javascript - 按键名过滤 JSON 数据

Question

我是 angularJS 的新手

我有这样的 JSON 数据:

[
{
    "REPORT_ID": "QDP56DSC4BK",
    "REPORT_NAME": "non, lobortis quis, pede.",
    "REPORT_STATUS": 1,
    "REPORT_TYPE": "Duis Sit Amet Ltd",
    "REPORT_DATE": "Sep 3, 2015",
    "REPORT_INGREDIENT_1": "Prednisone",
    "REPORT_INGREDIENT_2": "Alprazolam",
    "REPORT_INGREDIENT_3": "Prednisone",        

},
{
    "REPORT_ID": "JQY45UOQ8PY",
    "REPORT_NAME": "Cras dolor dolor, tempus",
    "REPORT_STATUS": 4,
    "REPORT_TYPE": "Sociis Incorporated",
    "REPORT_DATE": "Apr 26, 2015",
    "REPORT_INGREDIENT_1": "Clonazepam",
    "REPORT_INGREDIENT_2": "Hydrocodone/APAP",
    "REPORT_INGREDIENT_3": "Nuvaring",      
},
{
    "REPORT_ID": "EDE42OUH3FM",
    "REPORT_NAME": "posuere cubilia Curae; Donec",
    "REPORT_STATUS": 5,
    "REPORT_TYPE": "Pede Inc.",
    "REPORT_DATE": "May 22, 2015",
    "REPORT_INGREDIENT_1": "Furosemide",
    "REPORT_INGREDIENT_2": "Lipitor",
    "REPORT_INGREDIENT_3": "Losartan Potassium",

},
{
    "REPORT_ID": "BWQ55EIS6LS",
    "REPORT_NAME": "enim. Nunc ut erat.",
    "REPORT_STATUS": 1,
    "REPORT_TYPE": "Orci Sem Institute",
    "REPORT_DATE": "Dec 29, 2015",
    "REPORT_INGREDIENT_1": "Alprazolam",
    "REPORT_INGREDIENT_2": "Celebrex",
    "REPORT_INGREDIENT_3": "Promethazine HCl",
}
]

如何过滤此数据并将所有“REPORT_STATUS”数据存储在单独的数组中。

我的数组应该包含:[“REPORT_STATUS”:1，“REPORT_STATUS”:4，“REPORT_STATUS”:5，“REPORT_STATUS”:1]

让我们一起玩 builded functionality :

console.log(JSON.stringify(json, ['REPORT_STATUS']));

会产生

[{"REPORT_STATUS":1},{"REPORT_STATUS":4},{"REPORT_STATUS":5},{"REPORT_STATUS":1}]
