Filter, JSON, indem Sie Schlüssel-Wert -

Habe ich folgenden JSON und ich will, dass das array in der gleichen Form, sondern nur Objekte mit Typ -"ar". Wie kann ich filter dieses JSON mit JavaScript nur die Typen, die ich brauche?

[{"time":"2016-07-26 09:02:27","type":"aa"},
{"time":"2016-04-21 20:35:07","type":"ae"},
{"time":"2016-08-20 03:31:57","type":"ar"},
{"time":"2017-01-19 22:58:06","type":"ae"},
{"time":"2016-08-28 10:19:27","type":"ae"},
{"time":"2016-12-06 10:36:22","type":"ar"},
{"time":"2016-07-09 12:14:03","type":"ar"},
{"time":"2016-10-25 05:05:37","type":"ae"},
{"time":"2016-06-05 07:57:18","type":"ae"},
{"time":"2016-10-08 22:03:03","type":"aa"},
{"time":"2016-08-13 21:27:37","type":"ae"},
{"time":"2016-04-09 07:36:16","type":"ar"},
{"time":"2016-12-30 17:20:08","type":"aa"},
{"time":"2016-03-11 17:31:46","type":"aa"},
{"time":"2016-05-04 14:08:25","type":"ar"},
{"time":"2016-11-29 05:21:02","type":"ar"},
{"time":"2016-03-08 05:46:01","type":"ar"},
]
Der wichtige technische Unterschied: JSON ist einer Zeichenkette (string) (es ist ein Weg, um die Serialisierung von JavaScript-Datenstruktur als string-Daten, nix mehr). Das einzige, was man machen kann, ist entweder string-Operationen durchführen, oder parse es in JavaScript-Datenstrukturen. Was Sie Fragen, ist die Filterung ein array von Objekten, basierend auf einige Schlüssel verwendet, um die Objekte; Sie sind nicht Fragen zum filtern von JSON.

    Nicht so sauber wie die Antwort oben, aber immer noch den job zu erledigen

    var list = [{"time":"2016-07-26 09:02:27","type":"aa"},
{"time":"2016-04-21 20:35:07","type":"ae"},
{"time":"2016-08-20 03:31:57","type":"ar"},
{"time":"2017-01-19 22:58:06","type":"ae"},
{"time":"2016-08-28 10:19:27","type":"ae"},
{"time":"2016-12-06 10:36:22","type":"ar"},
{"time":"2016-07-09 12:14:03","type":"ar"},
{"time":"2016-10-25 05:05:37","type":"ae"},
{"time":"2016-06-05 07:57:18","type":"ae"},
{"time":"2016-10-08 22:03:03","type":"aa"},
{"time":"2016-08-13 21:27:37","type":"ae"},
{"time":"2016-04-09 07:36:16","type":"ar"},
{"time":"2016-12-30 17:20:08","type":"aa"},
{"time":"2016-03-11 17:31:46","type":"aa"},
{"time":"2016-05-04 14:08:25","type":"ar"},
{"time":"2016-11-29 05:21:02","type":"ar"},
{"time":"2016-03-08 05:46:01","type":"ar"},
]

var newList = [];

for (var i = 0; i < list.length; i++) {
    if (list[i].type === 'ar') {
        newList.push(list[i]);
    }
}

console.log(newList);
