Jquery显示/隐藏密码

Question

下面的 Jquery 工作正常，但是我怎样才能缩短这个 Jquery？我必须显示和隐藏密码和确认密码吗？https://jsfiddle.net/c5cvLo54/1/

$(".password-showhide .show-password").click(function() {
    $("#password").attr("type", "text");
    $(".password-showhide .show-password").hide();
    $(".password-showhide .hide-password").show();
});
$(".password-showhide .hide-password").click(function() {
    $("#password").attr("type", "password");
    $(".password-showhide .hide-password").hide();
    $(".password-showhide .show-password").show();
});

$(".confirm-password-showhide .show-password").click(function() {
    $("#confirmPassword").attr("type", "text");
    $(".confirm-password-showhide .show-password").hide();
    $(".confirm-password-showhide .hide-password").show();
});
$(".confirm-password-showhide .hide-password").click(function() {
    $("#confirmPassword").attr("type", "password");
    $(".confirm-password-showhide .hide-password").hide();
    $(".confirm-password-showhide .show-password").show();
});

以下是缩短代码的方法之一：

$(document).ready(function() {

  $(".show-password, .hide-password").on('click', function() {
    var passwordId = $(this).parents('li:first').find('input').attr('id');
    if ($(this).hasClass('show-password')) {
      $("#" + passwordId).attr("type", "text");
      $(this).parent().find(".show-password").hide();
      $(this).parent().find(".hide-password").show();
    } else {
      $("#" + passwordId).attr("type", "password");
      $(this).parent().find(".hide-password").hide();
      $(this).parent().find(".show-password").show();
    }
  });
});

li {
  list-style: none
}

.hide-password {
  display: none
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
  <li>
    <input type="password" name="password" id="password" />
    <span class="password-showhide">
<span class="show-password">Show</span>
    <span class="hide-password">hide</span>
    </span>
    <li>
      <li>
        <input type="password" name="password" id="confirmPassword" />
        <span class="confirm-password-showhide">
<span class="show-password">Show</span>
        <span class="hide-password">hide</span>
        </span>
        <li>
</ul>
