Question

如何根据ng-repeat中的其他数组过滤数组的结果。

我要过滤的数组：

[
    [
    'gender': 'male',
    'languages': ['German', 'English'],
    'country': 'Marocco'
    ],
    [
    'gender': 'female',
    'languages': ['German', 'French'],
    'country': 'Kosovo'
    ]
]

我想按此对象进行过滤：

   | filter:{'languages': ['Urdu', 'French'], 'country': ['Kosovo']}

预期结果：

[
'gender': 'female',
'languages': ['German', 'French'],
'country': 'Kosovo'
]

Answer 1

以下是基于您的代码的示例。我做了一些重要的改变：

您的数据数组是一个对象数组。
我将国家/地区更改为过滤器对象中的值。如果你还是希望它是一个数组，然后只需更改自定义中的代码过滤器就像语言一样工作。

    var app = angular.module('myApp',[]);

    app.controller('MyCtrl', ['$scope', function($scope) {
        $scope.data= [
            {
                'gender': 'male',
                'languages': ['German', 'English'],
                'country': 'Marocco'
            },
            {
                'gender': 'female',
                'languages': ['German', 'French'],
                'country': 'Kosovo'
            }
        ];
    }]);

    // Custom filter for our objects
    app.filter('myFilter', function () {
        return function (people, filterPerson) {
            var filtered = [];

            // Check if any elements in checkArray are in sourceArray
            var includesAny= function(checkArray,sourceArray){
                checkArray.forEach(function(element) {
                    if (sourceArray.includes(element)){return true;}
                });
                return false;
            };

            for (var i = 0; i < people.length; i++) {
                var person = people[i];
                if (filterPerson.country && filterPerson.country != person.country) {
                    continue;
                }

                if (filterPerson.gender && filterPerson.gender != person.gender) {
                    continue;
                }

                if (filterPerson.languages && includesAny(filterPerson.languages,person.languages)) {
                    continue;
                }

                filtered.push(person);
            }
            return filtered;
        };
    });
