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.$i18n.locale
messages: {
'zh-CN': require('./common/lang/zh'), // 中文语言包
'en-US': require('./common/lang/en') // 英文语言包
}
})
new Vue({
el: '#app',
i18n, // 最后
router,
template: '<App/>',
components: { App }
})3. Corresponding language package
zh. js Chinese language package:
export const lang = {
homeOverview:'首页概览',
firmOverview:'公司概述',
firmReports:'财务报表',
firmAppendix:'更多附录',
firmIndex:'主要财务指标',
firmAnalysis:'对比分析',
firmNews:'新闻事件档案',
firmOther:'其他功能',
}en.js English language package:
export const lang = {
homeOverview:'Home overview',
firmOverview:'firmOverview',
firmReports:'firmReports',
firmAppendix:'firmAppendix',
firmIndex:'firmIndex',
firmAnalysis:'firmAnalysis',
firmNews:'firmNews',
firmOther:'firmOther'
}4. Button control to switch language
this.$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('lang .homeOverview')"></span>
<span>{{$t('lang .homeOverview')}}</span>If it is element-ui, add a colon in front of what you want to translate
For example: label="user Name" will be changed to: label="$t('order.userName')"
Dynamic rendering:
<span class="el-dropdown-link">{{navCompany}}</span>
computed:{
navCompany:function(){
if(this.nav_company){
let str = 'lang'+this.nav_company;
return this.$t(str);
}
}
},
<el-submenu
v-for="(value, title1, one) in navList"
:key="one+1"
:index="(one+1).toString()">
<template slot="title">
<router-link :to="linkList[title1]">{{ getTitle(title1) }}</router-link>
</template>
</el-submenu>
methods: {
getTitle(title){
let str = 'lang.'+title;
return this.$t(str);
}
}The above is what I compiled for everyone, I hope It will be helpful to everyone in the future.
