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;});

其他回答

首先注入$filter到你的控制器中,确保ngSanitize被加载到你的应用中,随后在控制器中使用如下:

$filter('linky')(text, target, attributes)

经常查看angularjs的文档

还有另一种方法来计算从视图中镜像语法的过滤器。调用是复杂的,但您可以构建到它的快捷方式。我喜欢这个字符串的语法和视图中的是一样的。看起来是这样的:

function myCtrl($scope, $interpolate) { 
  $scope.$eval($interpolate( "{{ myvar * 10 | currency }} dollars." ))
}

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;});

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");
