如何使用javascript根据下拉选择创建多个选项卡？

Question

我发布这个问题是因为我在任何地方都找不到明确的答案或方法。 我想要做的是，我创建了一个名为“底盘数”的下拉菜单。 现在，根据在此字段中选择的下拉列表（“1”或“2”），如果用户在下拉列表中选择“1”，我想要一个标签“UUT1”，如果用户在下拉列表中选择“1”，我想要两个标签“UUT1”和“UUT2”用户在下拉列表中选择“2”。 然后单击 UUT1 和 UUT2 选项卡，如果要显示我在下面定义的模板。 在此处附加 html 部分以及可能我正在寻找的屏幕截图。

请参考以下代码。 也请在评论中找到小提琴链接。 如果您需要更多帮助，请创建示例的小提琴。

<h2>Tabs</h2>
<select id="tabsToDisplay">
<option value="1">1</option>
<option value="2">2</option>
</select><br/><br/>

<div class="tab">
  <button class="tablinks" id= "tab1btn" >tab1</button>
  <button class="tablinks" id= "tab2btn" >tab2</button>  
</div>

<div id="tab1" class="tabcontent">
  <h3>Tab1</h3>
  <p>You selected tab1</p>
</div>

<div id="tab2" class="tabcontent">
  <h3>Tab2</h3>
  <p>You selected tab2</p>
</div>
// A $( document ).ready() block.
$( document ).ready(function() {  
 function displaySelectedTabs(selectedNumber){
 switch(selectedNumber){
  case "1":
  $("#tab2btn").hide();
  $("#tab2").hide();      
  break;
  case "2":
  $("#tab2btn").show();
  break;  
 }
}
var selectedNumber = $("#tabsToDisplay").val();
displaySelectedTabs(selectedNumber);
 function tabClick(evt, cityName) {
  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(cityName).style.display = "block";
  evt.currentTarget.className += " active";
}
$("#tab1btn" ).click(function() {
  tabClick(event, 'tab1');
});
$("#tab2btn" ).click(function() {
  tabClick(event, 'tab2');
});
$( "#tabsToDisplay" ).change(function() {
  var selectedNumber = $("#tabsToDisplay").val();
displaySelectedTabs(selectedNumber);
});    
});
