不和谐的问题。js删除消息功能

Question

我有一些不和谐的问题。js删除函数。我使用这段代码在从频道中删除图像时从用户的余额中删除1点，这是第一次一切正常，但当我尝试删除我发送的另一个图像时，机器人将从我的余额中删除1点，而不是从我的余额中删除1点，因为从机器人启动开始，总共删除了多少图像。示例：我删除一个图像，机器人将从我的余额中删除1个点，然后如果我删除我上传的另一个图像，而不是删除1个点，它将从我的余额中删除2个点，因为它将计算删除的第一个图像和该点。如何修复它并仅对删除的一个图像作出响应？

js prettyprint-override">//(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;
});

机器人应该只从用户的余额中删除1点。

我的问题是，我有MessageDelete事件在消息事件内。attachIsImage（）应该在任何事件之外定义，然后在它们内部调用。
