一、在store文件中新建csjVar.js文件

const csjVar = {csjMess: [{aaa:"ok"},{bbb:"no"}]
}
export default csjVar

二、修改store文件中新建index.js文件

import Vue from 'vue'
import Vuex from 'vuex'
import user from '@/store/modules/user'
import getters from './getters'
import csjVar from './csjVar.js'Vue.use(Vuex)const store = new Vuex.Store({modules: {user},state: {// 添加 csjVar 到 Vuex 的 statecsjVar},mutations: {// 创建一个 mutation 来改变 csjMess 的值SET_CSJMESS(state, value) {state.csjVar.csjMess = value}},getters,
})export default store

三、index.vue中读取和修改

<script>import store from '@/store'export default {data() {return {webUrl: '',}},methods: {onLoad: function(query) {console.log("全局变量：csj");var sss = this.$store.state.csjVar.csjMess;console.log(this.$store.state.csjVar.csjMess);console.log(this.$store.state.csjVar.csjMess[0].aaa);console.log(this.$store.state.csjVar.csjMess[1].bbb);// 遍历sss,修改每个元素的aaa和bbb属性值  	sss.forEach(item => {if (item.aaa) {item.aaa = 'Changed ' + item.aaa   // 修改aaa的值}if (item.bbb) {item.bbb = 'Changed ' + item.bbb  // 修改bbb的值}})// 提交mutation来修改csjMess	this.$store.commit('SET_CSJMESS', sss)console.log(this.$store.state.csjVar.csjMess[0].aaa);console.log(this.$store.state.csjVar.csjMess[1].bbb);},}}
</script>
