Question

我想这样做，以便它会在某些单词之后抓取某些信息，并例如在某些单词处停止

我只是不知道从哪里开始。

我看了看别人的所作所为，然后试图把它自己拿出来，但不知道怎么做。

首先在竖线处分割以获取字符串的每个部分（String.split()）。然后，遍历子字符串（"Loops and iteration"）并检查每个字符串（String.startsWith()）的开头，并根据需要处理结果参数。

const str = 'ss!submit | WIYISD: hopefully | SHIWW: this code | WDYWTA: will | SPN: help you!';

const split = str.split(' | ').slice(1); // Also removing the command portion.

const args = {};

for (let i = 0; i < split.length; i++) {
  const arg = split[i];
  
  if (arg.startsWith('WIYISD: ')) args.WIYISD = arg.replace('WIYISD: ', '');
  else if (arg.startsWith('SHIWW: ')) args.SHIWW = arg.replace('SHIWW: ', '');
  else if (arg.startsWith('WDYWTA: ')) args.WDYWTA = arg.replace('WDYWTA: ', '');
  else if (arg.startsWith('SPN: ')) args.SPN = arg.replace('SPN: ', '');
  else {
    console.error('Check your syntax.'); // Send an error message instead...
    break; // ...and return (illegal in this context).
  }
}

console.log(args); // The result in this example is an object, not an array.

将此整合到您的消息事件中...

// const bot = new Discord.Client();
const prefix = 'ss!';

bot.on('message', message => {
  // Stop if the author is a bot or the message doesn't start with the prefix.
  if (message.author.bot || !message.content.startsWith(prefix)) return;

  // This is a very crude setup. Consider a command handler to keep the code organized.
  if (message.content.startsWith(`${prefix}submit `)) {
    const split = message.content.split(' | ').slice(1);

    const args = {};

    for (let i = 0; i < split.length; i++) {
      const arg = split[i];

      if (arg.startsWith('WIYISD: ')) args.WIYISD = arg.replace('WIYISD: ', '');
      else if (arg.startsWith('SHIWW: ')) args.SHIWW = arg.replace('SHIWW: ', '');
      else if (arg.startsWith('WDYWTA: ')) args.WDYWTA = arg.replace('WDYWTA: ', '');
      else if (arg.startsWith('SPN: ')) args.SPN = arg.replace('SPN: ', '');
      else {
        return message.channel.send(':x: Invalid syntax.')
          .catch(console.error); // Make sure the catch rejected promises.
      }
    }

    // Use 'args' as you wish.
  }
});
