discord.js v12 检查频道是否存在
我正在 discord.js 上编写我自己的票务机器人.我需要检查公会是否有频道(按名称).这是一小段代码:
I'm coding my own ticket bot on discord.js. I need to check if guild have a channel (by name). Here's little piece of code:
if (userTickets.has(user.id) || reaction.message.guild.channels.cache.???(c => c.name === user.username.toLowerCase() + 's-ticket')) {
user.send("You already have a ticket!");
return;
}
我尝试了以下方法:
reaction.message.guild.channels.cache.find(c => c.name === user.username.toLowerCase() + 's-ticket')
reaction.message.guild.channels.cache.has(c => c.name === user.username.toLowerCase() + 's-ticket')
reaction.message.guild.channels.cache.has(user.username.toLowerCase() + 's-ticket')
但没有任何帮助
解决方案:正如 @Chiitoi 所建议的，在这种情况下最好使用 some() 函数.另外，user.username返回的是带有空格和特殊字符的字符串，所以需要解析一下.
SOLUTION:
As suggested by @Chiitoi, in this case it is better to use some() function.
Also, user.username returns string with spaces and special characters, so you need to parse it.
此代码适用于我:
if (userTickets.has(user.id) || reaction.message.guild.channels.cache.some((channel) => channel.name === username.replace(/[^a-zA-Z0-9-]/ig, "") + 's-ticket')) {
user.send("You already have a ticket!");
return;
}
推荐答案
我认为 some() 方法 在这里可能很好.user.username 返回什么?我想知道返回的值是否有任何特殊或唯一字符.
I think the some() method might be good here. And what does user.username return? I'm wondering if the returned value has any special or unique characters.
