调用jq

<script type="text/javascript">
$(document).ready(function(){
    // 焦点图片淡隐淡现
    $("#slider3").Xslider({
        affect:'fade',
        ctag: 'div'
    });
});
</script>

html部分

<div class="slider" id="slider3">
            <div class="conbox">
                <div style="position: absolute; z-index: 9; opacity: 1;"><a title="" href="#"><img src="images/b.jpg"></a></div>
