如何从 javascript 文件(而不是 vue 组件)调度动作?

How to dispatch action from a javascript file (instead of a vue component)?

我在 vue 上下文之外有一个模块(javascript 文件)。我需要从这个 javascript 文件中发送动作。可能吗 ?如果是,那怎么办?

jsfile.js(Javascript 文件)

const detail = {};

detail.validateLocation = (location) => {
  // need to dispatch one action from here.
  // dispatch('SET_LOCATION', {city: 'California'})
  // how to dispatch action ?
}

export default detail;

action.js

export default {
  SET_LOCATION: ({ commit}, data) => {
    commit('SET_LOCATION', data);
  },
}

store.js

import Vue from 'vue';
import Vuex from 'vuex';
import actions from './actions';
import mutations from './mutations';
import getters from './getters';
export function createStore() {
  return new Vuex.Store({
    modules: {},
    state: {
      location: null
    },
    actions,
    mutations,
    getters,
  });
}

首先,在store.js.

中创建商店
import Vue from 'vue';
import Vuex from 'vuex';
import actions from './actions';
import mutations from './mutations';
import getters from './getters';

const store = new Vuex.Store({
    modules: {},
    state: {
      location: null
    },
    actions,
    mutations,
    getters,
  });

export default store

然后,将商店导入jsfile.js并使用它。

import store from "./store"

const detail = {};

detail.validateLocation = (location) => {
  // Use imported store
  store.dispatch('SET_LOCATION', {city: 'California'})
}

export default detail;

假设您有一个创建 Vue 实例的主文件或索引文件,您现在可能需要将导入从导入创建函数更改为仅导入商店。
