Question

我正在创建一个不和谐的bot，我想创建一个命令来删除其名称（0、1、2、3、4、5、6、7、8、9等）的通道。我要删除的通道将具有单个名称，因此我使用了for循环。这是我的代码；我不知道为什么这行不通，请先谢谢你。

const Discord = require('discord.js');
const client = new Discord.Client();
module.exports = {
 name: 'delchannels',
 execute(message) {
  for (let i = 0; i < 10; i++) {
   let fetchedChannel = message.guild.channels.cache.find(i);
   fetchedChannel.delete();
  }
 },
};

哦，是的，我有这个错误：

Collection.find()需要一个功能参数。它将在数组的每个元素上运行给定的函数，并返回满足该函数的第一个元素。另外，i是一个数字，因此您也必须将频道名称转换为数字。

for (let i = 0; i < 10; i++) {
 let fetchedChannel = message.guild.channels.cache.find(
  (channel) => +channel.name === i
 );
 fetchedChannel.delete();
}

const channels = [
 {
  name: '0',
  id: 123,
 },
 {
  name: '1',
  id: 234,
 },
 {
  name: '2',
  id: 345,
 },
 {
  name: '3',
  id: 456,
 },
];
for (var i = 0; i < channels.length; i++) {
 console.log(channels.find((channel) => +channel.name === i).id);
}

仅作为提示，我相信您可以像这样缩短功能：

for (let i = 0; i < 10; i++) {
 let fetchedChannel = message.guild.channels.cache.find((c) => +c.name === i);
 fetchedChannel.delete();
}

// change to:
message.guild.channels.cache
 .filter((c) => /^[0-9]$/.test(c.name))
 .forEach((c) => c.delete());
