react dva 怎么更改state?
react dva框架 点击修改state的值 类似react中的this.state和this.setState()
先展示下
点击改变前state的值
点击改变后state的值的变化
首先创建者两个文件
routes目录下的DvaState.js
import React from 'react';import { connect } from 'dva';import { Link } from 'dva/router';let count = 0const DvaState = ({
dispatch, dvaState, }) => { const {dataList} = dvaState
console.log(dataList)
console.log(dvaState) const handleChangeState = () => {
dispatch({ type:'dvaState/changeState', payload:{ dataList:[
{ list1: count++, list2: 'list22', list3: 'list33' }, { list2:'111' }
]
}
})
} return (
dvaState
{dataList[0].list1}
);};export default connect(({ dvaState }) => ({
dvaState
}))(DvaState);models 目录下的 dvaState.js
export default { namespace: 'dvaState', state: { dataList:[
{ list1:'a', list2:'c', }
]
}, subscriptions: { setup({ dispatch, history }) {
}, }, effects: {
}, reducers: { changeState(state, {payload}) { return {...state, ...payload}
}
},};推荐学习：《react视频教程》
