vuex方法封装调用

vuex

https://vuex.vuejs.org/zh/guide/mutations.html

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'

// 插件，mutations修改state时会记录并显示修改日志
import createLogger from 'vuex/dist/logger'

Vue.use(Vuex)

// vuex中的调试工具，比较费性能，只在开发中使用
const debug = process.env.NODE_ENV !== 'production'

export default new Vuex.Store({
  actions,
  getters,
  state,
  mutations,
  strict: debug,
  plugins: debug ? [createLogger()] : []
})

state.js 定义vuex中状态变量

const state = {
  singer: {},
  
}

export default state

getters.js 过滤包装state变量

// 过滤并计算属性
export const singer = state => state.singer

actions.js 异步调用修改mutations中的方法

export const ran = function ({commit}, {list}) {
  commit(types.SET_SINGER, true)
}

mutations-type.js 封装mutations中的方法常量

// mutation 里用到的方法常量值
export const SET_SINGER = 'SET_SINGER'

mutations.js同步修改state中的变量

// 同步方法，修改state的值
import * as types from './mutation-types'

const mutations = {
  [types.SET_SINGER](state, singer) {
    state.singer = singer
  }
}

export default mutations
