                "referenceObjectId": null
            }
        ]
    }
]
}

在JS以下尝试

 data.attributeValues.forEach((item, i) => {
const itemattrId = item.attributeList[i].attributeId;            
data.attributeMetaData.forEach((subItem, j) => {
  const subitemattrId = subItem.attributeId;
  if (itemattrId === subitemattrId) {
    console.log(subItem.attributeName + ' - ' + item.attributeList[i].attributeValue);
  }             
});
});

我想遍历此JSON以获取列名和列值的映射。在JSON中，映射是通过名为“ attributeId”的属性完成的。在“ attributeMetaData”中，“ attributeName”是列的名称，在“ attributeValues”中，存在多个“ attributeList”，并且每个属性都有“ attributeId”和“ attributeValue”属性。实际上，我正在尝试将对象构建为适当的名称值对，以将其绑定到网格。因此，基于“ attributeId”，我想映射每个名称值对。任何帮助将不胜感激。谢谢。

const idToNameMap = {};
obj.attributeMetaData.forEach(item => {
   idToNameMap[item.attributeId] = item;                               
})

const rows = obj.attributeValues.map(attributeObj => {
   const row = { objectId: attributeObj.objectId };
   attributeObj.attributeList.forEach(attr => { 
      if (idToNameMap[attr.attributeId].isHidden !== "true") {
         row[idToNameMap[attr.attributeId].attributeName] = attr.attributeValue;
      }
   });
   return row;
});

console.log(rows); //Prints:
//[
//  {
//    objectId: 133218,
//    OWNERTYPE: 'Entity',
//    OWNERSTATUS: 'Active',
//    PREFERREDNAME: null,
//  },
//  {
//    objectId: 134179,
//    OWNERTYPE: 'Individual',
//    OWNERSTATUS: 'Active',
//    PREFERREDNAME: 'Ra vi Teja',
//  }
//]
