records:[{policyValue: "1,3" ,policyName:'hh',,dictList:[{dictKey:'1',dictValue;'zx'}, {dictKey:'2',dictValue;'zx'}]}, {policyValue:"1"policyName:'hh',,dictList:[{dictKey:'1',dictValue;'zx'},{dictKey:'2',dictValue;'zx'}}] 将records数组中policyName字段改为laber 将dictList数组中的dictValue字段改为laber，并将元素组返回

以下是 JavaScript 代码实现：

const updatedRecords = records.map(record => {
  const updatedDictList = record.dictList.map(dict => {
    return { dictKey: dict.dictKey, laber: dict.dictValue };
  });
  return { policyValue: record.policyValue, laber: record.policyName, dictList: updatedDictList };
});

console.log(updatedRecords);

输出结果为：

[
  {
    "policyValue": "1,3",
    "laber": "hh",
    "dictList": [
      { "dictKey": "1", "laber": "zx" },
      { "dictKey": "2", "laber": "zx" }
    ]
  },
  {
    "policyValue": "1",
    "laber": "hh",
    "dictList": [
      { "dictKey": "1", "laber": "zx" },
      { "dictKey": "2", "laber": "zx" }
    ]
  }
]
