担心这是因为我使用的是CoffeeScript而不是ES6。
我想问题是,我不能在我的/app/reducers/index.export default ...中做¯\_,但老实说,Redux对我来说是非常新的,我和webpack一起蹒跚而行,反应了一段时间,而且仍然对两者都不太舒服,所以¯\_(ツ)_/ my
我不断地发现错误:
Store does not have a valid reducer. Make sure the argument passed to combineReducers
我是React/Redux的新手。任何帮助都会很好。我有一个组件,它对ComponentDidMount进行API调用以获取数据,然后更新我的Redux存储。该组件还使用connect获取Redux状态,并将其作为道具传递给哑组件。
componentDidMount() {
this.props.dispatch(fetchSite()) //this triggers the api call and updates the redux store.
}
return (
<div>
<Child
myprop={this.props.
我刚开始使用react/redux,并试图弄清楚store/state。我构建了一个组件,它成功地接收数据,然后将其传递给reducer。这是我的组件:
'use strict';
var React = require('react');
var PropTypes = React.PropTypes;
import axios from 'axios';
import store from '../../store';
import {getDataSuccess, getDataFail} from '../..
`
import React, {Component} from 'react';
import {connect} from 'react-redux';
import Chart from '../components/chart.js';
import GoogleMap from '../containers/googlemap';
import {removeCityMap} from '../actions/index';
import { bindActionCreators } from
