这里有一个更艰巨的挑战。

我正在使用这个 jQuery plugin一张专辑。每当用户单击图片时，我都想突出显示该项目。完成了!
下面是触发相册的函数:

现在，我想要的是每当用户单击下一个或上一个箭头时，第一个可见项目应该用边框突出显示。
可以使用适当的配置来完成这项工作吗？以下是插件文档的链接 http://sorgalla.com/projects/jcarousel/#Configuration
最佳答案
我添加了一个用户定义的类 current对于突出显示的图像，并根据具有此 current 的元素管理下一张或上一张图像的突出显示类，使用 2 个更多的点击事件，next 和 prev 按钮。
这是工作脚本:
$(document).ready(function(){
jQuery('#mycarousel').jcarousel({
scroll:2,
animation:'slow',
wrap:'last',
initCallback:function(){
$("#mycarousel li:eq(0)").css('border','2px solid gray');
$("#mycarousel li:eq(0)").addClass("current");
}
});
$("#mycarousel li").click(function(){
$("#mycarousel li").css('border','none');
$("#mycarousel li").removeClass('current');
$(this).css('border','2px solid gray');
$(this).addClass('current');
});
$(".jcarousel-next-horizontal").click(function(){
$(".current").css('border', 'none');
$(".current").next().css('border', '2px solid gray');
$(".current").removeClass('current').next().addClass('current');
});
$(".jcarousel-prev-horizontal").click(function(){
$(".current").css('border', 'none');
$(".current").prev().css('border', '2px solid gray');
$(".current").removeClass('current').prev().addClass('current');
});
});
