Vue官方文档（50）: vuex中Action的用法

1.在store中定义Action
store.js

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

const store = new Vuex.Store({
  state: {
    count: 0,
  },
  mutations: {
    increment (state) {
      state.count++
    },
  },
  actions: {
    increaseIt (context) {
      context.commit('increment')
    }
  }
})
export default store;

2.在页面中通过dispatch触发Action

import store from './store/store'

store.dispatch("increaseIt");
