1、安装

npm install vue-i18n --save

2、创建存放语言包和i18n入口文件

  a、在src下创建i18n目录

  b、在src/i18n/创建i18n.js  (入口)

  c、在src/i18n/创建langs目录存放语言包

  d、在src/i18n/langs/创建en.js(英文) 和 zh.js(中文)两个文件

  VueJS 使用i18n做国际化切换中英文-LMLPHP

i18n.js

i18n.js

 import Vue from 'vue'
import locale from 'element-ui/lib/locale';
import VueI18n from 'vue-i18n'
//import messages from './langs' //自定义中英文包
import zh from './langs/zh'
import en from './langs/en' //element 中英文包
import enLocale from 'element-ui/lib/locale/lang/en'
import zhLocale from 'element-ui/lib/locale/lang/zh-CN'
Vue.use(VueI18n) const messages = {
en: Object.assign(en, enLocale),
zh: Object.assign(zh, zhLocale)
}
//从localStorage中拿到用户的语言选择,如果没有,那默认中文。
/*const i18n = new VueI18n({
locale: localStorage.lang || 'zh',
messages,
})*/
const i18n = new VueI18n({
locale: localStorage.getItem('locale') || 'en',
messages
})
locale.i18n((key, value) => i18n.t(key, value)) //为了实现element插件的多语言切换
console.log('%c当前缓存语言是:'+(localStorage.getItem('locale')=='en'?'English':'中文')+'','color:#fff;background:green;padding:4px;border-radius:5px');
export default i18n

en.js

 import enLocale from 'element-ui/lib/locale/lang/en'
const en = {

export default en;

英文语言包

zh.js

 const cn = {

} export default cn;

中文语言包

3、main.js中引用src/i18n/i18n.js入口文件

 //引入vue 和 router模块
import Vue from 'vue'
import App from './App'
import router from './router'
//引入element-ui
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css' import i18n from './i18n/i18n' Vue.use(ElementUI)
Vue.config.productionTip = false let gvm = new Vue({
el: '#app',
router,
i18n,
components: { App },
template: '<App/>'
})

main.js

4、找一个vue文件(header.vue)

a、创建模板--> 下拉组件,有中英文两个选项

 <template>
<div class="navbar">
<span>Concept Tree Engineer</span>
<p></p>
<el-select style="width: 87px;" size="mini" v-model="value" @change="toggleLang" placeholder="请选择">
<el-option
v-for="item in options"
:key="item.value"
:label="item.label"
:value="item.value"
>
</el-option>
</el-select>
</div>
</template>

模板代码

b、创建script (配置默认为英文、配置下拉选择切换语言、配置首次进入获取用户缓存的语言进行显示)

 <script>
export default {
name: 'Navbar',
data() {
return {
options: [{
value: 'en',
label: 'English'
}, {
value: 'zh',
label: '中文'
}],
value: 'en'
}
},
mounted(){
//用户每次刷新页面都判断 是否缓存过 语言,缓存过的话 选择其中显示的应该是缓存的语言
localStorage.getItem('locale') == 'en' ? this.value = 'en' : this.value = 'zh'
},
methods: {
toggleLang(lang) {
const loading = this.$loading({
lock: true,
text: this.$t("element.loadingText"),
spinner: 'el-icon-loading',
background: 'rgba(0, 0, 0, 0.7)'
});
setTimeout(function(){
loading.close();
},600)
if(lang == 'zh') {
localStorage.setItem('locale', 'zh')
this.$i18n.locale = localStorage.getItem('locale')
} else if(lang == 'en') {
localStorage.setItem('locale', 'en')
this.$i18n.locale = localStorage.getItem('locale')
}
}
}
}
</script>

配置代码

总结:

  1、this.options 配置的是下拉框显示的option 和 选择后的value

     this.value 是用户选择后双向绑定的 options.[index].value

  2、toggleLang(lang):用户选择后,调用toggleLang方法,判断是 选择的是英文 还是 中文。

     如果是中文:将中文缓存起来,并且赋值给全局的i18n对象的locale。完成切换。

     如果不是:将英文缓存起来,并且赋值给全局的i18n对象的locale。完成切换。

  3、mounted():vue生命周期钩子挂载完成后,获取缓存中的语言代码,绑定给下拉的vue。作用是,根据缓存的语言代码,设置下拉选项默认显示什么。

最后:展示成果
