使用带参数的重选选择器 [英] Use reselect selector with parameters

问题描述

如何将其他参数传递给组合选择器？我正在尝试

How do I pass additional parameters to combined selectors? I am trying to

•获取数据

•过滤数据

•通过myValue为我的数据集/组数据添加自定义值

• Add custom value to my data set / group data by myValue

export const allData = state => state.dataTable
export const filterText = state => state.filter.get('text')

export const selectAllData = createSelector(
  allData,
  (data) => data
)

export const selectAllDataFiltered = createSelector(
  [ selectAllData, filterText ],
  (data, text) => {
    return data.filter(item => {
      return item.name === text
    })
  }
)

export const selectWithValue = createSelector(
  [ selectAllDataFiltered ],
  (data, myValue) => {
    console.log(myValue)
    return data
  }
)

let data = selectWithValue(state, 'myValue')

console.log（myValue）返回 undefined

简而言之，重新选择不支持传递给选择器的任意参数。建议的方法是，将相同的数据存储在Redux状态，而不是传递参数。

In short, reselect doesn't support arbitrary arguments passed to selectors. The recommended approach is, instead of passing an argument, store that same data in your Redux state.
