How to change vue dynamic menu to Chinese

Vue is an excellent front-end framework that can help developers easily build high-quality web applications. Among them, Vue dynamic menu is a very important component, which allows us to dynamically generate different menu items and flexibly manage these items. In some scenarios, we need to use Vue dynamic menu to generate Chinese menu. This article will introduce how to implement this function.

Basic knowledge of Vue dynamic menu

In Vue, we can use Router to generate menus. Router is a core component in Vue that allows us to build single page applications. The router can not only help us implement functions such as page jumps and access control, but also generate dynamic menus.

In order to generate a basic menu, we need to use Vue’s router component. The following is a simple Vue router example that is used to implement a basic dynamic menu:

import Vue from 'vue' import VueRouter from 'vue-router' Vue.use(VueRouter) const routes = [ { path: '/', name: 'Home', component: () => import('@/views/Home.vue') }, { path: '/about', name: 'About', component: () => import('@/views/About.vue') } ] const router = new VueRouter({ routes }) export default router

In this router example, we define two pages named Home and About. These pages will be specified by routes in the router. By calling the router.push() method, we can dynamically jump to these pages.

Dynamicly generate Chinese menu

In order to generate a Chinese menu in Vue, we need to make some modifications on the router. First, we need to introduce the Vue-i18n library, which is an internationalization plug-in for Vue. Vue-i18n can help us manage text in different languages.

Here's how to use Vue-i18n in Vue:

1. Install Vue-i18n:

npm install vue-i18n

2. Create Vue- i18n instance:

import Vue from 'vue' import VueI18n from 'vue-i18n' Vue.use(VueI18n) const messages = { 'en': { menu: { home: 'Home', about: 'About' } }, 'zh': { menu: { home: '首页', about: '关于我们' } } } const i18n = new VueI18n({ locale: 'zh', // 语言环境 messages: messages // 文本信息 }) export default i18n

In this example, we create a Vue-i18n instance named i18n. We also define the messages object and use it to manage the names of Chinese and English menus.

3. Using Vue-i18n in Vue router:

import Vue from 'vue' import VueRouter from 'vue-router' import i18n from './i18n' Vue.use(VueRouter) const routes = [ { path: '/', name: 'Home', component: () => import('@/views/Home.vue') }, { path: '/about', name: 'About', component: () => import('@/views/About.vue') } ] const router = new VueRouter({ routes }) // 修改路由器菜单名称 router.beforeEach((to, from, next) => { document.title = to.meta.title let language = localStorage.getItem('language') || 'en' i18n.locale = language next() }) export default router

In this example, we call the beforeEach() function on the Vue router and use it to modify the router Menu name. We use localStorage to manage the current language selection. We also called the i18n.locale method to set the current language to the local language.

In this way, we can easily generate Chinese menus in Vue dynamic menus.
