我正在处理这个项目，我需要从学校的时间表中获取所有空房间，我可以从 JSON 响应中获取数据。
JSON 响应如下所示：

回复要长得多，但为了简单起见，我将其缩短了。
所以我通过以下命令运行了这个 JSON 响应JSON.Parse() and for-loops获取数组中当前正在使用的所有房间；
var rooms = [];
for (var i = 0; i < json.reservations.length; i++) {
if(json.reservations[i].resources != null){
for(var j = 0; j < json.reservations[i].resources.length; j++){
var resource = json.reservations[i].resources[j];
if(resource.type === "room"){
if(rooms.indexOf("code"))
rooms.push(resource.code);
}
}
}
}
}
我得到了当时正在使用的所有房间，例如您可以从上面的回复中看到；
"startDate": "2017-04-24T08:00:00",
"endDate": "2017-04-24T09:45:00",
"type": "room",
"code": "A340.1",
但问题是，我正在使用的 API 目前不包含任何空房间的数据，所以我还为buildingA看起来像这样：
var buildingA = ['A120.3', 'A130.1', 'A130.3', 'A140.1', 'A140.2', 'A140.4', 'A250.1', 'A240.4', 'A240.2', 'A220.5', 'A220.3',
'A220.1', 'A210.2', 'A320.2', 'A320.6', 'A320.7', 'A320.8', 'A340.1', 'A340.2', 'A350.1', 'A350.3', 'A440.5', 'A450.3',
'A450.1', 'A440.4', 'A440.2', 'A420.6', 'A420.5', 'A420.4', 'A420.2', 'A510.2', 'A520.5', 'A510.4', 'A520.6', 'A520.7',
'A540.1', 'A540.2'];
有什么方法可以将这个数组与var rooms = [];数组以便我可以打印所有空房间而不是正在使用的房间？
至于结果，我必须查看空房间的名称以及空房间的时间（如果可能的话），但主要的是获取房间名称，例如；
A340.1 - 1 hour 45 minutes
A440.4 - 2 hours
提前致谢。
