不太确定如何为问题加上标题。尽管如此,请考虑以下陈述

if (messageOne || messageTwo || messageThree || messageFour) {
  // do something here ...
 }

您将如何获取和使用遇到的信息?例如
if (messageOne || messageTwo || messageThree || messageFour) {
  console.log(messageOne) // <-- but rather than hardcoding messageOne I want to be able to grab whichever one is executed
 }

如果问题措辞不佳,我们深表歉意,如有必要可以澄清。

谢谢!

最佳答案

您可以使用

let result = messageOne || messageTwo || messageThree || messageFour;

let messageOne = null;
let messageTwo = null;
let messageThree = null;
let messageFour = "4";

let result = messageOne || messageTwo || messageThree || messageFour;

console.log(result);
