JavaScript数组与JSON响应的比较
我有一个我正在做的项目，我需要从学校的时间表中获取所有的空房，我从JSON回复中获取数据 JSON响应如下所示：JavaScript数组与JSON响应的比较,javascript,arrays,json,api,compare,Javascript,Arrays,Json,Api,Compare,我有一个我正在做的项目，我需要从学校的时间表中获取所有的空房，我从JSON回复中获取数据 JSON响应如下所示： { "status": "success", "reservations": [ { "id": "19598", "subject": "subjectName", "modifiedDate": "2017-04-24T06:04:42", "startDate": "2017-04-

JSON.Parse（）for循环运行了这个JSON响应，以获取数组中当前使用的所有房间
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);
}
}
}
}
}
但问题是，我使用的API目前不包含任何空房间的数据，因此我还为buildingA
中的所有房间制作了一个数组，如下所示：

是否有任何方法可以将此数组与var rooms=[]进行比较数组，这样我就可以打印所有的空房间，而不是正在使用的房间
至于结果，我必须查看空置房间的名称以及空置的时间（如果可能的话），但最重要的是获取房间名称

"endDate": "2017-04-24T09:45:00",
"type": "room",

A340.1 - 1 hour 45 minutes
A440.4 - 2 hours
提前感谢。基本上，您可以先收集已预订的房间，然后获得完全免费的房间或提供免费时间

希望下面的内容有助于筛选数组
var vacantRooms = buildingA.filter((x) => {return !rooms.find((y) => {return y == x})});
结果应该是什么样的？你只想得到数组中的差异，就像这个答案一样？如果rooms
也以同样的方式拥有对象，那么一个快速的方法就是var diffArr=buildingA.filter（x=>！（新的集合（rooms））.has（x））
。这将产生一定的差异。但您可以循环并执行相同的操作。空闲时间需要所有可能的预订时间。谢谢！我现在有空房间代码。唯一剩下的就是为它们获取时间戳。
