Display and conceal definition terms and descriptions upon hovering

I have successfully implemented a toggle class for dd & dt, but now I want to enable show and hide functionality on hover. How can I achieve this?

<div class="navigation">
    <dt><?php echo $this->__($_filter->getName()) ?></dt>
    <dd><?php echo $_filter->getHtml() ?></dd>
</div>

<script type="text/javascript" src="https://code.jquery.com/jquery-1.11.3.js"></script>
<script type="text/javascript">
jQuery=$.noConflict();
jQuery(document).ready(function() {
    jQuery('.navigation dd').hide(); 

    jQuery('.navigation dt').hover(
        function(){ 
            jQuery(this).next('dd').slideDown('slow');
            jQuery(this).addClass('glace_navigationlayer-collapsed'); 
        },
        function(){ 
            jQuery(this).next('dd').slideUp('slow');
            jQuery(this).removeClass('glace_navigationlayer-collapsed'); 
        }
    );

}); 
</script>
javascript

Answer №1

A more efficient way to display and hide elements on hover is by utilizing CSS instead of Javascript.

.navigation dt:hover + dd {
  display: none;
}


/*You can ignore this code*/
.navigation dt {
  background-color: red;
}
.navigation dd {
  background-color: green;
}
<div class="navigation">
  <dt>dt</dt>
  <dd>dd</dd>
</div>

The + selector targets the adjacent sibling, so remember to place dd after dt.

Answer №2

The solution should be simple and straightforward. I'm not sure why the code provided below is not functioning as expected.

var $ = jQuery;
$(document).ready(function() {
  $('.navigation dd').hide(); 

  $('.navigation dt').hover(function(){ 
    $(this).next('dd').stop(true).slideToggle('slow');
    $(this).toggleClass('glace_navigationlayer-collapsed'); 
  });
}); 
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="navigation">
  <dt>YOUR DT</dt>
  <dd>YOUR DD</dd>
</div>

Answer №3

.hiddenClass{
   visibility: hidden; 
 }

Instead of using the traditional .hover() method, you can utilize the built-in function...this function requires two actions to be defined - the first one for mouse-enter event and the second one for mouse-leave event.

$('.menu').hover(addHiddenClass, removeHiddenClass)

function addHiddenClass(){
     $('.menu').addClass('hiddenClass')
}

function removeHiddenClass(){
     $('.menu').removeClass('hiddenClass')
}

Answer №4

For a solution, you can experiment with using mouseenter and mouseleave.

jQuery('.navigation dd').hide();
jQuery('.navigation dt').on('mouseenter mouseleave', function() {
  jQuery(this).next('dd').slideToggle('slow');
  jQuery(this).toggleClass('glace_navigationlayer-collapsed');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<dl class="navigation">
  <dt>Chrome</dt>
  <dd>by Google</dd>
  <dt>Safari</dt>
  <dd>by Apple</dd>
<dl>
