問(wèn)題描述
我有一個(gè)<Client>.on函數(shù)，我想停止監(jiān)聽這個(gè)事件，例如:
I have a <Client>.on function and I want to stop the listening of this event, example:
bot.on('messageCreate', message => {
// some code
});
如何停止它并且不再接收此事件?
How to stop it and not receive this event anymore?
推薦答案
我假設(shè) bot 是 Client，它擴(kuò)展了 Node.js 的 EventEmitter.您可以使用 message 或 ready)="nofollow noreferrer">on 并使用 關(guān)閉.addListener 和 removeListener 也分別是 on 和 off 的別名.
I'm assuming bot is an instance of Client, which extends Node.js' EventEmitter. You can listen to an event (for example message or ready) using on and remove that listener using off. addListener and removeListener are also aliases of on and off respectively.
將監(jiān)聽器函數(shù)存儲(chǔ)在一個(gè)變量中，當(dāng)你需要移除那個(gè)監(jiān)聽器時(shí)使用 bot.off(eventName, listener):
Store the listener function in a variable, and when you need to remove that listener use bot.off(eventName, listener):
const listener = () => {
// your code here...
}
bot.on('event', listener)
// When you need to remove the listener:
bot.off('event', listener)
