How can I dynamically change the image src in JavaScript and only display it after it’s fully loaded using javascript load image logic?

If you’re already using jQuery in your project and want a cleaner way to handle image loading, this method might feel more intuitive. You can directly attach a .on("load") event like this:

function changeImage(newSrc) {
  const $img = $("#id1");
  $("#loader").show();
  $img.hide();

  $img.off("load").on("load", function () {
    $("#loader").hide();
    $(this).show();
  }).attr("src", newSrc);
}

This makes sure you’re not stacking old onload handlers and keeps the logic neat, perfect for jQuery-based workflows.
