如何通过onSubmit事件处理程序提交表单

<form onsubmit="submitForm(event)">
  <label for="name">姓名:</label>
  <input type="text" id="name" name="name" required>
  <br><br>
  <label for="email">邮箱:</label>
  <input type="email" id="email" name="email" required>
  <br><br>
  <input type="submit" value="提交">
</form>

<script>
function submitForm(event) {
  event.preventDefault(); // 阻止表单默认提交行为

  // 获取表单数据
  var name = document.getElementById("name").value;
  var email = document.getElementById("email").value;

  // 处理表单数据
  if (name && email) {
    // 在此处可以执行数据验证、存储或发送到服务器等操作
    alert("提交成功！姓名：" + name + "，邮箱：" + email);
    document.getElementById("name").value = "";
    document.getElementById("email").value = "";
  } else {
    // 显示错误信息
    alert("请填写完整的姓名和邮箱！");
  }
}
</script>
