Trying to do a simple search and image load page for my website. It works great on the first click, but the image doesn't refresh when I enter a new search query.


<title>Animal Testing</title>

<script type="text/javascript" src="js/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="js/jquery-ui-1.8.20.custom.min.js"></script>

<style type="text/css" media="screen">
  BODY { margin: 10px; padding: 0; font: 1em "Trebuchet MS", verdana, arial, sans-serif; font-size: 100%; }
  H1 { margin-bottom: 2px; }

  DIV#loader {
      border: 1px solid #ccc;
      width: 700px;
      height: 580px;
      overflow: hidden;

  DIV#loader.loading {
      background: url(spinner.gif) no-repeat center center;

<script type="text/javascript">
  $(document).ready(function() {

  $('#searchButton').click(function() {
    var $currentAnimal = null; 
    $currentAnimal = $("#animal").val(); 
    var img = new Image();    
    $(img).load(function () {
      //$(this).css('display', 'none'); // .hide() doesn't work in Safari when the element isn't on the DOM already
    }).error(function () {
      // notify the user that the image could not be loaded
    }).attr('src', '' + $currentAnimal + '');  




<input type="text" id="animal" name="animal" value="Enter an animal">
<input type="button" id="searchButton" value="Enter">

<div id="preloader">
This is shown before the click, and will be hidden when the box is clicked

<div id="loader" class="loading"></div>


I thought breaking up and resigning the loading class would work, but it doesn't.

var img = new Image();
    if (! $('#loader').hasClass('loading')) {
      $img = null;
