前端双语实现方案（VUE版）

一、封装一个lib包

结构如下

en.js

'use strict';

exports.__esModule = true;
exports.default = {
    sp: {
        input: {
            amountError: 'Incorrect amount format'
        },
        table: {
            total: 'Total:',
            selected: 'Selected:',
            tableNoData: 'No data',
            tableNoDataSubtext: 'Tip: Suggest to recheck your filter.',
            tableLoadingData: 'Searching...'
        },
        select: {
            placeholder: 'Select'
        },
        preview: {
            button: 'View'
        }
    }
};

zh-CN.js

'use strict';

exports.__esModule = true;
exports.default = {
    sp: {
        input: {
            amountError: '金额格式不正确'
        },
        table: {
            total: '共计：',
            selected: '已选择：',
            tableNoData: '暂无数据',
            tableNoDataSubtext: '提示：建议核实筛选条件',
            tableLoadingData: '搜索中...'
        },
        select: {
            placeholder: '请选择'
        },
        preview: {
            button: '查看'
        }
    }
};

index.js

'use strict';

exports.__esModule = true;
exports.i18n = exports.use = exports.t = undefined;

var _zhCN = require('./lang/zh-CN');

var _zhCN2 = _interopRequireDefault(_zhCN);

var _vue = require('vue');

var _vue2 = _interopRequireDefault(_vue);

var _deepmerge = require('deepmerge');

var _deepmerge2 = _interopRequireDefault(_deepmerge);

var _format = require('element-ui/lib/locale/format');

var _format2 = _interopRequireDefault(_format);

function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

var format = (0, _format2.default)(_vue2.default);
var lang = _zhCN2.default;
var merged = false;
var i18nHandler = function i18nHandler() {
  var vuei18n = Object.getPrototypeOf(this || _vue2.default).$t;
  if (typeof vuei18n === 'function' && !!_vue2.default.locale) {
    if (!merged) {
      merged = true;
      _vue2.default.locale(_vue2.default.config.lang, (0, _deepmerge2.default)(lang, _vue2.default.locale(_vue2.default.config.lang) || {}, { clone: true }));
    }
    return vuei18n.apply(this, arguments);
  }
};
var t = exports.t = function t(path, options) {
  var value = i18nHandler.apply(this, arguments);
  if (value !== null && value !== undefined) return value;

  var array = path.split('.');
  var current = lang;

  for (var i = 0, j = array.length; i < j; i++) {
    var property = array[i];
    value = current[property];
    if (i === j - 1) return format(value, options);
    if (!value) return '';
    current = value;
  }
  return '';
};

var use = exports.use = function use(l) {
  lang = l || lang;
};

var i18n = exports.i18n = function i18n(fn) {
  i18nHandler = fn || i18nHandler;
};

exports.default = { use: use, t: t, i18n: i18n };

二、封装i18n对象

结构如下

index.js

import Vue from 'vue';
import VueI18n from 'vue-i18n';
import elementLocale from 'element-ui/lib/locale';

import elementCnLocale from 'element-ui/lib/locale/lang/zh-CN'; // element-ui lang
import elementEnLocale from 'element-ui/lib/locale/lang/en'; // element-ui lang
import cnLocale from './lang/cn';
import enLocale from './lang/en';
import spuiEnLocale from 'lib/locale/lang/en';
import spuiCnLocale from 'lib/locale/lang/zh-CN';
import spuiLocale from 'lib/locale/index.js';

const messages = {
  en: {
    ...elementEnLocale,
    ...enLocale,
    ...spuiEnLocale

  },
  cn: {
    ...elementCnLocale,
    ...cnLocale,
    ...spuiCnLocale

  }
};

Vue.use(VueI18n);

const i18n = new VueI18n({
  locale: 'cn',
  fallbackLocale: 'cn',
  messages
});

// fix element-ui language switching issue.
elementLocale.i18n((key, value) => i18n.t(key, value));
spuiLocale.i18n(function(key, value) {
  return i18n.t(key, value);
});

export default i18n;

cn/index.js

      { value: '603', label: 'Something wrong with accessing permission. Suggest to sign in again.' },
    ],
    unknownError: 'Unknown error.'
  }
};

三、在VUE中引入 main.js

import i18n from './i18n';

const vue = new Vue({
  router,
  store,
  i18n,
  created() {
    injectBeyla();
  },
  mounted() {
    util.init();
  },
  render: h => h(App),
}).$mount('#app');

四、在页面中使用

  
  <ProblemDescription :title="$t(`workOrderInfo.yourLocalReceivingAccountNumber`)" />
  <el-button @click="goBack">{{ $t('workOrderInfo.return') }}</el-button>

 {
    prop: 'status',
    labelKey: 'workOrderInfo.workOrderStatus',
    minWidth: 130,
    render(h, row) {
      const type = setStatus(row.status, this.language) || '';
      return <div>
        {row.status == 'PROCESS' && <div style='color: rgba(251, 151, 1, 1);padding: 4px 12px;border-radius: 14px;background: rgba(255, 241, 215, 1);'>{type || '-'}</div>}
        {row.status == 'FINISHED' && <div style='color: rgba(0, 195, 82, 1);padding: 4px 12px;border-radius: 14px;background: rgba(230, 249, 239, 1);'>{type || '-'}</div>}
      </div>;
    }
  },
  

  import local from './local';

  const SCOPE_NAME = 'workOrderInfo';


  created() {
    if (!this.$i18n.getLocaleMessage('en')[SCOPE_NAME]) {
      this.$i18n.mergeLocaleMessage('en', local.en);
      this.$i18n.mergeLocaleMessage('cn', local.cn);
