Display the div with a class only when jQuery is present

Recently, I've been encountering some issues with toggling the visibility of elements. On a single page, there are two popups and my goal is to hide one popup if the other has a certain class applied to it.

<body class="home">
  <div class="popup main"></div>
  <div class="popup"></div>
</body>

To elaborate further, when .main popup exists within body.home, only this particular popup should be displayed while the other .popup element is hidden or removed entirely.

My attempted solution was:

if ($('.home').find('.main')) {
     $('.home').find('.main').show();
     $('.home').find('.popup').remove();
}

Unfortunately, this approach did not yield the desired results because in certain scenarios, there might exist code containing only one popup block like so:

<body class="home">
  <div class="popup"></div>
</body>

Answer №1

Give this a shot,

if($(".modal").hasClass('active')){
   $(".modal").hide();
   $(".active").show();
 }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<body class="landing">
  <div class="modal active">active</div>
  <div class="modal">inactive</div>

Answer №2

$( '.homepage .popup' ).not( ".primary" ).delete();

Answer №3

Here is a simplified version for you to consider:

const showPopup = () => {
    if($('.main.popup').length){
        $('.popup.main').show().siblings('.popup:not(.main)').remove();
    } else {
        $('.popup').show();
    }
};

showPopup();

The code above provides a concise way to achieve the same functionality as the initial code block shown.

Answer №4

To toggle the visibility of an element, you can utilize the functions jQuery.hide() or jQuery.show(). However, be mindful that once you use jQuery.remove(), the element will be permanently deleted from the DOM tree and cannot be toggled back.

Answer №5

Verify using the hasClass() method

if ($('.home .popup').hasClass('main')) {
  $('.home .popup').hide();
  $('.home .main').show();
}

This script will hide all popups and then display only those with the .main class.

Edit

Unfortunately, this code does not work as intended when there is only one child in the .home element. Consider using CSS to resolve this issue

.home .popup:not(.main) {
  display: none;
}
.home .popup:only-child {
  display: block !important;
}

By utilizing this CSS code, you can easily manage visibility by adding or removing the .main class.
