What is the best way to access the image src or id within a datalist using JavaScript?

I am trying to use JavaScript to retrieve the src or id of an image in a datalist. Below is a snippet of the code I am working with:

<script type="text/javascript">
          $(document).ready(function () {
              $('.productImage').mouseover(function () {
                  var imageUrl = $('.productImage').attr('src');
                  //alert(imageUrl);
                  $.ajax({
                     type: "POST",
                     url: "WebServiceVar.asmx/getVarImage",
                     contentType: "application/json; charset=utf-8",
                     dataType: "json",
                     data: "{'imageUrl':'" + imageUrl + "'}",
                     success: function (data) {
                     }
                  })
              });
          });
       </script>

When hovering over any image within the datalist, only "images/products/image1.png" is displayed by the alert(imageUrl) method, despite there being multiple images in the DataList.

Answer №1

To improve your code, consider including the following snippet.

 const imgUrl = $(this).attr('src');

By using this line of code within a mouseover event for an image hover, you can easily retrieve the current image source.
