angularjs - Angularjs Controller 中的过滤器数组

Question

我有示例 Json。根据关键值，我更适合。

拟合器没有对精确值进行排序

示例:

angular.module('myApp').controller('testController', ['$filter', '$scope',
function($filter, $scope) {

    var obj = '[{"id":"1","m_id":1,"value":"Male"},
                {"id":"2","m_id":1,"value":"Female"},
                {"id":"3","m_id":1,"value":"Other"},
                {"id":"45","m_id":9,"value":"Single"},
                {"id":"46","m_id":9,"value":"Married"},
                {"id":"47","m_id":10,"value":"Father"},
                {"id":"48","m_id":10,"value":"Mother"},
                {"id":"61","m_id":10,"value":"Cousin"},
                {"id":"62","m_id":10,"value":"Other"}]';

    var obj1 = JSON.parse(obj);
    var result = $filter('filter')(obj1, {
        m_id : "1"
    });
}]);

输出:

[{"id":"1","m_id":1,"value":"Male"},
 {"id":"2","m_id":1,"value":"Female"},
 {"id":"3","m_id":1,"value":"Other"},
 {"id":"47","m_id":10,"value":"Father"},
 {"id":"48","m_id":10,"value":"Mother"},
 {"id":"61","m_id":10,"value":"Cousin"},
 {"id":"62","m_id":10,"value":"Other"}]

预期输出:

[{"id":"1","m_id":1,"value":"Male"},
 {"id":"2","m_id":1,"value":"Female"},
 {"id":"3","m_id":1,"value":"Other"}]

您也可以通过使用Javascript Filter()来做到这一点:

var result = obj1.filter(function(v){
    return v.m_id == 1;
});

在 AngularJS v.1.1.3 中，精确过滤器是 provided natively

var result = $filter('filter')(obj1, 
    {m_id : 1},
    true // ==========> this is for exact match
);
