Question

我想知道是否有一种方法可以让我的for循环在第5次循环之后打印出语句而不是调用它6次并使用我的if语句停止在5。

有没有更有效的方法来实现这一目标？感谢。

let str = '--3c8a15bdc66e76b5 Content-Type: text/plain X-Primitive: integer 8487823278258687528 --3c8a15bdc66e76b5-- --3c8a15bdc66e76b5 Content-Type: text/plain X-Primitive: integer 14918370877051183774 --3c8a15bdc66e76b5-- .'

console.log(str.match(/\b\d+\b/g));

您可以迭代到5而不是6并将消息打印出循环：
