Discord.js | 拆分一条消息

Question

I'm pretty new to the development world, I wanted to practice doing JS, and I learned that Discord bots could be done in this language, I found it cool to practice.

My problem: I want to separate the command from the rest of the message. I managed to separate the command from a word, but when I enter several words, it does not work. This is what it does:

(!Command HELLO" will send "Command + Hello", but "!command HELLO HI" will not work)

 const PREFIX = "!"; bot.on('message', function(message) { if(message.content[0] === PREFIX) { let splitMessage = message.content.split(" "); if(splitMessage[0] === '!command') { if(splitMessage.length === 2) { message.channel.send('Command + ' + splitMessage[1]); } } } }); 

Thanks

Answer 1

 splitMessage[1]

that takes the second word from the splitted array. So with Command! Hello world Command! Hello world it will be Hello . You might want to take everything after the first element from the split Message like so:

splitMessage.slice(1)

that returns ["Hello", "World"] , so you just need to join it back to a string

 .join(" ")

How i would do that:

  const [command, ...args] = message.content.split(" ");

  switch(command){
    case "!Command":
       message.channel.send('Command + ' + args.join(" "));
    break;
    //....
  }

As I stated in the comment:

    const PREFIX = "!";
    bot.on('message', function(message) {
        if(message.content[0] === PREFIX) {
            let command = message.content.substring(message.content.indexOf(" ") + 1, message.content.length);
            message.channel.send('Command + ' + command);
        }
    });
