检查对象是否存在于数组中，不包括特定属性

function checkObjectInArray(arr, obj, excludedProps) {
  for (var i = 0; i < arr.length; i++) {
    var match = true;
    for (var prop in obj) {
      if (!excludedProps.includes(prop) && obj[prop] !== arr[i][prop]) {
        match = false;
        break;
      }
    }
    if (match) {
      return true;
    }
  }
  return false;
}

// 示例用法
var array = [
  { id: 1, name: 'John', age: 25 },
  { id: 2, name: 'Jane', age: 30 },
  { id: 3, name: 'Bob', age: 35 }
];

var object = { id: 2, name: 'Jane', age: 30 };

var excludedProperties = ['age'];

var exists = checkObjectInArray(array, object, excludedProperties);
console.log(exists); // 输出: true
