如何在对象数组中找到一个对象的所有匹配的键和值？

function findMatchingKeysAndValues(objArray, targetKey) {
  var result = [];
  
  for (var i = 0; i < objArray.length; i++) {
    var obj = objArray[i];
    
    for (var key in obj) {
      if (key === targetKey) {
        result.push({ key: key, value: obj[key] });
      }
    }
  }
  
  return result;
}

var data = [
  { name: 'Alice', age: 25, city: 'New York' },
  { name: 'Bob', age: 30, city: 'San Francisco' },
  { name: 'Charlie', age: 35, city: 'New York' }
];

var result = findMatchingKeysAndValues(data, 'city');
console.log(result);

[
  { key: 'city', value: 'New York' },
  { key: 'city', value: 'San Francisco' },
  { key: 'city', value: 'New York' }
]
