vue中自定义设置多语言，并且运行js脚本自动生成多语言文件

在项目中需要进行多个国家语言的切换时，可以用到下面方法其中一个

一、自定义设置多语言

方法一:

可以自己编写一个设置多语言文件

在项目新建js文件，命名为：language.js，代码如下

// language.js 文档
let languagePage = {
  CN: {
    frame_rules: "规则",
    frame_remark: "虚位拟待",
  },
  EN: {
    frame_rules: "Rules",
    frame_remark: "Vacant position",
  },
  IN: {
    frame_rules: "Aturan",
    frame_remark: "Posisi Kosong",
  },
  VI: {
    frame_rules: "Quy tắc",
    frame_remark: "Vị trí Trống",
  },
  MS: {
    frame_rules: "Peraturan",
    frame_remark: "Jawatan Kosong",
  },
  TH: {
    frame_rules: "กฎ",
    frame_remark: "ตำแหน่งว่าง",
  },
  HI: {
    frame_rules: "กฎ",
    frame_remark: "खाली पद",
  },
};
export const getLangue = () => {
  // 获取我们设置存放在浏览器的localStorage 的语言类型
  let { language } =
    JSON.parse(window.localStorage.getItem("userInfo")) || {};
  // if (language == "ar") {
  //   // 阿拉伯语 展示顺序会相反，设置反向，使语言展示正常
  //   document.documentElement.setAttribute("dir", "rtl");
  //   // document.getElementById("app") &&
  //   //   document.getElementById("app").classList.add("ar");
  // }

  // zh  中文
  // en 英文
  // in  印尼
  // vi  越南
  // ms 马拉西亚
  // th  泰语
  // hi  印度语
  // ar 阿拉伯语

  let list = {
    in: "IN",
    id: "IN",
    zh: "CN",
    ms: "MS",
    vi: "VI",
    th: "TH",
    hi: "HI",
  };
  //假设能读取到浏览器设置的语言，就使用该语言 ，假设没有设置到浏览器任何语言类型，就默认使用英文
  if (list[language]) return languagePage[list[language]];
  return languagePage.EN;
};

在组件中使用多语言：

<template>
  <div>
    <!-- 使用多语言 -->
    <div>{{ language.frame_rules }}</div>
  </div>
</template>
<script>
// 在需要的组件引入多语言文件
import { getLangue } from "@/utils/language.js";

export default {
  data() {
    return {
      language: getLangue(), //赋值多语言
    };
  },
  mounted() {},
  computed: {},
  methods: {},
};
</script>
<style lang="scss" scoped></style>

设置类型语言：

你可以在app.vue的生命周期设置

//vue的生命周期mounted设置语言为中文
mounted() {
    const langType = JSON.stringify({ language: "zh" });
    window.localStorage.setItem("userInfo", langType);
},

当然，你可以写选择器，让用户选择对应的语言，然后强制刷新浏览器后便生效了

 const langType = JSON.stringify({ language: "zh" });
 window.localStorage.setItem("userInfo", langType);
 window.location.reload(); //设置完语言后 强制刷新浏览器才生效

方法二：使用使用vue-i18n 库，提示，下面展示是vue3中使用为例子

官方文档介绍：介绍 | Vue I18n

使用npm导入vue-i18n

npm i vue-i18n@next  --save

1、创建i18n所需文件夹（这里最好放置src下）

在src下建文件夹lang，在文件夹下新建文档 en.ts 和zh.ts 文档里面内容如下

en.ts文档：

// en.js文档

//键值命名一定要和zh.ts 一一对应 ，键值的写法可用双引号，例如："OP_check"，也可不用。例如：home

// 英文
const en = {
  "OP_check": "CHECK",
  home: "Home",
};
export default en;

zh.ts文档：

// zh.js文档

// 中文
const zh = {
  "OP_check": "查看",
  home: "主页",
};
export default zh;

2.在文件夹lang新建文档命名 index.ts

index.ts文档：

import en from "./en"; // 英文
import zh from "./zh"; // 中文

//导出所有翻译内容
export default {
  en,
  zh,
};

3、在文件夹lang新建文档命名 i18n.ts

i18n.ts文档

import { createApp } from "vue";
//这里注意引入的App.vue文件路径，确保文件成功被引进来
import App from "../App.vue";

import { createI18n } from "vue-i18n";
import messages from "./index";

const app = createApp(App);
const language = (navigator.language || "en").toLocaleLowerCase(); // 这是获取浏览器的语言

if (!localStorage.getItem("lang")) {
  localStorage.setItem("lang", "en"); //设置默认语言为英文
}

const i18n = createI18n({
  legacy: false, //处理报错Uncaught (in promise) SyntaxError: Not available in legacy mode (at message-compiler.esm-bundler.js:54:19)
  locale: localStorage.getItem("lang") || language.split("-")[0] || "en", //注意locale属性！ 首先从缓存里拿，没有的话就用浏览器语言，
  fallbackLocale: "en", // 设置备用语言
  messages,
});

export default function (app: any) {
  app.use(i18n);
}

4、在vue的mian文件，全局注入多语言

主要代码如下；

import i18n from "@/lang/i18n"; //导入多语言

app.use(i18n); //全局注入多语言

5、在项目中使用多语言

在dom元素上直接使用vue-i18n如下

<template>
  <!-- 在 dom中使用vue-i18n-->
  <div>{{ $t("home") }}</div>
</template>

在<script>脚本中使用vue-i18n如下

<template>
  <!-- 在 dom中使用vue-i18n-->
  <div>{{ $t("home") }}</div>
</template>
<script lang="ts" setup>
import { ref } from "vue";
import { useI18n } from "vue-i18n"; //引入vue-i18n
const { t } = useI18n(); // 使用多语言关键字 t ——> vue-i18内置关键字，不可改写名字
const title = ref(t("OP_check"));  //在js代码中使用vue-i18n 这里的title === "CHECK"
</script>
<style scoped lang="scss"></style>

6、使用vue-i18n设置语言

<template>
  <!-- 在 dom中使用vue-i18n-->
  <div>{{ $t("home") }}</div>
</template>
<script lang="ts" setup>
import { ref } from "vue";
import { useI18n } from "vue-i18n"; //引入vue-i18n
const { locale } = useI18n(); // 使用多语言关键字 locale ——> vue-i18内置关键字，不可改写名字
const changLanguage = (e: any) => {
// 设置语言,其中locale是vue-i18内置设置语言的固定方法；改变locale的值就是改变语言类型了
  if (Number(e) === 1) {
    locale.value = "en";
    localStorage.setItem("lang", "en");
  } else {
    locale.value = "zh";
    localStorage.setItem("lang", "zh");
  }
  window.location.reload(); // 设置语言完成后，强制刷新浏览器，效果更换好
};
</script>
<style scoped lang="scss"></style>

上面设置多语言需要一个个复制粘贴进去，在开发工作的过程中很麻烦，是非常浪费时间的无脑操作，下面我们通过脚本，自动生成多语言文档，

二、运行js脚本自动生成多语言文件

1、在src同级目录下，新建目录命名 tools

2.在tools 下新建文件夹命名lang

3、在lang文件夹下，新建文档命名：package-lock.json

package-lock.json文档代码如下

5、在lang文件夹下，新建文档命名：app.js

app.js文档代码如下

import { createRequire } from "module";

const require = createRequire(import.meta.url);
var path = require("path");
var fs = require("fs");
var xlsx = require("node-xlsx").default;
const TABLE_KEY = "lang_key";
var _OutputPath = "../../src/lang/";

function isExits(path) {
  try {
    fs.statSync(path);
    return true;
  } catch (e) {
    return false;
  }
}

function loopSheet(data) {
  if (data) {
    let _myData = {};
    let _myIndex = {};
    //解析表头
    while (data.length > 0) {
      const _rData = data.shift();
      if (_rData.length > 0) {
        if (_rData[0] == TABLE_KEY) {
          let len = _rData.length > 4 ? 4 : _rData.length; // 这里数字表示要生产几个文件, 3表示生产两种多语言，假设4，便是生产3种多语言
          for (let index = 1; index < len; index++) {
            const element = _rData[index];
            _myData[element] = {};
            _myIndex[element] = index;
          }
          break;
        }
      }
    }
    console.log("====================================");
    console.log("语言结构:", _myIndex);
    console.log("语言结构:", _myData);
    console.log("====================================");
    let _keys1 = Object.keys(_myData);
    let _keys2 = Object.keys(_myIndex);
    //确保结构是对称的
    if (
      _keys1.length > 0 &&
      _keys2.length > 0 &&
      _keys1.length == _keys2.length
    ) {
      //TODO:做数据的遍历、存储到需要的位置
      for (let row = 0; row < data.length; row++) {
        const _rData = data[row];
        for (const key in _myIndex) {
          if (_myIndex.hasOwnProperty(key)) {
            const _keyIndex = _myIndex[key];
            _myData[key][_rData[0]] = _rData[_keyIndex];
          }
        }
      }
    }
    console.log("====================================");
    console.log("数据汇总:", _myData);
    console.log("====================================");

    //写出文件
    for (const key in _myData) {
      if (_myData.hasOwnProperty(key)) {
        const _sheetData = _myData[key];
        let _file = _OutputPath + key + ".ts";
        let str =
          "const " +
          key +
          " = " +
          JSON.stringify(_sheetData, null, "\t") +
          ";\n";
        str += "export default " + key + ";";

        fs.writeFile(_file, str, function (err) {
          if (err) {
            res.status(500).send("Server is error...");
          }
        });
      }
    }
  }
}

function parse(path) {
  let _isFile = isExits(path);
  if (_isFile) {
    // var arr = path.split("/");
    // delete arr[arr.length - 1];
    // _OutputPath = arr.join("/");
    console.log("====================================");
    console.log("_OutputPath:", _OutputPath);
    console.log("====================================");
    const workSheetsFromFile = xlsx.parse(path);
    if (workSheetsFromFile) {
      for (let index = 0; index < workSheetsFromFile.length; index++) {
        const sheet = workSheetsFromFile[index];
        console.log("====================================");
        console.log(sheet.name);
        console.log("====================================");
        loopSheet(sheet.data);
      }
    } else {
      console.log("====================================");
      console.log("文件出错！");
      console.log("====================================");
    }
  } else {
    console.log("====================================");
    console.log("文件不存在！");
    console.log("====================================");
  }
}

parse(process.argv[2]);

6、确认在src目录下有一个文件夹名字为lang 如下图

没有就必须创建文件夹名字为lang
