我需要一点帮助。我正在尝试使用Bootstrap分页为我的bxslider横幅,我成功地设法将它们组合起来。现在我需要的是申请一个活跃的课程。在当前页码中。我正在尝试使用选项' onSlideAfter'但我不知道如何获取当前页面。
这是我的分页代码:
<div class="pull-right">
<div id="bx-pager">
<nav>
<ul class="pagination">
<li><a href="#" id="slider-prev"><span class="sr-only">Previous</span></a></li>
<li><a data-slide-index="0" href="">1</a></li>
<li><a data-slide-index="1" href="">2</a></li>
<li><a data-slide-index="2" href="">3</a></li>
<li><a data-slide-index="3" href="">4</a></li>
<li><a href="#" id="slider-next"><span class="sr-only">Next</span></a></li>
</ul>
</nav>
</div>
</div>
<div class="clearfix"></div>
这是我的js:
$('.bxslider').bxSlider({
auto: false,
autoControls: false,
captions: false,
responsive: true,
useCSS: false,
speed: 2000,
controls: true,
pager: true,
mode: 'fade',
slideMargin: 10,
pause: 10000,
easing: 'ease-in',
nextSelector: '#slider-next',
prevSelector: '#slider-prev',
pagerCustom: '#bx-pager',
onSlideAfter: function() {
alert('yehey new slide');
//dont know how to apply a class to the current page number
}
});
在我的CSS中我想添加一个这样的类
.page_active { color: maroon; }
我该怎么做?
答案 0 :(得分:1)
onSlideAfer
回调有3个参数function($slideElement, oldIndex, newIndex)
,您可以使用newIndex
确定页码,addClass
来li
。
尝试,(未经测试,添加一个小提琴,以便我们可以尝试一下)
$('ul.pagination li a[data-slide-index='+ newIndex +']').addClass('page_active');
见下面的演示,它确实运作良好,
$('.bxslider').bxSlider({
auto: false,
autoControls: false,
captions: false,
responsive: true,
useCSS: false,
speed: 2000,
controls: true,
pager: true,
mode: 'fade',
slideMargin: 10,
pause: 10000,
easing: 'ease-in',
nextSelector: '#slider-next',
prevSelector: '#slider-prev',
pagerCustom: '#bx-pager',
onSlideAfter: function($slideElement, oldIndex, newIndex) {
$('ul.pagination li a').removeClass('page_active').filter('[data-slide-index='+ newIndex +']').addClass('page_active');
}
});

.page_active {
color: maroon;
border: 1px solid maroon;
padding: 2px;
}
.pagination li { display: inline-block; margin: 2px; list-style: none; }
