javascript - Discord.js 删除消息功能的问题

Question

我在使用 Discord.js 删除功能时遇到一些问题。当从 channel 中删除图像时，我使用此代码从用户的余额中删除 1 点，第一次一切正常，但是当我尝试删除我发送的另一张图像时，而不是从我的余额中删除 1 点，机器人将删除许多点，因为从机器人启动开始，总共删除了多少图像。示例:我删除一张图像，机器人将从我的余额中删除 1 点，然后如果我删除上传的另一张图像，它不会删除 1 点，而是从我的余额中删除 2 点，因为它会计算删除的第一张图像和这个。我该如何修复它并只响应删除的一张图像？

//(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扣除 1 点。

我的问题是我在 message 事件中发生了 messageDelete 事件。 attachIsImage() 应该在任何事件外部定义，然后在事件内部调用。
