    height:30px;
    overflow:hidden;
    }

</style>
<script>
$(function() {
  $('#div div').click(function() {
    var elem = $(this);
    var style = elem.css('background-image');
    if(/h\.jpg/.test(style)) {
      elem.css('background-image', style.replace(/h\.jpg/, '.jpg'));
    } else {
      elem.css('background-image', style.replace(/\.jpg/, 'h.jpg'));
    }
  });
});
</script>
</head>

<body>

    <div id="div">
        <div class="kat1 changing"></div>

为什么要在JavaScript中使用此功能?另一种选择是使用CSS类来简化过程:

$(function() {
  $('#div div').click(function() {
    $(this).toggleClass('active');
  });
});

CSS:

.kat1 {
    background-image:url(ikoniceKategorije/07.jpg);
    width:30px;
    height:30px;
    float:left;
}
.kat1:hover,
.kat1.active {
    background-image:url(ikoniceKategorije/07h.jpg);
}
