vue3.0 + ts + element-plus + i18n 中英文切换

1、安装i18n:

npm install vue-i18n@next 

vue3.0 + ts + element-plus + i18n 中英文切换

 

 

 

2、main.ts 引入:

import { createApp } from 'vue';
import App from './App.vue';
import router from './router';
import store from './store';
import ElementPlus from 'element-plus';
import 'element-plus/lib/theme-chalk/index.css';
import ZhLocale from 'element-plus/lib/locale/lang/zh-cn'; // 中文
import EhLocale from 'element-plus/lib/locale/lang/en'; // 英文
import I18n from "@/lang/index"; //引入i18n组件

let locale = '';
//控制 element-plus 组件语言 if(I18n.global.fallbackLocale == 'zh') { locale = ZhLocale as unknown as string; } else { locale = EhLocale as unknown as string; } createApp(App).use(store).use(router).use(ElementPlus, { locale }).use(I18n).mount('#app');

3、src 新建 lang 文件:

index.js:

import { createI18n } from 'vue-i18n'
const i18n = createI18n({
    locale: localStorage.getItem('lang') || 'zh',        //默认显示的语言 
    messages: {
        zh: require('./zh.js'),    //引入语言文件
        en: require('./en.js')
    }
})
export default i18n;

zh.js:

module.exports = {
    header_menu: {
        login:'登录',
        register:'注册',
        logout:'退出登录',
    }
}

en.js:

module.exports = {
    header_menu: {
        login: 'Login',
        register: 'Register',
        logout: 'Log out',
    }
}

4、中英文切换组件:

<el-dropdown trigger="click" @command="handleSetLanguage" class="languages">
  <div style="font-size: 15px;">
    <span>{{langName}}</span>
    <i class="el-icon-arrow-down el-icon--right"/>
  </div>
  <template #dropdown>
    <el-dropdown-menu>
      <el-dropdown-item :disabled="language==='zh'" command="zh">中文</el-dropdown-item>
      <el-dropdown-item :disabled="language==='en'" command="en">English</el-dropdown-item>
    </el-dropdown-menu>
  </template>
</el-dropdown>

//  setup:
const langName = ref('');
const language = ref('');

// 切换事件:
const handleSetLanguage = (lang: string) => {
  if(lang === 'zh') {
    langName.value = '中文';
  } else {
    langName.value = 'English';
  }
  language.value = lang;
  localStorage.setItem('lang', lang);
  ElMessage.success('语言切换成功');
  location.reload();
};

//页面加载判断语言
onMounted(()=>{
  if(localStorage.getItem('lang') == undefined) {      langName.value = '中文';      language.value = 'zh';   }   if(localStorage.getItem('lang') == 'zh') {     langName.value = '中文';     language.value = 'zh';   } else {     langName.value = 'English';      language.value = 'en';   } })
