javascript - 有没有办法在 JavaScript 或 jQuery 中的单击事件中调用特定的幻灯片图像

Question

我确实设法在点击时获取轮播中的上一张图像，但我无法指定“数据幻灯片到”图像

这是单击时获取上一张图像的代码

$("#header").carousel('prev');

但是在实现第二个时我没有得到任何回应

$("#header").carousel($(this).data('slide-to',0));

Answer 1

function gotoSlide(number){
   $(".carousel").carousel(number);
}
