我想在猫头鹰轮播中为每个轮播项目设置动画,就像进度条一样,我正在为动画使用简单的JQuery函数,这被称为onChange事件。但是问题是,在更改HTML结构之前会调用该函数。
点CSS:
--with-ca-path
JS
.owl-theme .owl-dots .owl-dot{
-webkit-border-radius: 0;
-moz-border-radius: 0;
border-radius: 0;
width: 100px;
height: 5px;
margin-left: 2px;
margin-right: 2px;
background: #ccc;
border:none;
}
.owl-theme .owl-dots .owl-dot span {
margin: 0;
background: white;
width:0;
-webkit-border-radius: 0;
-moz-border-radius: 0;
height: 5px;
}
.owl-theme .owl-dots .owl-dot.active span {
background: white;
width:0px;
}
仅当在下一个项目上更改轮播时,此代码才有效,但对上一个点进行了动画处理。有什么办法,我如何“暂停”此JS,等到HTML结构更改后再调用此函数?

基本上,我将owl-theme类添加到了owl-carousel容器中。
此外,我删除了“ onChange”选项,并向猫头鹰实例添加了侦听器“ changed.owl.carousel”。
