如果对象位于两个数组中，则仅选择选择中的选项

function getUniqueElements(A, B) {
  var result = [];

  for (var i = 0; i < A.length; i++) {
    if (B.includes(A[i])) {
      continue;
    } else {
      result.push(A[i]);
    }
  }

  for (var j = 0; j < B.length; j++) {
    if (A.includes(B[j])) {
      continue;
    } else {
      result.push(B[j]);
    }
  }

  return result;
}

// 示例用法
var arrayA = [1, 2, 3, 4, 5];
var arrayB = [3, 4, 5, 6, 7];
var uniqueElements = getUniqueElements(arrayA, arrayB);
console.log(uniqueElements); // 输出 [1, 2, 6, 7]
