在bxslider中,我想在当前幻灯片上添加一个类

Question

我想在当前可见幻灯片上添加一个额外的类,我没有太多关于jquery的知识,我正在通过以下代码来尝试它.

 $(document).ready(function(){
     $('#slider1').bxSlider({
        pager: 'true'
     });
 $(currentSlide).addClass('active-slide');
     return false;
 });    

Answer 1

要在第一个可见幻灯片上添加类,您必须调用onSliderLoad.然后使用onSlideAfter调用继续添加和删除active-slide类.

onSlideAfter: function (currentSlideNumber, totalSlideQty, currentSlideHtmlObject) {
    $('.active-slide').removeClass('active-slide');
    $('.bxslider>li').eq(currentSlideHtmlObject + 1).addClass('active-slide')
},
onSliderLoad: function () {
    $('.bxslider>li').eq(1).addClass('active-slide')
},

    var slider=$('#slider1').bxSlider({
     pager: 'true',
   onBeforeSlide: function(currentSlide, totalSlides, currentSlideHtmlObject){
        $('.pager').removeClass('active-slide');   
         $(currentSlideHtmlObject).addClass('active-slide');
 //     $('#sddf').html('<p class="check">Slide index ' + currentSlide + ' of ' + totalSlides + ' total slides has completed.');
    }
});
