javascript - Angular Js在 Controller 中过滤嵌套数组

Question

我想在 Controller 中使用 angularjs 过滤器过滤嵌套数组。以下是我的样本数据

dummy=[
    {
        category:'TV',
        data:[
            {
                title: 'Game of Thrones',
                path: 'some data1',
            },
            {
                title: 'Game of Thrones-SD',
                path: 'some data2'
            },
            {
                title: 'Game of Thrones-HD',
                path: 'some data3'
            },
            {
                title: 'Game of Thrones-Trailer 1',
                path: "some data4"
            },
            {
                title: 'Game of Thrones-Trailer 2',
                path: "some data5"
            },
            {
                title: 'Game of Thrones-Trailer 3',
                path: "Ssome data6"
            },
            {
                title: 'The Vampire Diaries ',
                path: 'some data7'
            },
            {
                title: 'The Vampire Diaries -SD',
                path: 'some data8'
            },
            {
                title: 'The Vampire Diaries -HD',
                path: 'some data9'
            },
            {
                title: 'The Vampire Diaries -Trailer 1',
                path: 'some data10'
            }
        ]
    },
    {
        category:'LIVE',
        data:[
            {
                title: 'Game of Thrones - Live Show',
                path: 'some data11'
            },
            {
                title: 'The Vampire Diaries  - Live Show',
                path: 'some data11'
            }
        ]
    }
];

例如我想过滤标题上的数据，所以如果我搜索“权力的游戏”我想得到以下数据

    {
        category:'TV',
        data:[
            {
                title: 'Game of Thrones',
                path: 'some data1',
            },
            {
                title: 'Game of Thrones-SD',
                path: 'some data2'
            },
            {
                title: 'Game of Thrones-HD',
                path: 'some data3'
            },
            {
                title: 'Game of Thrones-Trailer 1',
                path: "some data4"
            },
            {
                title: 'Game of Thrones-Trailer 2',
                path: "some data5"
            },
            {
                title: 'Game of Thrones-Trailer 3',
                path: "Ssome data6"
            },
        ]
    },
    {
        category:'LIVE',
        data:[
            {
                title: 'Game of Thrones - Live Show',
                path: 'some data11'
            }
        ]
    }

我想这里也有人问过类似的问题 Angularjs filter nested object

我尝试在我的 Controller 中使用以下代码，但没有成功

var filterdData = $filter('filter')(content, {data: [{title: $scope.filterKey}]});

Answer 1

这对我有用

var filterdData = $filter('filter')(content, {data: {title: $scope.filterKey}});
