我已经实现了w3学校http://www.w3schools.com/w3css/w3css_slideshow.asp所示的幻灯片显示,但我对其“滑动”的顺序存在问题。我将自动幻灯片放映与幻灯片放映指示器结合在一起,但是当我加载页面时,订单是3,2,1。因此指示器从右向左移动。我自己也没有兴趣,所以希望有人可以帮助我。

setTimeout(carousel, 5000); // Change image every 5 seconds
plusDivs(1);

答案 0 :(得分:0)
我需要用showDivs(slideIndex)替换plusDivs(1)
if (date.getValue() == null) {
// Here --------^
