<form id="myForm">
  <input type="text" name="name" placeholder="姓名">
  <input type="email" name="email" placeholder="邮箱">
  <input type="checkbox" name="subscribe" value="1"> 订阅邮件
  <select name="gender">
    <option value="male">男</option>
    <option value="female">女</option>
  </select>
  <button type="submit">提交</button>
</form>

var form = document.getElementById("myForm");
form.addEventListener("submit", function(event) {
  event.preventDefault(); // 阻止表单默认提交行为

  // 提取表单中的值
  var name = form.elements["name"].value;
  var email = form.elements["email"].value;
  var subscribe = form.elements["subscribe"].checked;
  var gender = form.elements["gender"].value;

  // 执行其他操作，例如发送数据给服务器或进行验证

  // 清空表单
  form.reset();
});
