Hide and reveal images on hover by using multiple images or links on a single webpage

Despite my efforts, I haven't been able to find exactly what I'm looking for. My current setup involves an image/content slider powered by Awkward Showcase. Within each slide, I want to incorporate a mouse-in/mouse-out effect that switches and hides images when the user hovers over text options. The JavaScript code I have in place is as follows:

$("#news-2, #news-3, #news-4, #news-5, #news-6").hide();

$("#newsitem-1, #newsitem-2, #newsitem-3, #newsitem-4, #newsitem-5, #newsitem-6").mouseover(function(){

    $(this).css('cursor', 'pointer');

    if($("#newsitem").val() != $(this).attr('id').replace('newsitem', 'news')){

        $("#news-1").hide();
        $("#news-2").hide();
        $("#news-3").hide();
        $("#news-4").hide();
        $("#news-5").hide();
        $("#news-6").hide();

        $("#newsitem").val($(this).attr('id').replace('newsitem', 'news'));

        var vid = $(this).attr('id').replace('newsitem', 'news');

        $("#" + vid).show();

    }

});

The HTML associated with this is structured like so:

<div id="showcase" class="showcase">

<div class="showcase-slide cs-1">
  <div class="showcase-content">
    <div class="cs-container">
      <div class="thumbs">
        <div id="news-1"><a href="/link"><img src="http://placehold.it/640x360/eeeeee/cccccc" border="0"></a></div>
        <div id="news-2" style="display: none;"><a href="/link"><img src="http://placehold.it/640x360/dddddd/dddddd" border="0"></a></div>
        <div id="news-3" style="display: none;"><a href="/link"><img src="http://placehold.it/640x360/cccccc/aaaaaa" border="0"></a></div>                 
      </div>

      <div class="cs-links">
        <h2>Link Title 1</h2>
        <ul>
          <li id="newsitem-1"><a href="#">Hover Change Image 1</a></li>
          <li id="newsitem-2"><a href="#">Hover Change Image 2</a></li>
          <li id="newsitem-3"><a href="#">Hover Change Image 3</a></li>
        </ul>
      </div>
    </div>         
  </div>
  <div class="showcase-thumbnail">
  <div class="showcase-thumbnail-caption">Caption Title</div>
  <div class="showcase-thumbnail-cover"></div>
  </div>
</div>

<div class="showcase-slide cs-2">
  <div class="showcase-content">
    <div class="cs-container">
      <div class="thumbs">
        <div id="news-4"><a href="/link"><img src="http://placehold.it/640x360/eeeeee/cccccc" border="0"></a></div>
        <div id="news-5" style="display: none;"><a href="/link"><img src="http://placehold.it/640x360/dddddd/dddddd" border="0"></a></div>
        <div id="news-6" style="display: none;"><a href="/link"><img src="http://placehold.it/640x360/cccccc/aaaaaa" border="0"></a></div>                 
      </div>

      <div class="cs-links">
        <h2>Link Title 2</h2>
        <ul>
          <li id="newsitem-4"><a href="#">Hover Change Image 1</a></li>
          <li id="newsitem-5"><a href="#">Hover Change Image 2</a></li>
          <li id="newsitem-6"><a href="#">Hover Change Image 3</a></li>
        </ul>
      </div>
    </div>         
  </div>
  <div class="showcase-thumbnail">
  <div class="showcase-thumbnail-caption">Restaurant TV</div>
  <div class="showcase-thumbnail-cover"></div>
  </div>
</div>

</div>

I would appreciate any suggestions or advice on making this more efficient. Additionally, do you have any insights into why this setup breaks after engaging the slide function?

Edit: To explain my use of IDs, they are necessary due to the one-to-one relationship between text and associated images.

Edit 2: When I switch the order of my JavaScript code, the functionality breaks. You can view a JSFiddle with the correct order here.

Answer №1

This particular function caught my attention because of its unique approach that I haven't seen before. One potential issue that stands out to me is the following code snippet:

var vid = $(this).attr('id').replace('newsitem', 'news');

Replacing an ID of an element that listens to an event may pose a problem, as the event can only occur once on that element. Subsequently, it may not be recognized when the ID is changed.

It is recommended to use web debugging tools like firebug or Chrome developer tools to set breakpoints and step through the code to identify why it is not functioning correctly.
