如何为Web表单创建"全​​部检查"链接？

<form id="myForm">
 <label for="name">姓名：</label>
 <input type="text" id="name" name="name" required>
  <br>
 <label for="email">电子邮件：</label>
 <input type="email" id="email" name="email" required>
  <br>
 <label for="password">密码：</label>
 <input type="password" id="password" name="password" required>
  <br>
 <button type="button" onclick="validateForm()">全​​部检查</button>
</form>

function validateForm() {
  var name = document.getElementById("name").value;
  var email = document.getElementById("email").value;
  var password = document.getElementById("password").value;

  if (name == "" || email == "" || password == "") {
    alert("请填写所有字段");
    return false;
  }

  if (password.length < 8) {
    alert("密码长度必须至少为8个字符");
    return false;
  }

  // 在这里添加其他验证规则

  alert("表单验证成功！");
  return true;
}
