javascript - 选择后隐藏单选按钮并在新 div 中显示所选值

问题描述

在此处输入图像描述一旦用户单击列表中的特定单选按钮，则整个单选按钮列表必须隐藏，并且所选单选按钮值必须显示在新 div 中，如右下角的“尝试演示”按钮所示“ https://collect.chat/ ”网站页面

<p class="chat-message">Which course you want to choose?
<label class="container">Course 1
<input type="radio" name="co1"value="course 1">
<span class="checkmark"></span></label>

<label class="container">Course 2
<input type="radio"  name="co2"value="course 2">
<span class="checkmark"></span></label>

<label class="container">Course 3
<input type="radio"  name="co3"value="course 3">
<span class="checkmark"></span></label>

<label class="container">Course 4
<input type="radio"  name="co4"value="course 4">
<span class="checkmark"></span></label> 

</p>

<div class="chat self">
<p class="chat-message"><span id="result"></span></p>
</div>

<script>
  document.mainForm.onclick = function()
  {
  var radVal = document.mainForm.rads.value;
  result.innerHTML = 'The course i want is'+radVal;
  }
 </script>

我希望单选按钮一旦选择就必须隐藏，并且选择的值必须显示在单独的 div 中

如图所示，单选按钮一旦被选中就会消失
