javascript - 元素符号列表不显示在所选容器中

标签 javascript html css

这些是我主页的完整代码。在这里，我遇到了我在 tabcontent 类中创建的列表似乎没有显示在输出/显示框中的情况。起初，我遇到列表不显示在元素符号中而是彼此相邻显示。因此，我为导航栏的 ul 和 li 修改/添加了类，它开始以列表形式显示。但是，元素符号列表似乎无法在 tabcontent 框中正确显示。

function openTest(evt, testName) {
  var i, tabcontent, tablinks;
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }
  document.getElementById(testName).style.display = "block";
  evt.currentTarget.className += " active";
}

document.getElementById("defaultOpen").click();
body {
  background-color: #d62929;
  font-family: Verdana, sans-serif;
  margin: 0;
}

.ul1 {
  list-style-type: none;

.li1 a,
.dropbtn {

使用display: inline-block;

function openTest(evt, testName) {
  var i, tabcontent, tablinks;
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }
  document.getElementById(testName).style.display = "block";
  evt.currentTarget.className += " active";
