Jquery show/hide password

问题

Below Jquery is working fine but How could I shorten this Jquery? I have to show and hide the password for password and confirmed password? 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();
});

Here is one-of-the ways, how you can shorten your code:

$(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>

you can use only one button to control.

• js：

```

$('.showOrHide').click(function(e){
    var target = e.currentTarget
    $(target).hasClass('show')?hidePassword($(target)):showPassword($(target))
})
function hidePassword(e){
    e.removeClass('show').addClass('hide')
    e.prev('input').attr('type','password')
}
function showPassword(e){
    e.removeClass('hide').addClass('show')
    e.prev('input').attr('type','text')
}

html：

```

<input type="text" value="123456">
<button class="showOrHide show">click</button>

```

style:

```

.show{
    /*css you want */
    color: blue
}
.hide{
    /*css you want */
    color: red
}

```

This is the shortest i think you can get

$(".confirm-password-showhide .trigger-password, .password-showhide .trigger-password").click(function() {
  var c = $(this).parent().attr("class").replace("-showhide", "");
  var obj = $("#" + (c.indexOf("confirm") > -1 ? "confirmPassword" : "password"));
  obj.attr("type", obj.attr("type") == "text" ? "password" : "text");
  $(this).text($(this).text() == "hide" ? "show" : "hide");
});

I've also removed the "hide" span from each of the passwords.

$(".confirm-password-showhide .trigger-password, .password-showhide .trigger-password").click(function() {
  var c = $(this).parent().attr("class").replace("-showhide", "");
  var obj = $("#" + (c.indexOf("confirm") > -1 ? "confirmPassword" : "password"));
  obj.attr("type", obj.attr("type") == "text" ? "password" : "text");
  $(this).text($(this).text() == "hide" ? "show" : "hide");
});

<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="trigger-password">Show</span></span>
  </li>
  <li><input type="password" name="password" id="confirmPassword"> <span class="confirm-password-showhide"><span class="trigger-password">Show</span></span>
  </li>
</ul>

show/Hide password function

function togglePassword($element){
    var newtype=$element.prop('type')=='password'?'text':'password';
    $element.prop('type',newtype);
}
$(document).ready(function() {
      $('#showUserNewPass').change(function(){
          togglePassword($('#userNewPass'));
          togglePassword($('#confirmNewPassword'));
      });
});
