在Angular中，我有这两个包含对象的数组。

  1. 主要对象
[
    {
        "userId": 8,
        "name": "Adfgh",
        "uniqueId": "rthj",
        "source": {
            "key": "0",
            "mode": "d",
            "name": "tev5"
        },
        "headers": [
            {
                "content": "b",
                "id": "01"
            },
            {
                "content": "m",

  1. 第二个对象
[
    {
        "Id": 098,
        "UniqueId": "remove",
        "Destination": "",
        "Key": "",

        "Destination": "",
        "Key": "",
        "Name": "A-KEYTST-PNP-NHMAC",
        "Enable": false,
        "Auto": 0
    },
]

期望结果。

    },

        ],
        "keyType": "IPP Master Key",
        "destination": "7"
    },
]

要比较它们，我创建了一个分离的数组，以使它们相似。我尝试使用过滤器和映射，但没有帮助。

我尝试了不同的方法，但没有成功。所以我没有代码片段。需要根据它们之间的差异比较主要对象和第二个对象，然后修改主要对象。

英文:

In Angular I have this 2 arrays with objects.

  1. Main Object

  2. second object

    [

    "Key": "",
    "Name": "A-KEYTST-PNP-NHMAC",
    "Enable": false,
    "Auto": 0

expected result.

            {
                "content": "7",
                "id": "05"
            }
        ],
        "keyType": "IPP Master Key",
        "destination": "7"
    },
]

For to compare them, I created a seperated array for to make them similiar to each other. Used filter, map but it wasn't helpful.

I have tried in different ways, and nothing worked. So I don't have the snippet for the code.
Need to compare main object and second object, based on the difference between them have to modify main object.

Sure, here's the translated code:

function updateMainObject(mainArray: any[], secondArray: any[]) {
    const updatedMainArray = mainArray.filter((mainItem) => {
        return (
            mainItem &&
            ((mainItem.uniqueId && !secondArray.some((secondItem) => mainItem.uniqueId === secondItem.UniqueId)) ||
                (mainItem.userId && !secondArray.some((secondItem) => mainItem.userId === secondItem.Id)))
        );
    });

    return updatedMainArray;
}

You can play with it here.

英文:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

function updateMainObject(mainArray: any[], secondArray: any[]) {
    const updatedMainArray = mainArray.filter((mainItem) =&gt; {
    return (
      mainItem &amp;&amp;
      ((mainItem.uniqueId &amp;&amp; !secondArray.some((secondItem) =&gt; mainItem.uniqueId === secondItem.UniqueId)) ||
      (mainItem.userId &amp;&amp; !secondArray.some((secondItem) =&gt; mainItem.userId === secondItem.Id)))
    );
  });

  return updatedMainArray;
}

<!-- end snippet -->

You can play with it there
