在最多键匹配的两个对象数组中查找匹配项

function findMatchingItems(arr1, arr2) {
  var result = [];

  for (var i = 0; i < arr1.length; i++) {
    var obj1 = arr1[i];

    for (var j = 0; j < arr2.length; j++) {
      var obj2 = arr2[j];
      var isMatch = true;

      for (var key in obj1) {
        if (obj1.hasOwnProperty(key) && obj2.hasOwnProperty(key)) {
          if (obj1[key] !== obj2[key]) {
            isMatch = false;
            break;
          }
        } else {
          isMatch = false;
          break;
        }
      }

      if (isMatch) {
        result.push(obj2);
      }
    }
  }

  return result;
}

// 示例用法
var array1 = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Bob' }
];

var array2 = [
  { id: 1, name: 'John', age: 25 },
  { id: 2, name: 'Jane', age: 30 },
  { id: 4, name: 'Alice', age: 35 }
];

var matches = findMatchingItems(array1, array2);
console.log(matches);
