我有两个函数。第一个函数计算domcontentloaded和resize上的变量。第二个函数在domcontentloaded和scroll上触发。我需要第二个函数中第一个函数的3个变量来计算一些东西。我试图从第一个函数upme（）中获取返回变量数组，以便在第二个函数doso（）中使用-我收到此错误poss isn't defined at htmldocument.doso
java 脚本

document.addEventListener('DOMContentLoaded', upme);
  window.addEventListener('resize', upme);
  function upme()
  {
    var rome = document.getElementById("out-cmnt");
    var rect = rome.getBoundingClientRect();
    // console.log(rect.top, rect.right, rect.bottom, rect.left);
    var poss = rect.top + window.scrollY; var iwwr = window.innerWidth;
    var koss = rect.bottom + window.scrollY; var loss = koss - poss; 
    return [poss, loss];
  }
  document.addEventListener('DOMContentLoaded', doso);
  window.addEventListener('scroll', doso);
  function doso()
  {
    lopp = document.getElementById("Web_1920__1");
    hope = lopp.clientHeight; const meme = document.body.scrollHeight;
    const keke = hope/meme; const scsc = window.scrollY;
    var innr = window.innerHeight;
       
    var saka = upme(); // problem here calling 1st function
    var noss = poss - innr + loss; // problem here
  
    if(scsc > noss && window.matchMedia("(min-width: 765px)").matches)
    {
        // doing something
    }
  } 
  doso();

我怎样才能成功地把poss，loss，koss这些变量放到第二个函数doso（）-里面呢？请帮帮我。谢谢参与这个社区的每一个人。
