dva的核心点

建立链接
@connect(({ task, loading }: any) => (
{
task: task.edit,
dictinfo: task.dictinfo,
loading
}
))

获取加载状态

loading={!!this.props.loading.effects['task/pageReward']}

发送请求

let { dispatch } = this.props;

dispatch({

type: 'task/setBenefitDLG',

payload: false,

});

 

使用 

import { produce } from 'immer';

 

changeCurrentMode(state, { payload }) {

return produce(state, (draftState: any) => {

state.edit.currentMode = payload;

state.dictinfo.taskTypeListChildList = state.dictinfo.taskTypeList.find(item => item.value === payload)?.taskPackageTypeList || []

});

},

 

如果属性在根节点上

//return {...state,GroupItems:payload}
