Question

discord.js删除功能遇到一些问题。从频道删除图片时，我第一次使用此代码从用户的余额中删除1点，但一切正常，但是当我尝试删除发送的另一张图片时，而不是从余额中删除1点，该机器人将删除许多点，因为从该机器人启动以来，总共删除了多少张图片。示例：我删除了一张图片，机器人会从我的余额中删除1点，然后，如果我删除了我上传的另一张图片，而不是删除1点，它将从我的余额中删除2点，因为它将计算删除的第一张图片还有这个。我该如何解决它并仅对删除的一张图像做出反应？

//(works) This is the function that make the bot read the message's attach
function attachIsImageJPG(messageAttach) {
  var url = messageAttach.url;
  //True if this url is a png image.
  return url.indexOf("jpg", url.length - "jpg".length /*or 3*/) !== -1;
}

//(works) There's the code that make the bot assign 1 point when the image is uploaded
  if (message.attachments.size > 0) {
    if (message.channel.id != '593093789971644417') return;
      if (message.attachments.every(attachIsImage)){
        eco.AddToBalance(message.author.id, 1)
        bot.channels.get("593093471175311438").send(itag + message.author.id + ftag + " **1** has been **added** to your `!balance` for sending the success the screenshot");
    }
}

//(problem) This is the part with the error
bot.on("messageDelete", async (messageDelete) => {
  if (messageDelete.channel.id === '593093789971644417') {

    function attachIsImageJPG(messageAttach) {
      var url = messageAttach.url;
      //True if this url is a png image.
      return url.indexOf("jpg", url.length - "jpg".length /*or 3*/) !== -1;
  }
  if (message.attachments.size > 0) {
    if (message.attachments.every(attachIsImageJPG)) {
      await eco.SubstractFromBalance(message.author.id, 1) // money.updateBal grabs the (userID, value) value being how much you want to add, and puts it into 'i'.
      return bot.channels.get("593093471175311438").send(itag + message.author.id + ftag + " **1** has been **removed** from your `!balance` for deleting the screenshot");
} else return;
  } else return;
  } else return;
});

机器人应从用户的余额中删除1点。

我的问题是我在messageDelete事件中有一个message事件。 attachIsImage()应该在任何事件之外定义，然后在事件内部调用。
