問題描述
我正在 discord.js 上編寫我自己的票務(wù)機(jī)器人.我需要檢查公會(huì)是否有頻道(按名稱).這是一小段代碼:
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;
}
我嘗試了以下方法:
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')
但沒有任何幫助
解決方案:正如 @Chiitoi 所建議的，在這種情況下最好使用 some() 函數(shù).另外，user.username返回的是帶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.
此代碼適用于我:
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;
}
推薦答案
我認(rèn)為 some() 方法 在這里可能很好.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.
