如何在控制器中使用过滤器?

我已经写了一个过滤器函数，它将根据您传递的参数返回数据。我希望在控制器中有相同的功能。是否有可能在控制器中重用过滤器函数?

这是我目前为止尝试过的:

function myCtrl($scope,filter1)
{ 
    // i simply used the filter function name, it is not working.
}

当前回答

似乎没有人提到你可以在$filter('filtername')(arg1,arg2)中使用函数arg2;

例如:

$scope.filteredItems = $filter('filter')(items, function(item){return item.Price>50;});

使用下面的示例代码，我们可以通过名称过滤angular控制器中的数组。这是基于下面的描述。 http://docs.angularjs.org/guide/filter

这一点。filteredArray = filterFilter数组,{名称:“伊戈尔”});

JS:

 angular.module('FilterInControllerModule', []).
    controller('FilterController', ['filterFilter', function(filterFilter) {
      this.array = [
        {name: 'Tobias'},
        {name: 'Jeff'},
        {name: 'Brian'},
        {name: 'Igor'},
        {name: 'James'},
        {name: 'Brad'}
      ];
      this.filteredArray = filterFilter(this.array, {name:'Igor'});
    }]);

      All entries:
      <span ng-repeat="entry in ctrl.array">{{entry.name}} </span>
    </div>
    <div>
      Filter By Name in angular controller
      <span ng-repeat="entry in ctrl.filteredArray">{{entry.name}} </span>
    </div>
  </div>
</body>
</html>

如果你想在控制器中过滤对象，试试这个

var rateSelected = $filter('filter')($scope.GradeList, function (obj) {
                        if(obj.GradeId == $scope.contractor_emp.save_modal_data.GradeId)
                        return obj;
                });

这将根据if条件返回过滤后的对象

下面是在Angular控制器中使用过滤器的另一个例子:

$scope.ListOfPeople = [
    { PersonID: 10, FirstName: "John", LastName: "Smith", Sex: "Male" },
    { PersonID: 11, FirstName: "James", LastName: "Last", Sex: "Male" },
    { PersonID: 12, FirstName: "Mary", LastName: "Heart", Sex: "Female" },
    { PersonID: 13, FirstName: "Sandra", LastName: "Goldsmith", Sex: "Female" },
    { PersonID: 14, FirstName: "Shaun", LastName: "Sheep", Sex: "Male" },
    { PersonID: 15, FirstName: "Nicola", LastName: "Smith", Sex: "Male" }
];

$scope.ListOfWomen = $scope.ListOfPeople.filter(function (person) {
    return (person.Sex == "Female");
});

//  This will display "There are 2 women in our list."
prompt("", "There are " + $scope.ListOfWomen.length + " women in our list.");

很简单吧?

在控制器中使用$filter的简单日期示例如下:

var myDate = new Date();
$scope.dateAsString = $filter('date')(myDate, "yyyy-MM-dd");
