Update the picture displayed in the parent div when it is in an

My code currently changes the image when a parent div is in an active state, but I'm struggling to figure out how to revert it back to the original image when clicked again. I attempted to use 'return false' at the end of the script, but it didn't have the desired effect.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card egg" data-img="https://data.imgtools.co/output/tool/preview/400x400/face-extractor.png">
 <div class="card-image">
  <img src="https://play-lh.googleusercontent.com/IeNJWoKYx1waOhfWF6TiuSiWBLfqLb18lmZYXSgsH1fvb8v1IYiZr5aYWe0Gxu-pVZX3"/>
 </div>
</div>

$('.egg').click(function(){
  $(this).toggleClass("active");
  var new_src = $(this).attr('data-img');
  $(".card-image img").attr("src",new_src);
});

Answer №1

If you want to keep track of the original img src before toggling its state, simply update the same data attribute where you are storing the alternate image.

In this demonstration, I have optimized the way you select the img element by specifically targeting the img child within the clicked .egg div:

$('.egg').click(function() {  
  const new_src = $(this).attr('data-img');  
  const curr_src = $(this).find('.card-image img').attr('src');
  $(this).attr('data-img', curr_src);
  
  $(this).toggleClass("active");  
  $(this).find('.card-image img').attr("src", new_src);
});

<div class="card egg" data-img="https://data.imgtools.co/output/tool/preview/400x400/face-extractor.png">
  <div class="card-image">
    <img src="https://play-lh.googleusercontent.com/IeNJWoKYx1waOhfWF6TiuSiWBLfqLb18lmZYXSgsH1fvb8v1IYiZr5aYWe0Gxu-pVZX3" />
  </div>
