根据选择动态加载i18n Angular语言环境 [英] Dynamically load i18n Angular locale depending on select

问题描述

我使用带有所有国家/地区列表的select，并使用外部json-File进行填充.在此文件中，我有一个i18n语言环境语言-国家/地区"的密钥，例如."zh-cn".

I use an select with a list of all countries, populating with an external json-File. In this File, I have a key for the i18n locale 'language - Country' for e.g. 'en-us'.

更新选择后，我得到了语言环境.有没有办法动态加载来自目录 https://code.angularjs的i18n angular.org/1.2.10/i18n/ angular-locale_XX-XX.js?谢谢您的提示

I get the locale after updating the select. Is there a way to dynamicall load the i18n angular, coming from the directory https://code.angularjs.org/1.2.10/i18n/ angular-locale_XX-XX.js ? Thank you for your tips

HTML

<select ng-change="updateCountry()" ng-disabled="!data.locations.countries.$resolved" ng-model="selectionCountry" ng-options="country.name for country in data.locations.countries"></select>

脚本

 .controller('MyCtrl', ['$scope','$filter', '$http', '$timeout', '$locale', function($scope, $filter, $http, $timeout, $locale) {

     $scope.data = {
    locations: {
      countries: []
    }
  };

  // set default Country
  $scope.data.locations.countries.$default = 'United States';
  $scope.data.locations.countries.$resolved = false;

  // Populate countries.json in Country Select
  $http.get('l10n/countries.json').success(function(countries) {
    $scope.data.locations.countries.length = 0;
    // actually filter is set to none. to activate choose for e.g. (countries, 'name')
    Array.prototype.push.apply($scope.data.locations.countries, $filter('orderBy')(countries, ''));
    $scope.selectionCountry || ($scope.selectionCountry = $filter('filter')($scope.data.locations.countries, {name: $scope.data.locations.countries.$default})[0]);
    $scope.data.locations.countries.$resolved = true; 
  });

// get the i18n locale for the selected option
$scope.updateCountry = function() {
var selFormat=$scope.selectionCountry.i18n;
   console.log(selFormat);
};

推荐答案

好.我找到了解决方案:

O.k. I got the solution:

var imported = document.createElement('script');
var fileImport = 'angular-locale_' + selFormat + '.js';
imported.src = 'https://code.angularjs.org/1.2.10/i18n/' + fileImport;
document.head.appendChild(imported);
