角度選擇請記住，當通過視圖移動

Question

我希望當我移動視圖並返回時，我選擇的選擇保持選定狀態。

這裏是視圖：

<select ng-model="getseason" class="form-control" ng-options="season as 'Season '+ season + '/' + seasonaddone(season) for season in seasons"> 

這裏是控制器：

$scope.seasons = [2014,2013,2012,2011,2010,2009,2008,2007,2006,2005]; 

$scope.getseason = $scope.seasons[0]; 

$scope.$watch('getseason',function(){ 

    var url = 'http://api.football-data.org/alpha/soccerseasons/?season=' + $scope.getseason; 

    apiDataService.GetData(url).then(function(data) { 

     $scope.leagues = data; 

    }); 

}); 

我知道，當我去從另一種觀點回來，再此控制器負載和設定值來season[0]。

創建一個服務並將此值存儲在那裏。 每個服務僅在每個應用程序負載中安裝一次，因此如果您在此處存儲值，則在路由更改後它不會消失。順便說一句。這也是一個存放模型的好地方（即季節數組）。示例實施：

app.controller('MyController', function ($scope, seasonHelper) { 

    $scope.getseason = seasonHelper.getseason; 
    $scope.$watch('getseason', function(){ 
     seasonHelper.getseason = $scope.getseason; 
     ... 
    }); 

}) 
.service('seasonHelper', function() { 

    this.seasons = [2014,2013,2012,2011,2010,2009,2008,2007,2006,2005]; 
    this.getseason = this.seasons[0]; 

});
