javascript - 在 LazyLoad 之后在 OWL Carousel 上添加类

Question

我正在使用OWL Carousel ，尝试添加类 .border-red至<div class="item">在lazyLoad之后，表示在lazyLoad之后调用此函数afterLazyLoad

示例:$(".item").addClass("border-red");当延迟加载时。表示添加类函数在OWLCarousel的lazyLoaded之后执行。

JS

$(document).ready(function() {

$("#owl-demo").owlCarousel({
items : 4,
lazyLoad : true,
navigation : true
});

});

HTML

<div id="owl-demo" class="owl-carousel">
    <div class="item"><img class="lazyOwl" data-src="assets/owl1.jpg" alt="Lazy Owl Image"></div>
    <div class="item"><img class="lazyOwl" data-src="assets/owl1.jpg" alt="Lazy Owl Image"></div>
    <div class="item"><img class="lazyOwl" data-src="assets/owl2.jpg" alt="Lazy Owl Image"></div>
    <div class="item"><img class="lazyOwl" data-src="assets/owl3.jpg" alt="Lazy Owl Image"></div>
    <div class="item"><img class="lazyOwl" data-src="assets/owl5.jpg" alt="Lazy Owl Image"></div>
</div>

如何添加类函数在OWLCarousel的lazyLoaded之后执行？

Answer 1

试试这个:

$(document).ready(function() {

   $("#owl-demo").owlCarousel({
      items : 4,
      lazyLoad : true,
      navigation : true,
      afterLazyLoad: function(elem){
          $(elem).addClass("border-red");
      }
   });

});

这里afterLazyLoad是一个回调函数
