Question

我正在尝试过滤掉json数据。这就是我所做的。

angular.module('staticSelect', [])
  .controller('ExampleController', ['$scope', function($scope) {
    $scope.data = {
      multipleSelect: ["classA"]
    };
    $scope.isoffice = function(apps) {

      return apps.type === $scope.data.multipleSelect[0];
    };
    console.log($scope.data.multipleSelect[0]);
            $scope.apps = [{
      "id": "1",
      "type": "classA",
      "name": "Name 1"
    }, {
      "id": "2",
      "type": "classB",
      "name": "Name 2"
    }, {
      "id": "3",
      "type": "classC",
      "name": "Name 3"
    }, {
      "id": "4",
      "type": "classD",
      "name": "Name 4"
    }, {
      "id": "5",
      "type": "classE",
      "name": "Name 5"
    }
    ];
  }]);

当用户只从列表中选择一个值并且＆＃34;键入＆＃34;不是数组。但是，我想知道如何过滤下面的数据，用户可以从列表中选择多个值，并通过考虑OR条件来过滤数据。

$scope.apps = [{
      "id": "1",
      "type": ["classA","classB","classC"],
      "name": "Name 1"
    }, {
      "id": "2",
      "type": ["classB","classC","classE"],
      "name": "Name 2"
    }, {
      "id": "3",
      "type": ["classC"],
      "name": "Name 3"
    }, {
      "id": "4",
      "type": ["classD","classC"],
      "name": "Name 4"
    }, {
      "id": "5",
      "type": ["classA","classB","classC","classD","classE"],
      "name": "Name 5"
    }
    ];

EX。如果用户选择A类和B类，那么输出将是名称1，名称2，名称5
