vue使用vuex的来同步状态

概述

引入依赖
配置公有vuex
配置vuex的配置
页面引入使用

引入依赖

npm install vuex@next --save

配置公有vuex

import './assets/main.css'import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './axios/store'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'const app = createApp(App)app.use(router)
app.use(store)
app.use(ElementPlus)app.mount('#app')

配置vuex的配置

import { createStore } from 'vuex'const store = createStore({state: {token: '',user: {}},mutations: {token(state, token) {state.token = token;},user(state, user) {state.user = user;}},getters: {getToken(state) {return state.user.token;},getUser(state) {return state.user;}}
})export default store;

页面应用


<template><div>{{ 1 + $store.state.token }} <!-- 使用计算属性 token --></div><Text></Text>
</template><script setup>
import Text from './views/test.vue';
import { onMounted, computed } from 'vue';
import { useStore } from 'vuex'// 在组件挂载时提交 token
onMounted(() => {store.commit('token', "fdsfdssfdsfdsfd");console.log(store.state.token);
});
</script>
<style scoped></style>
<template lang=""><div>{{2+ temp}}</div>
</template>
<script setup>
import { onMounted, computed, ref } from 'vue';
import { useStore } from 'vuex'
const store = useStore();
const temp = ref(0);
// 在组件挂载时提交 token
onMounted(() => {store.commit('token', "f尽快六角恐龙都结束了飞机到是覅sfd");console.log(store.state.token);temp.value = store.state.token;
});
</script>
<style lang=""></style>

结果：
