【问题描述】：

我试图让用户能够从我的数组中选择项目，并将该 gif / 图像打印在发送它的通道中。 机器人还将检查用户发送的任何参数是否在数组中，如果是，机器人将继续发送图像/gif。如果不是，机器人将发送不正确的使用嵌入。

module.exports = 
  name: "anime",
  description: "Generates random anime gif",
  async execute(message, args) 
    let animearray = [
      "angry",
      "anime",
      "bite",
      "bored",
      "bread",
      "chocolate",
      "cookie",
      "cuddle",
      "dance",
      "drunk",
      "happy",
      "kill",
      "kiss",
      "laugh",
      "lick",
      "lonely",
      "pat",
      "poke",
      "pregnant",
      "punch",
      "run",
      "satouselfies",
      "sleep",
      "spank",
      "steal",
      "tickle",
    ];
    // incorrect usage 
    const inc = new Discord.MessageEmbed()
    .setDescription(`The category you selected is currently not avaiable. Please take a look at the current list by using: $config.PREFIXlist`)
    .setColor('#E74C3C')

    //selecting a category from array 
    const announcement = args.slice(1).join(" ")
      if(!announcement) return message.reply(inc)

    // whatever was selected in const variable would be  the data
    const outc = new Discord.MessageEmbed()
    .setDescription(data)
    .setColor('#E74C3C')
    
   



    await message.channel.send(outc);
  ,
;

示例

用户：

Bot：打印愤怒的图像/gif（因为它在数组中）

【问题讨论】：

您将需要一种将输入映射到表情符号名称的方法。我会使用一个对象，这样您就可以从用户输入中索引，并将表情符号名称作为键/值对的值。然后，您不必循环数组来查找您需要添加的 key=user_summited_value。

【参考方案1】：

希望你今天过得愉快！

这是你的代码

module.exports = 
  name: "anime",
  description: "Generates random anime gif",
  async execute(message, args) 
    let animearray = [
      "angry",
      "anime",
      "bite",
      "bored",
      "bread",
      "chocolate",
      "cookie",
      "cuddle",
      "dance",
      "drunk",
      "happy",
      "kill",
      "kiss",
      "laugh",
      "lick",
      "lonely",
      "pat",
      "poke",
      "pregnant",
      "punch",
      "run",
      "satouselfies",
      "sleep",
      "spank",
      "steal",
      "tickle",
    ];
    // incorrect usage 
    const inc = new Discord.MessageEmbed()
    .setDescription(`The category you selected is currently not avaiable. Please take a look at the current list by using: $config.PREFIXlist`)
    .setColor('#E74C3C')

    //selecting a category from array 
    const announcement = args.slice(1).join(" ")
      if(!announcement) return message.reply(inc)

    // whatever was selected in const variable would be  the data
    const outc = new Discord.MessageEmbed()
    .setDescription(data)
    .setColor('#E74C3C')
    
    await message.channel.send(outc);
  ,
;

所以您只需要检查args.slice(1).join(" ") 是否存在于数组中，所以只需：

if(!animearray.includes(args.slice(1).join(" ").toLowerCase())) return message.channel.send(inc)

否则只需检查参数并根据它发送图像/gif。

例子：

if(args.slice(1).join(" ").toLowerCase() == 'dance') return message.channel.send(/* image/gif */)
