Question

我是discord.js的新手，我想知道如何解决此错误。您能否修复我的代码，然后告诉我将来如何避免此问题？谢谢！

代码：

client.on('message', message => {
if (message.content === '-ping') {
    const embed = {
        "title": "**Ping Results**",
        "fields": [
          {
            "name": "Bot",
            "value": "" +(botMsg.createdAt - message.createdAt) + "ms"
          },
          {
            "name": "API ",
            "value": Math.round(client.ping) + "ms"
          },
          {
            "name": "Uptime",
            "value": msToTime(client.uptime) + "ms"
          }
        ]
      };
      message.channel.send({ embed });
}

}）;

控制台错误：

此错误表示未定义变量botMsg。

如我所见，您想执行ping命令，并且botMsg是您要收集的已发送消息。

此代码应该有效。

client.on('message', message => {
  if (message.content === '-ping') {
    message.channel.send("Checking the ping...").then(botMsg => {
        const embed = {
            "title": "**Ping Results**",
            "fields": [
              {
                "name": "Bot",
                "value": "" +(botMsg.createdAt - message.createdAt) + "ms"
              },
              {
                "name": "API ",
                "value": Math.round(client.ping) + "ms"
              },
              {
                "name": "Uptime",
                "value": msToTime(client.uptime) + "ms"
              }
            ]
          };
          botMsg.edit({ embed });
    })
  }
});
