如何在记录数组中按字段查找特定记录

// 假设记录数组是一个包含多个对象的数组，每个对象有id和name字段
const records = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Bob' },
];

function findRecordByField(records, field, value) {
  const foundRecords = [];

  for (let i = 0; i < records.length; i++) {
    if (records[i][field] === value) {
      foundRecords.push(records[i]);
    }
  }

  return foundRecords;
}

// 示例用法：按id字段查找id为2的记录
const foundRecords = findRecordByField(records, 'id', 2);
console.log(foundRecords); // 输出: [{ id: 2, name: 'Jane' }]
