Javascript 减速器更新了ApporarRayProp,但Redux没有';不要更新我的视图
我是Redux的新手,我想在调用API后更新数组this.props.apposArrayProp,但是我被卡住了,操作和减速器都被执行了,但是视图无论如何都不会改变。我不知道连接方法中是否需要mapDispatchToProps My actions.js文件Javascript 减速器更新了ApporarRayProp,但Redux没有';不要更新我的视图,javascript,reactjs,redux,Javascript,Reactjs,Redux,我是Redux的新手,我想在调用API后更新数组this.props.apposArrayProp,但是我被卡住了,操作和减速器都被执行了,但是视图无论如何都不会改变。我不知道连接方法中是否需要mapDispatchToProps My actions.js文件 import fetch from 'isomorphic-fetch' export const RECEIVE_APPOS = 'RECEIVE_APPOS' export function fetchAppos(appo_

致:

听从你的建议,现在一切都成了一种魅力。谢谢 您的
MapStateTops
函数应该如下所示:
const mapStateToProps = (state) => {
return {
apposArrayProp: state.appointments_Rdcer.apposArrayProp
};
};
这应该足以让它工作
此外,我还鼓励您查看渲染逻辑。您使用的是
Array#map
,就像使用Array#forEach
一样。您所拥有的功能仍然可以使用,但有点难看。您的MapStateTrops
函数应该如下所示:
const mapStateToProps = (state) => {
