【问题描述】：

我有 2 个对象 a 和 diff 我需要嵌套对象“a”中的匹配数组或对象。

输入如下：

 var a = {
"AMI_DESCRIPTION":{
    "tags":{
        "aws":1,
        "vendor_param":1
    }
},
"AMI_ID":{
    "description":"The AWS AMI id for the version of Ontap for the VSA to boot up with",
    "tags":{
        "aws":1,
        "vendor_param":1
    }
},
"AMI_TYPE":{
    "allow":[
        "byol",
        "paygo10",
        "paygo2",
        "paygo"
    ],
    "default":"byol",
    "description":"Defined the type of Cloud Ontap AMI to be deployed",
    "tags":{
        "aws":1,
        "vendor_param":1
    }
},
"AWSCLI_PATH":{
    "default":"/usr/software/bin/aws",
    "description":"Path to AWS CLI binaries",
    "tags":{
        "aws":1,
        "dev_only":1,
        "vendor_param":1
    }
},
"AWS_DISABLE_ROLLBACK":{
    "allow":[
        "true",
        "false"
    ],
    "default":"false",
    "description":"",
    "tags":{
        "aws":1,
        "dev_only":1,
        "unsupported":1,
        "vendor_param":1
    }
},
"IMAGE_BUILDNAME":{
        "allow":[
            "cst-ok",
            "cit-ok",
            "none",
            "ignore_filter"
        ],
        "default":"cit-ok",
        "description":"filter",
        "tags":{
            "aws":1,
            "gcp":1,
            "vendor_param":1
        }
},
"IMAGE_DEBUG_TYPE":{
        "description":"tedst",
        "tags":{
            "common":1,
            "vendor_param":1
        }
},

映射a 对象并返回diff 对象中存在的字段的值

 var diff = {
    "IMAGE_BUILDNAME":"testing",
    "IMAGE_DEBUG_TYPE":"no"

}

预期输出：

  "IMAGE_BUILDNAME":{ "description":"sdsd.", "tags":{ "aws":1, "gcp":1, 
  "vendor_param":1 } }, "IMAGE_DEBUG_TYPE":{ "allow":[ "debug", "non-debug", 
  "ignore_filter" ], "default":"non-debug", "description":"filter.", "tags":{                
   "aws":1, "gcp":1, "vendor_param":1 } }

提前致谢

【问题讨论】：

请提供更多详情
我已经编辑了输出，因此您可以阅读它 - 请提供从输入到输出的逻辑
然后你去撤消这一切 - 干得好
@JaromandaX 抱歉撤消了它。我没有检查过
例如，为什么是"description": "sdsd." - 这是从哪里来的？输出中的"allow": ["debug", "non-debug", "ignore_filter"] 怎么样？为什么debug 在该数组中？同样对于输出中的其他属性，没有逻辑

【解决方案1】：

循环遍历diff 属性并将diff 的每个属性添加到output 作为字段及其来自a 对象的值：

 var output = {};

    for (let p in diff) {
        output[p]=a[p]
    }

    var output = {};
