从不可变导入 get 方法但无法在我的选择器中读取

Question

我在我的 React 项目中使用了 Immutable JS，我想在我的选择器文件中使用 get 方法，但它无法被我的 "getAllAppointments" 和 "getQuery" 函数识别。

import {createSelector} from 'reselect'
import {get} from 'immutable'

const getAllAppointments = state => state.get('allAppointments')

const getQuery = state => state.get('query')

export const getVisibleAppointments = createSelector(
    getAllAppointments,
    getQuery,
    (appointment, query) => {
        return (!query) ?
            appointment :
            appointment.filter(item => item.title.toLowerCase().includes(query))
    }
)

Answer 1

来自 Immutable.js 文档 https://immutable-js.github.io/immutable-js/docs/#/get get 运算符不能那样工作。

尝试使用它：

const getAllAppointments = state => get(state, 'allAppointments')

const getQuery = state => get(state, 'query')
