vuex 2.3.0 的发布说明: Modules can now declare state using a function - this allows the same module definition to be reused (e.g. multiple times in the same store, or in multiple stores)
假如你 vuex 的模块有多个格式是完全一样的, 这时候就可以把这个模块公共出来, 在 Vuex 实例里引用, 如:
import api from '~api'
const actions = {
async ['get']({commit, rootState: {route: { path }}}, config = {}) {
const { data: { code, data } } = await api.post(config.url, config.data)
if (code === 1001) commit('receive', data)
}
}
const mutations = {
['receive'](state, data) {
state.data = [].concat(data)
},
['modify'](state, payload) {
const index = state.data.findIndex(item => item.id === payload.id)
if (index > -1) {
state.data.splice(index, 1, payload)
}
},
['insert'](state, payload) {
state.data = [payload].concat(state.data)
},
['remove'](state, id) {
const index = state.data.findIndex(item => item.id === id)
state.data.splice(index, 1)
}
}
const getters = {
['get'](state) {
return state.data
}
}
export const _actions = actions
export const _mutations = mutations
export const _getters = getters
export default {
namespaced: true,
actions,
mutations,
getters
}
import Vue from 'vue'
import Vuex from 'vuex'
import lists from './general/lists'
Vue.use(Vuex)
export default new Vuex.Store({
namespaced: true,
modules: {
base: {
namespaced: true,
modules: {
app: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }},
platform: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }},
product: {
namespaced: true,
modules: {
category: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }},
}
},
keyword: {
namespaced: true,
modules: {
username: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }},
}
},
}
},
buzz: {
namespaced: true,
modules: {
shop: {...lists, state: { lists: { data: [], total: 0, current_page: 1 } }},
}
}
})
但是 state 却需要每个单独设置, 如果直接设置在lists里, 会导致 state 对象被引用共享
在 vuex@2.3.0 中, 这个问题将不存在
import api from '~api'
const actions = {
async ['get']({commit, rootState: {route: { path }}}, config = {}) {
const { data: { code, data } } = await api.post(config.url, config.data)
if (code === 1001) commit('receive', data)
}
}
const mutations = {
['receive'](state, data) {
state.data = [].concat(data)
},
['modify'](state, payload) {
const index = state.data.findIndex(item => item.id === payload.id)
if (index > -1) {
state.data.splice(index, 1, payload)
}
},
['insert'](state, payload) {
state.data = [payload].concat(state.data)
},
['remove'](state, id) {
const index = state.data.findIndex(item => item.id === id)
state.data.splice(index, 1)
}
}
const getters = {
['get'](state) {
return state.data
}
}
export const _actions = actions
export const _mutations = mutations
export const _getters = getters
export default {
namespaced: true,
state() {
return { lists: { data: [], total: 0, current_page: 1 } }
},
actions,
mutations,
getters
}
import Vue from 'vue'
import Vuex from 'vuex'
import lists from './general/lists'
Vue.use(Vuex)
export default new Vuex.Store({
namespaced: true,
modules: {
base: {
namespaced: true,
modules: {
app: lists,
platform: lists,
product: {
namespaced: true,
modules: {
category: lists,
}
},
keyword: {
namespaced: true,
modules: {
username: lists,
}
},
}
},
buzz: {
namespaced: true,
modules: {
shop: lists,
}
}
})

暂无浅谈Vuex@2.3.0 中的 state 支持函数申明的评论...
稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
