从JSON对象中删除键值对 [英] Remove key-value pair from JSON object

问题描述

我在下面有这个JSON对象;

I have this JSON object below;

[
    {
        XXX: "2",
        YYY: "3",
        ZZZ: "4"
    },
    {
        XXX: "5",
        YYY: "6",
        ZZZ: "7"
    },
    {
        XXX: "1",
        YYY: "2",
        ZZZ: "3"
    }
]

我想从json中删除YYY键值对象使得新的json对象看起来像这样;

I want to remove the YYY key-value from the json object such that the new json object will look like this;

[
    {
        XXX: "2",       
        ZZZ: "4"
    },
    {
        XXX: "5",       
        ZZZ: "7"
    },
    {
        XXX: "1",       
        ZZZ: "3"
    }
]

我试过删除jsonObject ['YYY'] 但这不正确。怎么能在javascript中完成？谢谢。

I tried delete jsonObject['YYY'] but this is not correct. How can this be done in javascript? Thank you.

推荐答案

你所谓的'JSON对象'实际上是一个JSON对象数组。你必须迭代每个成员并单独删除每个成员：

What you call your 'JSON Object' is really a JSON Array of Objects. You have to iterate over each and delete each member individually:

for(var i = 0; i < jsonArr.length; i++) {
    delete jsonArry[i]['YYY'];
}
