Node.js message.split 返回未定义

Question

所以我想创建一个机器人命令，当我输入时-say Something Here 它返回 someone said: Something here 但它所做的只是返回 someone said: undefined 顺便说一句，我正在使用 tmi.js

bot.on("chat", function (channel, user, message, self) {
  if(message === "-say")
    var code = message.split('  ')[1];
    bot.action("stankotomic", "someone says: " + code);
});

我不太确定，但我认为你的意思是别的。告诉我我是否理解错了。但据我理解你的问题，这是正确的方法。

考虑到该消息 =“-say Something Here”；你的结果应该是:“有人说:这里有东西”

让我们逐行查看您的代码:

if(message === "-say") // I am 100% sure "-say" and 
//"-say something here" are different. correct me if i am wrong.
//so we need to check for the first word, or first element in our array of words. 
//lets first create array than check: if(message.split(" ")[0] == "-say")

var code = message.split('  ')[1]; //now, we don't have 2 spaces together 
//anywhere in our message, so array == nothing. 
//I guess it should be more like: message.split(" ").shift().join(" ");
// this will return you: "Something Here".

bot.action("stankotomic", "someone says: " + code);

您的最终代码:

bot.on("chat", function (channel, user, message, self) {
if(message.split(" ")[0] == "-say")
      var code = message.split(" ").shift().join(" ");
      bot.action("stankotomic", "someone says: " + code);
});
