一、各个模块的作用：
代码语言：javascript复制state 用来数据共享数据存储
mutation 用来注册改变数据状态（同步）
getters 用来对共享数据进行过滤并计数操作
action 解决异步改变共享数据（异步）二、 创建文件：
代码语言：javascript复制actions.js
getters.js
index.js
mutations.js
mutation-types.js
state.js三、编辑文件
这里只是拿出自己的项目来做一个例子，只是介绍封装的方法。
index.js
import Vue from ‘vue’ import Vuex from ‘vuex’ import * as actions from ‘./actions’ import * as getters from ‘./getters’ import state from ‘./state’ import mutations from ‘./mutations’ import createLogger from ‘vuex/dist/logger’ // vuex调试工具
Vue.use(Vuex)
const debug = process.env.NODE_ENV !== ‘prodycution’ // 开发环境下开启严格模式
export default new Vuex.Store({ actions, getters, state, mutations, strict: debug, plugins: debug ? [createLogger()] : [] })
state.js
import {playMode} from ‘common/js/config’ import {loadSearch} from ‘common/js/cache’
const state = { singer: {}, playing: false, fullScreen: false, playlist: [], sequenceList: [], mode: playMode.sequence, currentIndex: -1, disc: {}, topList: {}, searchHistory: loadSearch() }
export default state
mutations.js
import * as types from ‘./mutation-types’
const mutations = { [types.SET_SINGER](state, singer) { state.singer = singer }, [types.SET_PLAYING_STATE](state, flag) { state.playing = flag }, [types.SET_FULL_SCREEN](state, flag) { state.fullScreen = flag }, [types.SET_PLAYLIST](state, list) { state.playlist = list }, [types.SET_SEQUENCE_LIST](state, list) { state.sequenceList = list }, [types.SET_PLAY_MODE](state, mode) { state.mode = mode }, [types.SET_CURRENT_INDEX](state, index) { state.currentIndex = index }, [types.SET_DISC](state, disc) { state.disc = disc }, [types.SET_TOP_LIST](state, topList) { state.topList = topList }, [types.SET_SEARCH_HISTORY](state, history) { state.searchHistory = history } }
export default mutations
mutation-types.js
export const SET_SINGER = ‘SET_SINGER’
export const SET_PLAYING_STATE = ‘SET_PLAYING_STATE’
export const SET_FULL_SCREEN = ‘SET_FULL_SCREEN’
export const SET_PLAYLIST = ‘SET_PLAYLIST’
export const SET_SEQUENCE_LIST = ‘SET_SEQUENCE_LIST’
export const SET_PLAY_MODE = ‘SET_PLAY_MODE’
export const SET_CURRENT_INDEX = ‘SET_CURRENT_INDEX’
export const SET_DISC = ‘SET_DISC’
export const SET_TOP_LIST = ‘SET_TOP_LIST’
export const SET_SEARCH_HISTORY = ‘SET_SEARCH_HISTORY’
