我正在使用Ariel Flesler的serialScroll脚本,并希望在活动或突出显示的项目中添加一个类,以便我可以使用CSS设置它。阅读the documentation我发现了通知触发器,但我不确定如何/是否可以用它来完成此任务。
这是我的代码:
的jQuery
jQuery(function( $ ){
$('#slideshow').serialScroll({
items:'li',
prev:'#screen2 a.prev',
next:'#screen2 a.next',
offset:-180,
start: 0,
duration:1200,
force:true,
stop:true,
lock:false,
cycle:false,
jump: true
});
});
HTML
<div id="screen2">
<div id="buttons">
<a class="prev" href="#">Previous</a>
<a class="next" href="#">Next</a>
<br class="clear" />
</div>
<div id="slideshow">
<ul>
<li><img src="http://www.stockvault.net/data/s/113497.jpg" /></li>
<li><img src="http://www.stockvault.net/data/s/100177.jpg" /></li>
<li><img src="http://www.stockvault.net/data/s/101916.jpg" /></li>

<li><img src="http://www.dreamstime.com/office-in-nature-thumb3256171.jpg" /></li>
<li><img src="http://www.dreamstime.com/nature-tree-thumb16030502.jpg" /></li>
<li><img src="http://www.dreamstime.com/gift-of-the-nature-thumb15977958.jpg" /></li>
<li><img src="http://www.dreamstime.com/nature-abstract-thumb3615419.jpg" /></li>
<li><img src="http://www.dreamstime.com/nature-path-in-forest-with-sunshine-thumb8241130.jpg" /></li>
<li><img src="http://www.dreamstime.com/nature-walk-thumb8436665.jpg" /></li>
<li><img src="http://www.dreamstime.com/save-the-nature-thumb15696583.jpg" /></li>
</ul>
</div>
</div>
我是否误解了通知触发器的功能?如果是这样,有没有其他方法来完成我所追求的目标?
答案 0 :(得分:3)
从插件示例页面,这里是如何使用onBefore:
onBefore:function( e, elem, $pane, $items, pos ){
/**
* 'this' is the triggered element
* e is the event object
* elem is the element we'll be scrolling to
* $pane is the element being scrolled
* $items is the items collection at this moment
* pos is the position of elem in the collection
* if it returns false, the event will be ignored
*/
//those arguments with a $ are jqueryfied, elem isn't.
}
在该函数中,您可以添加活动类,并使用onAfter函数从上一个元素中删除该类。
