数组和对象的处理！,

Question

const arr = [
  {
    
    "createdBy": "rmc-cmt-mbr-2",
    "topicSm": "456",
    "vot": "Yes"
  },
  {
    
    "createdBy": "rmc-cmt-mbr-2",
    "topicSm": "123",
    "vot": "Yes"
  },
  {
    
    "createdBy": "rmc-cmt-mbr-1",
    "topicSm": "123",
    "vot": "Yes"
  },
  {
    
    "createdBy": "rmc-cmt-mbr-1",
    "topicSm": "456",
    "vot": "No"
  },
  {
    "createdBy": "rmc-cmt-mbr-6",
    "topicSm": "123",
    "vot": "No"
  },
  {
   
    "createdBy": "rmc-cmt-mbr-6",
    "topicSm": "456",
    "vot": "No"
  }
]

const obj = {
    "topicSummaryList_0": {
        "topicSm_0": {
            "name": "topicSm_0",
            "value": "456"
        },
        "topic1_0": {
            "name": "topic1_0",
            "label": "Yes",
            "value": ""
        },
        "topic2_0": {
            "name": "topic2_0",
            "label": "No",
            "value": ""
        },
    },
    "topicSummaryList_1": {
        "topicSm_1": {
            "name": "topicSm_1",
            "value": "123"
        },
        "topic1_1": {
            "name": "topic1_1",
            "label": "Yes",
            "value": ""
        },
        "topic2_1": {
            "name": "topic2_1",
            "label": "No",
            "value": ""
        },
    }
}

不要使用for in 方法，根据数组的topicSm和obj.topicSummaryList.topicSm.value对比，并且数组的vot和obj.topicSummaryList.topic1.label对比，对比相同的结果，把数组的createdBy值给到obj.topicSummaryList.topic1.value或者obj.topicSummaryList.topic2.value，期望得到以下结果

const newObj = {
    "topicSummaryList_0": {
        "topicSm_0": {
            "name": "topicSm_0",
            "value": "456"
        },
        "topic1_0": {
            "name": "topic1_0",
            "label": "Yes",
            "value": "rmc-cmt-mbr-2，"
        },
        "topic2_0": {
            "name": "topic2_0",
            "label": "No",
            "value": "rmc-cmt-mbr-1，rmc-cmt-mbr-6"
        },
    },
    "topicSummaryList_1": {
        "topicSm_1": {
            "name": "topicSm_1",
            "value": "123"
        },
        "topic1_1": {
            "name": "topic1_1",
            "label": "Yes",
            "value": "rmc-cmt-mbr-2，rmc-cmt-mbr-1"
        },
        "topic2_1": {
            "name": "topic2_1",
            "label": "No",
            "value": "rmc-cmt-mbr-6"
        },
    }
}

Answer 1

    Object.keys(obj).forEach(k0 => {
        let keys = Object.keys(obj[k0]);
        var value = obj[k0][keys.filter(i => i.includes('topicSm_'))[0]].value;
        var items = arr.filter(i => i.topicSm == value);

        keys.filter(i => !i.includes('topicSm_')).forEach(i => {
            obj[k0][i].value = items.filter(x => x.vot == obj[k0][i].label).map(i => i.createdBy).join('，')
        })
    })
    console.log(obj)
