从javascript对象数组中删除一些属性 [英] Remove some properties from array of javascript objects

问题描述

我想从javascript对象数组中删除一些属性.这是对象的数组.

I would like to remove some properties from an array of javascript objects. Here is the array of objects.

obj_array = [{
        "DATA_ID": 1,
        "DATA_NAME": "Jim",
        "DATA_BB_TYP": 2,
        "DATA_MAC": "5474",
    },
    {
        "DATA_ID": 3,
        "DATA_NAME": "Fro",
        "DATA_BB_TYP": 33,
        "DATA_MAC": "8e30",
    },
    {
        "DATA_ID": 2,
        "DATA_NAME": "Jimb",
        "DATA_BB_TYP": 2,
        "DATA_MAC": "45e8",
    },
    {
        "DATA_ID": 4,
        "DATA_NAME": "Kht1",
        "DATA_BB_TYP": 35,
        "DATA_MAC": "58d0",
    },
    {
        "DATA_ID": 6,
        "DATA_NAME": "Sens",
        "DATA_BB_TYP": 34,
        "DATA_MAC": "d004",
    }
]

我有这个字符串数组，用于指定要删除的属性.

I have this string array which specifies what properties to remove.

var str_array_criteria = ["DATA_BB_TYP", "DATA_MAC"];

删除后，对象数组将如下所示；

After removal, the array of object will look like this;

obj_array_removed = [{
        "DATA_ID": 1,
        "DATA_NAME": "Jim",        
    },
    {
        "DATA_ID": 3,
        "DATA_NAME": "Fro",
    },
    {
        "DATA_ID": 2,
        "DATA_NAME": "Jimb",
    },
    {
        "DATA_ID": 4,
        "DATA_NAME": "Kht1",
    },
    {
        "DATA_ID": 6,
        "DATA_NAME": "Sens",
    }
]

我正在使用node.js v6.

推荐答案

您可以使用下划线实现此目的.它更加简单易读

You can use underscore to achieve this. It's much simpler and more readable

obj_array.map(obj => _.omit(obj,["DATA_BB_TYP", "DATA_MAC"]))
