取消滚动工具栏的脚本在chrome上的tampermonkey中起作用，而在Firefox上的greasmonkey中不起作用

如何解决取消滚动工具栏的脚本在chrome上的tampermonkey中起作用，而在Firefox上的greasmonkey中不起作用

我目前正在使用我在github上找到的脚本来“解除工具栏的锁定”（只是阻止CSS元素随页面滚动；不知道我是否使用了正确的术语）。它适用于chrome上的tampermonkey（尽管脚本页面上有错误），但不适用于Firefox中的greasmonkey。为什么在firefox中它不能与滑脂猴子一起使用，我该如何解决？

fixed_items = [];

function unfixAll() {
  Array.forEach(
    document.querySelectorAll("h1,h2,ul,ol,li,div,nav,header,footer"),function (el) {
      var style = window.getComputedStyle(el);
      if (style.position === "fixed" && style.top == "0px" &&
          !(style.display === "none" || style.visibility === "hidden"))
          /* Avoid unfixing JavaScript popups like Twitter's "confirm retweet" window */
      {
        fixed_items.push(el);
        //el.style.position = "static";
        el.style.visibility = "hidden";
        /* I tried using "absolute" in the past,but this breaks wordpress's footer.
           Using "static" breaks it too,but at least it doesn't get in the way. */
      }
    });
}

function fixBack()
{
  Array.forEach(
    fixed_items,function(el) {
      //el.style.position = "fixed";
      el.style.visibility = "";
    }
  )
  fixed_items = [];
}

function onScroll()
{
  if (window.scrollY > 0)
  {
    unfixAll();
  }
  else
  {
    fixBack();
  }
}

window.addEventListener("scroll",onScroll);

解决方法

它与chrome上的tampermonkey一起使用（尽管脚本页面上有错误），但与Firefox中的greasmonkey一起使用。

当我回答另一个脚本的查询时遇到类似的问题（参考：[FireMonkey] Request YT' JS script ad blocker。

脚本未声明变量，例如fixed_items = [];并以严格模式破坏脚本。

以下是相同的代码 ：（我尚未测试过）

// @description Removes "position: fixed" style from elements,unfixing "toolbars" and the such.
// @namespace   https://hasanyavuz.ozderya.net

(() => { // anonymous function wrapper,for error checking & limiting scope

let fixed_els = [];

function unfixAll() {

  document.querySelectorAll('h1,h2,ul,ol,li,div,nav,header,footer').forEach(el => {

    const style = window.getComputedStyle(el);
    if (style.position === 'fixed' && style.top == '0px' &&
        !(style.display === 'none' || style.visibility === 'hidden')) {
      // Avoid unfixing JavaScript popups like Twitter's "confirm retweet" window
      fixed_els.push(el);
      el.style.visibility = 'hidden';
      /* I tried using "absolute" in the past,but this breaks WordPress's footer.
         Using "static" breaks it too,but at least it doesn't get in the way. */
    }
  });
}

function fixBack() {

  fixed_els.forEach(el => el.style.visibility = '');
  fixed_els = [];
}

function onScroll() {

  window.scrollY > 0 ? unfixAll() : fixBack();
}

window.addEventListener('scroll',onScroll);

})();
