比较2个JSON数组以获得匹配和不匹配的输出

function compareJSONArrays(jsonArray1, jsonArray2) {
  var matches = [];
  var mismatches = [];

  jsonArray1.forEach(function(element1) {
    var index = jsonArray2.findIndex(function(element2) {
      return JSON.stringify(element1) === JSON.stringify(element2);
    });

    if (index !== -1) {
      matches.push(jsonArray2[index]);
      jsonArray2.splice(index, 1);
    } else {
      mismatches.push(element1);
    }
  });

  mismatches = mismatches.concat(jsonArray2);

  return {
    matches: matches,
    mismatches: mismatches
  };
}

// 示例用法
var jsonArray1 = [
  { "id": 1, "name": "John" },
  { "id": 2, "name": "Jane" },
  { "id": 3, "name": "Bob" }
];

var jsonArray2 = [
  { "id": 2, "name": "Jane" },
  { "id": 3, "name": "Bob" },
  { "id": 4, "name": "Alice" }
];

var result = compareJSONArrays(jsonArray1, jsonArray2);

console.log("匹配的元素：", result.matches);
console.log("不匹配的元素：", result.mismatches);

匹配的元素： [ { id: 2, name: 'Jane' }, { id: 3, name: 'Bob' } ]
不匹配的元素： [ { id: 1, name: 'John' }, { id: 4, name: 'Alice' } ]
