JS将嵌套对象转换为对象数组

function convertNestedObjectToArr(obj) {
  var arr = [];

  function recursive(obj) {
    for (var key in obj) {
      if (obj.hasOwnProperty(key)) {
        var value = obj[key];
        if (typeof value === 'object') {
          recursive(value);
        } else {
          arr.push({ key: key, value: value });
        }
      }
    }
  }

  recursive(obj);
  return arr;
}

// 示例用法
var nestedObj = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  }
};

var arr = convertNestedObjectToArr(nestedObj);
console.log(arr);
