尝试使用html和javascript验证密码是否匹配

<form>
  <label for="password">密码：</label>
  <input type="password" id="password" required><br>
  <label for="confirmPassword">确认密码：</label>
  <input type="password" id="confirmPassword" required><br>
  <input type="submit" value="验证">
</form>

document.querySelector('form').addEventListener('submit', function(event) {
  event.preventDefault(); // 阻止表单默认提交行为
  var password = document.getElementById('password').value;
  var confirmPassword = document.getElementById('confirmPassword').value;
  
  // 调用密码匹配验证函数
  validatePassword(password, confirmPassword);
});

function validatePassword(password, confirmPassword) {
  if (password === confirmPassword) {
    alert('密码匹配成功！');
  } else {
    alert('密码不匹配，请重新输入！');
  }
}
