在数组javascript中对相似的对象值进行分组

我有如下初始数据：

[
    {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"RCU","tot":1
    }
]

    [
        {
            "ru":"R401",
            "tot":[1, 1, 1, 1],
            "unit":["OFFSITE","OFFSITE","OFFSITE","RCU"]
        }
    ]

[
    {
        "ru":"R401",
        "tot":[1, 1],
        "unit":["OFFSITE","RCU"]
    }
]

如果某些键相同，我想在对象中推送数组，结果如下：

[
    {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"RCU","tot":1
    }
]

    [
        {
            "ru":"R401",
            "tot":[1, 1, 1, 1],
            "unit":["OFFSITE","OFFSITE","OFFSITE","RCU"]
        }
    ]

[
    {
        "ru":"R401",
        "tot":[1, 1],
        "unit":["OFFSITE","RCU"]
    }
]

然后，我想将对象“tot”和“unit”分组，然后将其放入一个新数组，如果键“tot”和“unit”的对应值相同，但我的逻辑不好

我希望输出是这样的：

[
    {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"OFFSITE","tot":1
    }, {
        "ru":"R401","area":"RFCC","unit":"RCU","tot":1
    }
]

    [
        {
            "ru":"R401",
            "tot":[1, 1, 1, 1],
            "unit":["OFFSITE","OFFSITE","OFFSITE","RCU"]
        }
    ]

[
    {
        "ru":"R401",
        "tot":[1, 1],
        "unit":["OFFSITE","RCU"]
    }
]

我该怎么做？ 提前感谢。

您可以使用a和两个数组的相应值，假设它们具有相同的长度

var object={ru:“R401”，tot:[1,1,1,1]，单位：[“场外”、“场外”、“场外”、“RCU”]，
唯一=新设置，
i=object.tot.length，
json；
而(我--){
json=json.stringify（[object.tot[i]，object.unit[i]]）；
if（unique.has（json））{
对象总拼接（i，1）；
对象.单位.拼接（i，1）；
持续
}
添加（json）；
}
console.log（对象）正确，使用Set是正确的选择

我会让它更通用：


const源=[
{
“ru”：“R401”，
“tot”：[1,1,1,1]，
“单位”：[“场外”、“场外”、“场外”、“RCU”]
}];
source.map（el=>{
Object.entries（el.forEach）（en=>{
if（Array.isArray（el[en[0]]））
el[en[0]]=Array.from（新集合（el[en[0]]）；
});
});
console.log（源代码）到目前为止您尝试过的任何东西？您可以尝试为单元设置<代码>设置
。为什么
[1，1]
而不是
[1]
？如果将它们分组，为什么在
tot
中有2个
1
？
