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

Copy after login

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

import VueI18n from &#39;vue-i18n&#39;

Vue.use(VueI18n) ;

const i18n = new VueI18n({
  locale: &#39;zh-CN&#39;,  // 语言标识, 通过切换locale的值来实现语言切换,this.$i18n.locale 
  messages: {
   &#39;zh-CN&#39;: require(&#39;./common/lang/zh&#39;),  // 中文语言包
   &#39;en-US&#39;: require(&#39;./common/lang/en&#39;)  // 英文语言包
  }
})

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

Copy after login

3. Corresponding language package

zh. js Chinese language package:

export const lang = {
 homeOverview:&#39;首页概览&#39;,
 firmOverview:&#39;公司概述&#39;,
 firmReports:&#39;财务报表&#39;,
 firmAppendix:&#39;更多附录&#39;,
 firmIndex:&#39;主要财务指标&#39;,
 firmAnalysis:&#39;对比分析&#39;,
 firmNews:&#39;新闻事件档案&#39;,
 firmOther:&#39;其他功能&#39;,
}

Copy after login

en.js English language package:

export const lang = {
 homeOverview:&#39;Home overview&#39;,
 firmOverview:&#39;firmOverview&#39;,
 firmReports:&#39;firmReports&#39;,
 firmAppendix:&#39;firmAppendix&#39;,
 firmIndex:&#39;firmIndex&#39;,
 firmAnalysis:&#39;firmAnalysis&#39;,
 firmNews:&#39;firmNews&#39;,
 firmOther:&#39;firmOther&#39;
}

Copy after login

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>

Copy after login

changeLangEvent() {
  console.log(&#39;changeLangEvent&#39;);
  this.$confirm(&#39;确定切换语言吗?&#39;, &#39;提示&#39;, {
   confirmButtonText: &#39;确定&#39;,
   cancelButtonText: &#39;取消&#39;,
   type: &#39;warning&#39;
  }).then(() => {
   if ( this.$i18n.locale === &#39;zh-CN&#39; ) {
    this.$i18n.locale = &#39;en-US&#39;;//关键语句
    console.log(&#39;en-US&#39;)
   }else {
    this.$i18n.locale = &#39;zh-CN&#39;;//关键语句
    console.log(&#39;zh-CN&#39;)
   }
  }).catch(() => {
   console.log(&#39;catch&#39;);
   this.$message({
    type: &#39;info&#39;,
   });
  });
 }

Copy after login

5. Template rendering

Static rendering:

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

Copy after login

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);
  }
}

Copy after login
