Question

当我使用以下数字过滤对象数组时：

$scope.users = [{name:'John', id:-1},
                         {name:'Mary', id:1},
                         {name:'Mike', id:2},
                         {name:'Adam', id:3}];

var selected = $filter('filter')($scope.users, {id: $scope.target});

如果target = 1，则所选结果将包括John和Mary。但我只想要包含与id为1的Mary完全相同的id。为什么包含负数？我该如何防止这种情况？

您可以将比较器的第三个参数设置为真

$scope.users = [{name:'John', id:-1},
                         {name:'Mary', id:1},
                         {name:'Mike', id:2},
                         {name:'Adam', id:3}];

var selected = $filter('filter')($scope.users, {id: $scope.target}, true);

true是：

的简写

function(actual, expected) { 
    return angular.equals(actual, expected)
} // This is essentially strict comparison of expected and actual.

AngularJS过滤器包含负数
