我正在使用OpenSource“unlider”并且使用代码来启用按钮以“滑动”到一个或另一个图像。 此处提供的代码：http:www.unslider.com“添加上一行/下一行”无效。
我正在提供我正在使用的css规则和html标签：
div class="wrapper">
<div id="banner_promos">
<!-- Botones del banner e imagen -->
<div id ="left_arrow">
<a href="#" class="unslider-arrow prev"><img src="images/arrow-left-02.png" width="40" height="40"></a>
</div>
<div id ="right_arrow">
<a href="#" class="unslider-arrow next"><img src="images/arrow-right-01.png" width="40" height="40"></a>
</div>
<div id="img_banner" class="banner">
<script src="pages/scripts/slider.js"></script>
<ul>
<li>
<img src="images/promos/pepes_promo.jpg" width="700" height="350"/>
</li>
<li>
<img src="images/promos/guidos_promo.jpg" width="700" height="350"/>
</li>
</ul>
</div>
</div>
这是css规则：
#left_arrow, #right_arrow{
margin-top:140;
}
#left_arrow{
float:left;
}
#right_arrow{
float:right;
}
#img_banner{
/*float:left;
*/
}
.banner { position: relative; overflow: auto; top: 0px }
.banner li { list-style: none; }
.banner ul li { float: left; }
使用的代码如下：
var unslider = $('.banner').unslider();
$('.unslider-arrow').click(function(event) {
alert('entra');
event.preventDefault();
if ($(this).hasClass('next')) {
unslider.data('unslider')['next']();
} else {
unslider.data('unslider')['prev']();
};
});
