有關多國語言的相關測試記錄

網頁版

會使用網頁來轉換json到excel

tw.json的結構

{
  "menu": {
    "home": "首頁",
    "feature": {
      "name": "功能模組",
      "form": "表單"
    },
    "language": "語言",
    "languageList": {
      "taiwanese": "繁體中文",
      "english": "English"
    }
  },
  "error": {
    "require": "{{itemName}}為必埴欄位"
  },
  "enum": {
    "gender": "男"
  },
  "validationMessages": {
    "email": {
      "required": "郵箱必須輸入",
      "pattern": "請輸入正確的郵箱地址"
    }
  }
}

有找到相關的程式碼，可以將json物件轉成key和value

npm install flat
npm install @types/flat --save-dev

將上面的json檔轉成

{
menu_home: "首頁", 
menu_feature_name: "功能模組", 
menu_feature_form: "表單", 
menu_language: "語言", 
menu_languageList_taiwanese: "繁體中文", 
…}

用法

import { flatten } from 'flat';
//...
  twjson = {
    "menu": {
      "home": "首頁",
      "feature": {
        "name": "功能模組",
        "form": "表單"
      },
      "language": "語言",
      "languageList": {
        "taiwanese": "繁體中文",
        "english": "English"
      }
    },
    "validationMessages": {
      "email": {
        "required": "郵箱必須輸入",
        "pattern": "請輸入正確的郵箱地址"
      }
    }
  };
  //...
 
    //console.log(flatten);
    let flatjson = flatten.flatten(this.twjson, { delimiter: '_' });
    console.log(flatjson);

下載檔案測試

npm install file-saver --save
npm install @types/file-saver --save-dev

程式碼

  testDownloadJson() {
    // var blob = new Blob(["Hello, world!"], { type: "text/plain;charset=utf-8" });
    // saveAs(blob, "hello world.txt");
    var jsonse = JSON.stringify(this.twjson);
    var blob = new Blob([jsonse], { type: "application/json" });
    saveAs(blob, "tw.json");
    saveAs(blob, "en.json");
  }

讀取xlsx

npm install xlsx

excel的結構

Key	Comment	en	tw
menu_home	首頁	home	首頁
menu_feature_name	功能模組	module	功能模組
menu_feature_form	表單	form	表單
menu_language	語言	language	語言
menu_languageList_taiwanese	繁體中文	繁體中文	繁體中文
menu_languageList_english	english	english	english
error_require	{{itemName}}為必埴欄位	{{itemName}} is require	{{itemName}}為必埴欄位
enum_gender	男	man	男
validationMessages_email_required	郵箱必須輸入	email is require	郵箱必須輸入
validationMessages_email_pattern	請輸入正確的郵箱地址	email had problem	請輸入正確的郵箱地址

加入多國語系的模組

npm install @ngx-translate/core --save
npm install @ngx-translate/http-loader --save

模組impot

import {TranslateModule} from '@ngx-translate/core';
import {HttpClientModule, HttpClient} from '@angular/common/http';
import {TranslateModule, TranslateLoader} from '@ngx-translate/core';
import {TranslateHttpLoader} from '@ngx-translate/http-loader';

// AoT requires an exported function for factories
export function HttpLoaderFactory(http: HttpClient) {
    return new TranslateHttpLoader(http);
}

imports: [
        .....
         HttpClientModule,
    TranslateModule.forRoot({
      loader: {
          provide: TranslateLoader,
          useFactory: HttpLoaderFactory,
          deps: [HttpClient]
      }
  })
        .....
    ],

使用預設的 loader來讀取多國語言檔這樣就會載入transModule，此設定翻譯檔預設會抓網站底下的i18n目錄，如果你要自訂翻譯檔的路徑可以改由以下設定:

export function createTranslateLoader(http: HttpClient) {
    return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}

使用多國語系在你的元件裏

記得要import service

import {TranslateService} from '@ngx-translate/core';
