如何使标签页在单击时保持在html中打开

我有一个带有标签的html页面。我希望在单击选项卡时打开选项卡下的内容。当我单击选项卡时，选项卡“打开”一秒钟，然后关闭。

使这些标签保持打开状态的正确方法是什么？我尝试了W3 Schools建议中列出的几种格式化选项卡html代码的方法，但我似乎仍然无法使其正常运行。

这是我的html代码：

function openTabs(evt, tabName) {
  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(tabName).style.display = "block";
  evt.currentTarget.className += " active";
}

.active,
.collapsible:hover {
  background-color: #f1f1f1;
}

.content {
  padding: 0 18px;
  display: none;
  overflow: hidden;
  background-color: #f1f1f1;
}

textarea {
  resize: none;
  overflow-y: scroll;
  overflow-x: scroll;
}

table,
th,
td {
  border: 1px solid black;
  border-collapse: collapse;
}

th,
td {
  padding: 2px;
}

th {
  text-align: left;
}


/* Style the tab */

.tab {
  overflow: hidden;
  border: 1px solid #fff;
  background-color: #fff;
  width: 595px
}


/* Style the buttons inside the tab */

.tab button {
  background-color: #fff;
  float: left;
  border: none;
  outline: none;
  cursor: pointer;
  padding: 12px 14px;
  transition: 0.3s;
  font-size: 15px;
}


/* Change background color of buttons on hover */

.tab button:hover {
  background-color: #ddd;
}


/* Create an active/current tablink class */

.tab button.active {
  background-color: #ccc;
}


/* Style the tab content */

.tabcontent {
  display: none;
  padding: 6px 12px;
  border: 1px solid #ccc;
  border-top: none;
}

查斯卡

默认情况下，<button>将在单击时提交表单。您可以<a>改用。

  <a class="tablinks" onclick="openTabs(event, 'Authorization')">Authorization</a>
  <a class="tablinks" onclick="openTabs(event, 'Header')">Header</a>
  <a class="tablinks" onclick="openTabs(event, 'Body')">Body</a>
