你好，首先你要調用

<script?src="js/myfocus-2.0.1.min.js"?type="text/javascript"></script>
<script?src="js/mf-pattern/mF_fancy.js"></script>
<link?rel="stylesheet"?href="js/mf-pattern/mF_fancy.css"?type="text/css"?/>
<script>

然后

<div?class="ad"?id="picBox">
????	<div?class="loading"><img?src="images/loading.gif"?/></div>
????	<div?class="pic">
??????????<ul>
??????????????<li><img?src="images/ad2.jpg"?/></li>
??????????????<li><img?src="images/ad3.jpg"?/></li>
??????????????<li><img?src="images/ad4.jpg"?/></li>
??????????</ul>
????????</div>
????</div>

最后才是這個

<script>
myFocus.set({id:'picBox'});
</script>

你對比一下 缺少什么
