我需要添加一个消息框和电子邮件文本框，并在msgresults标记中显示表单中的所有内容

<form id="myForm">
  <label for="message">消息：</label>
  <input type="text" id="message" name="message"><br><br>
  
  <label for="email">电子邮件：</label>
  <input type="email" id="email" name="email"><br><br>
  
  <input type="submit" value="提交" onclick="handleSubmit(event)">
</form>

<p id="msgresults"></p>

function handleSubmit(event) {
  event.preventDefault(); // 阻止表单默认提交行为
  
  var message = document.getElementById("message").value;
  var email = document.getElementById("email").value;
  
  var result = "消息：" + message + "<br>电子邮件：" + email;
  
  document.getElementById("msgresults").innerHTML = result;
}
