javascript - 在 JavaScript 中使用带有分隔符的字符串进行 split

Question

我需要从用户输入中提取命令和参数(Node.js)，例如用户可以编写以下情况之一:

g!p first video is good

g! play latest game was bad

g!play latest game was bad

第一种情况:command = "p"和 Args="first video is good .... to the end of the string"

在第二种情况下:command = "play"和 Args="latest game was .... to the end of the string"

...

const command = message.toLowerCase().split("!", 2).join("");
const Args = message.content.split(" ")[2];

if(command === 'play' or command === 'p'){........}

我尝试使用“!”进行分割功能但它不起作用

匹配 !，后跟零个或多个空格字符，然后匹配并捕获下一个单词(非空格字符)，然后使用不同的组来匹配并捕获其他所有内容:

const extract = (str) => {
  const match = str.match(/!\s*(\S+)\s+(.+)/);
  if (!match) {
    return 'No match';
  }
  const [, command, args] = match;
  console.log("Command:" + command, "Args:" + args);
};
extract('g!p first video is good');
extract('g! play latest game was bad');
extract('g!play latest game was bad');
