javascript - ionic : How to make Angular Translate js working with Search Filter when language changed?

Question

Solved the issue. Solution is edited in this question. Thank you "praszyk".

我无法让 Angular Translate 与 Search Filter 一起工作。当语言为英语时，列表项可以照常用英语搜索。但是当语言是孟加拉语时，这些项目仍然可以用英语搜索，但不能用孟加拉语搜索。有什么解决办法吗？

<ion-list>
            <ion-item>
              <label class="item item-input">
                <i class="icon ion-search placeholder-icon"></i>
                <input type="text" ng-model="input.filterUser" placeholder="Search">
              </label>
            </ion-item>
              <ion-item class="item-avatar" ng-repeat="user in groups | filter:input.filterUser">
                <img src="{{user.avatar}}">           
                <h2>{{user.name | translate}}</h2>
                <p>{{user.fullname}}
                  {{user.email}}</p>       
              </ion-item>        
          </ion-list>

Controller

.controller('CreditCtrl', function($scope, $ionicConfig, $translate) {

  $scope.input = {};  
  $scope.groups = [
  {
  index: 1,
  index_start_at: 56,
  name:  "Bnd_Nilgiri",
  surname: "Hayes",
  fullname: "Grace Beatty",
  email: "francis@livingston.es",
  bool: false,
  avatar: "img/ionic.png"
  },
  {
  index: 2,
  index_start_at: 57,
  name: "Bnd_Nilachal",
  surname: "Shayes",
  fullname: "Srace Beatty",
  email: "shuvo@livingston.es",
  bool: false,
  avatar: "img/ionic.png"
  }
];



 angular.forEach($scope.groups, function(user, index){
      $translate(user.name, {user: user}).then(function(translated){
        $scope.groups[index].name = translated;
      });
    });

})

.config(function($stateProvider, $urlRouterProvider, $ionicConfigProvider, $translateProvider) {

 $translateProvider.translations('en', {
    Bnd_Nilgiri : 'Nilgiri Tourspot',
    Bnd_Nilachal : 'Nilachal Tourspot',
    Bnd_Bogalake : 'Bogalake Tourspot',    
  });
  $translateProvider.translations('de', {
    // Bandarban Tour Spots

    Bnd_Nilgiri : 'নিলগিরি ট্যুর স্পট',
    Bnd_Nilachal : 'নিলাচল ট্যুর স্পট',
    Bnd_Bogalake : 'বগালেক ট্যুর স্পট',
  });
  $translateProvider.preferredLanguage('en');

那是因为你的| translate 过滤器在 Angular 过滤器之后应用。

唯一可能的解决方案是事先转换数组 groups。 在将其应用于 groups 变量之前，您需要在 Controller 中使用 $translate 服务:

var en_translations =  {
    Bnd_Nilgiri : 'Nilgiri Tourspot',
    Bnd_Nilachal : 'Nilachal Tourspot',
    Bnd_Bogalake : 'Bogalake Tourspot',    
}

var de_translations = {
    Bnd_Nilgiri : 'নিলগিরি ট্যুর স্পট',
    Bnd_Nilachal : 'নিলাচল ট্যুর স্পট',
    Bnd_Bogalake : 'বগালেক ট্যুর স্পট',
};


var app = angular.module('myApp', ['pascalprecht.translate']);

app.config(['$translateProvider', function ($translateProvider) {
  // add translation table
  $translateProvider
    .translations('en', en_translations)
    .translations('de', de_translations)
    .preferredLanguage('de');
}]);

app.controller('Ctrl', ['$scope', '$translate', function ($scope, $translate) {
  // expose translation via `$translate` service
  $scope.groups =  [
    {
      index: 1,
      index_start_at: 56,
      name:  "Bnd_Nilgiri",
      surname: "Hayes",
      fullname: "Grace Beatty",
      email: "francis@livingston.es",
      bool: false,
      avatar: "img/ionic.png"
    },
    {
      index: 2,
      index_start_at: 57,
      name: "Bnd_Nilachal",
      surname: "Shayes",
      fullname: "Srace Beatty",
      email: "shuvo@livingston.es",
      bool: false,
      avatar: "img/ionic.png"
    }
  ];
  angular.forEach($scope.groups, function(user, index){
    $translate(user.name, {user: user}).then(function(translated){
      $scope.groups[index].name = translated;
    });
  });

}]);

我没有测试代码，但这是我想象的滚动方式。 基本上 filter:input.filterUser 对尚未翻译的 $scope.groups 数组进行操作，因此您需要在 ng-repeat 之前翻译它> 发生。
