一:使用i18n
1、在src目录下建立文件夹:lang
2、en.js:
const zh = { // layout commons: { xiaoai: 'Ai.', admin: 'Admin', editor: 'Editor', quit: 'Sign Out', hi: 'Hi', index: 'Dashboard', userManage: 'Users', share: 'Share', infoManage: 'Infos', infoShow: 'InfoShow', infoShow1: 'InfoShow1', infoShow2: 'InfoShow2', infoShow3: 'InfoShow3', infoShow4: 'InfoShow4', infoShow5: 'InfoShow5', infoModify: 'InfoModify', infoModify1: 'InfoModify1', infoModify2: 'InfoModify2', infoModify3: 'InfoModify3', fundManage: 'Money', fundList: 'MoneyList', chinaTabsList: 'AreaList', fundData: 'FundData', fundPosition: 'FundPosition', typePosition: 'TypePosition', incomePayPosition: 'IncomePayPosition', permission: 'Permission', pagePer: 'PagePermission', directivePer: 'DirectivePermission', errorPage: 'ErrorPage', page401: '401', page404: '404', wechatNumber: 'wechat' }, index: { yearLoss: 'Year Loss', yearProfit: 'Year Profit', potentialInvestor: 'Potential Investor', intentionInvestor: 'Intention Investor', waitExamineInvestor: 'Wait Examine Investor', examiningInvestor: 'Examining Investor', tenMillion: 'Ten Million', person: 'P' } }; export default zh;
3、zh.js:
const zh = { // layout commons: { xiaoai: '小爱', admin: '管理员', editor: '赵晓编', quit: '退出', hi: '您好', index: '首页', userManage: '用户管理', share: '分享功能', infoManage: '信息管理', infoShow: '个人信息', infoShow1: '个人信息子菜单1', infoShow2: '个人信息子菜单2', infoShow3: '个人信息子菜单3', infoShow4: '个人信息子菜单4', infoShow5: '个人信息子菜单5', infoModify: '修改信息', infoModify1: '修改信息子菜单1', infoModify2: '修改信息子菜单2', infoModify3: '修改信息子菜单3', fundManage: '资金管理', fundList: '资金流水', chinaTabsList: '区域投资', fundData: '资金数据', fundPosition: '投资分布', typePosition: '项目分布', incomePayPosition: '收支分布', permission: '权限设置', pagePer: '页面权限', directivePer: '按钮权限', errorPage: '错误页面', page401: '401', page404: '404', wechatNumber: '微信号' }, index: { yearLoss: '年度总盈亏', yearProfit: '年度收益率', potentialInvestor: '潜在投资人', intentionInvestor: '意向投资人', waitExamineInvestor: '待审投资人', examiningInvestor: '审核中投资人', tenMillion: '千万元', person: '人' } }; export default zh;
4、index.js:
// 引入i18n国家化插件 import { getToken } from '@/utils/auth'; import Vue from 'vue'; import VueI18n from 'vue-i18n'; import enLocale from './en'; import zhLocale from './zh'; // eslint-disable-next-line no-unused-expressions process.env.NODE_ENV === 'development' ? Vue.use(VueI18n) : null; // 注册i18n实例并引入语言文件,文件格式等下解析 console.log(getToken('lang')); const i18n = new VueI18n({ locale: getToken('lang') || 'zh', messages: { zh: { ...zhLocale }, en: { ...enLocale } } }); export default i18n;
locale: getToken('lang') || 'zh':查看是否存在token:lang,没有就默认语言为中文
5、main.js:
import Vue from 'vue'; import App from './App.vue'; import ElementUI from 'element-ui'; import 'element-ui/lib/theme-chalk/index.css'; import router from '@/router/index.js'; import '@/assets/iconfonts/iconfont.css'; import store from '@/store/index.js'; import '@/permission.js'; import '@/mock/index.js'; import i18n from '@/lang/index.js'; Vue.use(ElementUI); Vue.config.productionTip = false; new Vue({ router, store, i18n, // 便于可以直接在组件中通过this.$i18n使用,也可以按需引用 render: h => h(App) }).$mount('#app');
二:如何切换语言
如图:
headNav.vue组件中:
import { mapGetters } from 'vuex'; import TopMenu from './topMenu'; import { github } from '@/utils/env'; import wechatImg from '@/assets/img/wechat.jpg'; import qqImg from '@/assets/img/qq.png'; import chinaImg from '@/assets/img/china.svg'; import americaImg from '@/assets/img/america.svg'; import { getToken, setToken } from '@/utils/auth.js'; export default { components: { TopMenu }, data() { return { github: github, wechatImg: wechatImg, qqImg: qqImg, chinaImg: chinaImg, americaImg: americaImg,
// 如果存在token:langLogo,就取它,没有就默认为英文
langLogo: getToken('langLogo') || americaImg }; },
切换语言:
<el-submenu index="1" class="language"> <template slot="title"> <img :src="langLogo" /> </template> <el-menu-item index="1-1" @click="changeLocale('zh')"> <!-- <img :src="chinaImg" alt="中文" /> <span class="intro">中文</span>--> <img :src="chinaImg" alt="中文" :style="{ width: '20px', marginRight: '6px' }" /> <span class="intro">中文</span> </el-menu-item> <el-menu-item index="1-2" @click="changeLocale('en')"> <!-- <img :src="americaImg" alt="English" /> <span class="intro">English</span>--> <img :src="americaImg" alt="English" :style="{ width: '20px', marginRight: '6px' }" /> <span class="intro">English</span> </el-menu-item> </el-submenu>
changeLocale(type) { setToken('lang', type); this.$i18n.locale = type; if (type === 'en') { this.langLogo = americaImg; } else { this.langLogo = chinaImg; } setToken('langLogo', this.langLogo); }
