Question

我写了一个HTML表单，其中包含多个单选输入和几个文本框。

但是一旦单击“提交”按钮，我不知道如何使用Javascript显示输出。

我的目标是在同一页面中获得输出。

显示输出后，我想添加另一个Javascript函数，只需单击一下按钮即可复制输出。

感谢您的帮助。

这应该让您开始做事

function display() {
  document.getElementById("output").innerHTML = "";
  var inputs = document.getElementsByTagName("input");

  for (i = 0; i < inputs.length; i++) {
    if ((inputs[i].type = "radio")) {
      if (inputs[i].checked)
        document.getElementById("output").innerHTML +=
          inputs[i].value ;
    }
  }
}

Programming Language: 
    <input type="radio" name="java" value="Java">Java
    <input type="radio" name="javascript" value="Javascript">Javascript 
    <input type="radio" name="other" value="Others">Others 

<div id="output"></div> 


<button type="button" onclick="display()"> 
        Submit 
    </button>
