14-用户数据存储到vuex

引入 vuex

在 src 文件夹下面新建 store/index.ts

ts 复制代码

import { createStore } from 'vuex'
import { type App } from 'vue'

const store = createStore<{ menus: {}[] }>({
    state() {
        return {
            menus: []
        }
    },
    getters: {},
    mutations: {
        updateMenus(state, menus) {
            console.log('updateMenus--->', state, menus)
            state.menus = menus
        }
    },
    actions: {},
    modules: {}
})

export const initStore = (app: App<Element>) => {
    app.use(store)
}

报错

如果引入vuex ts报错，请参考这个

无法找到模块"vuex"的声明文件

使用

main.ts

ts 复制代码

import { createApp } from 'vue'
import App from './App.vue'
import { initRouter } from './router'
import { initStore } from './store'
// 导入 Element Plus 样式
import 'element-plus/dist/index.css'

const app = createApp(App);
// 初始化路由
initRouter(app);
// 初始化vuex
initStore(app);
app.mount('#app')

在 login.vue 登录后，将用户信息存储到vuex

html 复制代码

<template>
    <div class="login-rule-form">

另外将 menu 改成 menus
