1、首先安装插件vue-i18n
| 1 |
npm install vue-i18n --save-dev
|
2、创建文件
en.ts 文件内容
| 1 2 3 4 5 6 7 8 |
module.exports = {
language: {
name: '英文',
},
about: {
title: 'I am English',
},
};
|
zh.ts 文件内容
| 1 2 3 4 5 6 7 8 |
module.exports = {
language: {
name: '中文',
},
about: {
title: '我是中文',
},
};
|
index.ts
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
// 中英文切换
import Vue from 'vue';
import VueI18n from 'vue-i18n';
Vue.use(VueI18n);
const i18n = new VueI18n({
locale: localStorage.getItem('languageStorage') || 'zh',
messages: {
'zh': require('./zh'),
'en': require('./en'),
},
});
export default i18n;
|
3、在 mian.ts 引入i18n
| 1 2 3 4 5 6 7 8 |
import i18n from './components/language/index';
new Vue({
router,
store,
i18n,
render: (h) => h(App),
}).$mount('#app');

<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
@Component
export default class About extends Vue {
public language: string = localStorage.getItem('languageStorage') || 'zh';
private setLanguage(val: string) {
localStorage.setItem('languageStorage', val);
this.language = val;
this.$i18n.locale = val;
}
