如何通过按钮单击启动html表单，然后按钮消失，表单出现在屏幕上？

<button id="startButton">启动表单</button>

<form id="myForm" style="display: none;">
  <!-- 表单内容 -->
</form>

<script>
  var startButton = document.getElementById("startButton");
  var myForm = document.getElementById("myForm");

  startButton.addEventListener("click", function() {
    startButton.style.display = "none";
    myForm.style.display = "block";
  });
</script>
