javascript - 按钮定位在完全错误的位置

我有一个包含 2 个不同部分的网页。每个都是视口(viewport)的高度。一个在中央有一个“工作”按钮。单击此按钮后，它会消失，一些链接会出现在原来的位置。同样的事情适用于下一节。

我正在尝试添加重置功能以删除链接并重新添加按钮。我最初试图让一个按钮重置所有部分，但在这不起作用之后，我现在正在尝试为每个部分制作一个单独的按钮。

我已经这样做了，但我的问题是第二部分的重置按钮出现在与第一部分相同的位置。两者都应出现在各自部分的右下角。

function openSites(categoryType) {
  if (categoryType == "work") {
    var sites = document.getElementById("workSites");
    var button = document.getElementById("workButton");
  } else if (categoryType == "other") {
    var sites = document.getElementById("otherSites");
    var button = document.getElementById("otherButton");
  }
  sites.classList.add("show");
  sites.classList.remove("hide");
  button.classList.add("hide");
}

function reset(categoryType) {
  if (categoryType == "work") {
    var sites = document.getElementById("workSites");
    var button = document.getElementById("workButton");
  } else if (categoryType == "other") {
    var sites = document.getElementById("otherSites");
    var button = document.getElementById("otherButton");
  }
  sites.classList.remove("show");
  sites.classList.add("hide");
  button.classList.remove("hide");
}

function betterReset() {
  for (category in document.getElementsByClassName("category-container")) {
    document.write(category);
  }
}

最佳答案

你正在给你的重置按钮一个 position:absolute 。这使它们采用相对于具有 position:relative 的下一个父级的 right 和 bottom 的值。在这种情况下是 body 标签。

要解决此问题，请将 position:relative 添加到您的父 div。

#workSites,
#otherSites {
  position: relative;
}

希望这有帮助:>

                if (categoryType == "work") {
                    var sites = document.getElementById("workSites");
                    var button = document.getElementById("workButton");
                } else if (categoryType == "other") {
                    var sites = document.getElementById("otherSites");
                    var button = document.getElementById("otherButton");
                }
                sites.classList.add("show");
