如何拿到这段 js 的执行结果?

代码如下,简单说下个人需求,主要想拿到 204 行 return 的值。

我尝试在代码首部定义全局变量 tmp ,然后在 203-204 行之间,在值返回之前赋值给全局变量 tmp ,然后执行完 CQjMxzxLaXGTrtvnVcFE 函数后,打印 tmp 是 undefined ,不明白白为什么拿不到返回值?

function CQjMxzxLaXGTrtvnVcFE() {

浏览器的话可以打断点看一下。也可以修改代码,然后覆盖远程的 js 文件

@jishuliu 断点打了,不用在意混淆。在浏览器中 console.log()是能正常出值的

@lzj724 额,好吧。不知道什么混淆的,我只知道这是个动态 js 每次请求回来的代码变量都会改变

小学问题 你能找到 204 行是哪一行吗

因为这些代码并不是同步执行的,里面有 setTimeout ,也就是说你 console.log()的时候 temp 还没有被赋值,可以尝试给 console 也加个 setTimeout
setTimeout(()=>{
console.error(tmp)
},1000)

@nekochyan 感谢大佬,加上延迟后,确实可以拿到值了
