[英]How to get the count field in messageReaction collection discord.js
[英]Discord.js collection; how to navigate and grab/count objects from an array in a collection
我有一个 discord.js Collection
,如下所示:
Collection(1) [Map] {
'403547647215927306' => {
dispatcher: StreamDispatcher {
_writableState: [WritableState],
writable: true,
_events: [Object: null prototype],
_eventsCount: 5,
_maxListeners: undefined,
player: [AudioPlayer],
streamOptions: [Object],
streams: [Object],
_nonce: 2369,
_nonceBuffer: <Buffer 00 00 09 41 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00>,
pausedSince: null,
_writeCallback: [Function (anonymous)],
broadcast: undefined,
_pausedTime: 0,
_silentPausedTime: 0,
count: 2369,
startTime: 1588923698004,
[Symbol(kCapture)]: false
},
queue: [ [Object], [Object], [Object] ],
connection: null,
position: 0
}
}
我想分离并计算调度程序的数量和队列中的对象数量。 我已经能够使用 #dispatcher(s)
var playlistCount = client.playlists.filter(q => q.dispatcher).size // returns 1 for code, 2 for image
但是使用类似的方法
var playlistList = client.playlists.filter(q => q.queue).size // returns 1 for code, 2 for image
这应该是队列中的3
首歌曲,而不是1
(或图像中的2
)队列处于活动状态。 有人可以建议如何过滤队列对象以返回大小/长度/计数吗?
您可以使用find()
查找queue
并获取其length
var playlistList = client.playlists.find(playlist => playlist.queue).length
