vue uses vue-i18n to implement internationalization code

This article mainly introduces the implementation code of vue using vue-i18n to achieve internationalization. Now I will share it with you and give you a reference.

Requirements

Company projects need to be internationalized, click the button to switch Chinese/English

1. Installation

npm install vue-i18n --save

2. Inject into the vue instance and implement calling api and template syntax in the project

import VueI18n from 'vue-i18n'

Vue.use(VueI18n) ;

const i18n = new VueI18n({
  locale: 'zh-CN',  // 语言标识, 通过切换locale的值来实现语言切换,this.$i18n.locale 
  messages: {
   'zh-CN': require('./common/lang/zh'),  // 中文语言包
   'en-US': require('./common/lang/en')  // 英文语言包
  }
})

new Vue({
 el: '#app',
 i18n, // 最后
 router,
 template: &#39;<App/>&#39;,
 components: { App }
})

3. Corresponding language package

zh. js Chinese language package:

export const lang = {
 homeOverview:'首页概览',
 firmOverview:'公司概述',
 firmReports:'财务报表',
 firmAppendix:'更多附录',
 firmIndex:'主要财务指标',
 firmAnalysis:'对比分析',
 firmNews:'新闻事件档案',
 firmOther:'其他功能',
}

en.js English language package:

export const lang = {
 homeOverview:'Home overview',
 firmOverview:'firmOverview',
 firmReports:'firmReports',
 firmAppendix:'firmAppendix',
 firmIndex:'firmIndex',
 firmAnalysis:'firmAnalysis',
 firmNews:'firmNews',
 firmOther:'firmOther'
}

4. Button control to switch language

this.$i18n.locale , when you assign the value to 'zh-CN', the navigation bar becomes Chinese; when the value is assigned to 'en-US', it becomes English:

<p class="top_btn" @click="changeLangEvent">中文</p>

changeLangEvent() {
  console.log('changeLangEvent');
  this.$confirm('确定切换语言吗?', '提示', {
   confirmButtonText: '确定',
   cancelButtonText: '取消',
   type: 'warning'
  }).then(() => {
   if ( this.$i18n.locale === 'zh-CN' ) {
    this.$i18n.locale = 'en-US';//关键语句
    console.log('en-US')
   }else {
    this.$i18n.locale = 'zh-CN';//关键语句
    console.log('zh-CN')
   }
  }).catch(() => {
   console.log('catch');
   this.$message({
    type: 'info',
   });
  });
 }

5. Template rendering

Static rendering:

<span v-text="$t(&#39;lang .homeOverview&#39;)"></span>
<span>{{$t(&#39;lang .homeOverview&#39;)}}</span>

If it is element-ui, add a colon in front of what you want to translate

For example: label="user Name" will be changed to: label="$t('order.userName')"

Dynamic rendering:

<span class="el-dropdown-link">{{navCompany}}</span>
 computed:{
   navCompany:function(){
    if(this.nav_company){
     let str = &#39;lang&#39;+this.nav_company;
     return this.$t(str);
    }
   }
},
    
 <el-submenu
      v-for="(value, title1, one) in navList"
      :key="one+1"
      :index="(one+1).toString()">

   <template slot="title">
    <router-link :to="linkList[title1]">{{ getTitle(title1) }}</router-link>
   </template>
       
</el-submenu>

methods: {
  getTitle(title){
    let str = &#39;lang.&#39;+title;
    return this.$t(str);
  }
}

The above is what I compiled for everyone, I hope It will be helpful to everyone in the future.
