Javascript 为什么我的旋转木马会在用户交互中占据上风?
我在我的单页网站上制作了一个旋转木马,展示了我的一些摄影作品。我遇到的问题是,每当我点击其中一个箭头进入下一张图片——左或右,我都会立即被抓拍到页面顶部 我已经检查了CSS和JS,我似乎找不到任何原因来解释为什么会发生这种情况 HTML: JS:Javascript 为什么我的旋转木马会在用户交互中占据上风?,javascript,jquery,html,css,Javascript,Jquery,Html,Css,我在我的单页网站上制作了一个旋转木马,展示了我的一些摄影作品。我遇到的问题是,每当我点击其中一个箭头进入下一张图片——左或右,我都会立即被抓拍到页面顶部 我已经检查了CSS和JS,我似乎找不到任何原因来解释为什么会发生这种情况 HTML: JS: .exploration { height: 1100px; background-color: #ffffff; } .exploration .container { position: relative; to

您需要添加
e.preventDefault()代码>到您的onlick函数
检查
编辑
正如我刚才在评论部分所评论的,是href=“#”
导致页面跳转到顶部。因此,从技术上讲,如果删除achor标记e.preventDefault()代码>不是必需的。但最好保留它。在单击回调函数中添加一个参数(e),然后使用以下行阻止默认的post(带有href set的锚定标记有):
e.preventDefault();
像这样:
//Next Arrow Functionality
$('.arrow-next').click(function (e) {
var currentSlide = $('.active-slide');
var nextSlide = currentSlide.next();
var currentDot = $('.active-dot');
var nextDot = currentDot.next();
if (nextSlide.length == 0) {
nextSlide = $('.slide').first();
nextDot = $('.dot').first();
}
currentSlide.fadeOut(600).removeClass('active-slide');
nextSlide.fadeIn(600).addClass('active-slide');
currentDot.removeClass('active-dot');
nextDot.addClass('active-dot');
e.preventDefault();
});
//Previous Arrow Click Functionality
$('.arrow-prev').click(function (e) {
var currentSlide = $('.active-slide');
var prevSlide = currentSlide.prev();
var currentDot = $('.active-dot');
var prevDot = currentDot.prev();
if (prevSlide.length == 0) {
prevSlide = $('.slide').last();
prevDot = $('.dot').last();
}
currentSlide.fadeOut(600).removeClass('active-slide');
prevSlide.fadeIn(600).addClass('active-slide');
currentDot.removeClass('active-dot');
prevDot.addClass('active-dot');
e.preventDefault();
});
非常感谢你。我查看了e.preventDefault,得到了这样的描述:“如果调用此方法,则不会触发事件的默认操作。”。那么,根据这个定义,什么是导致问题的默认操作,以便我将来可以知道?href=“#”导致页面跳转到top@R4nc1d总结得很完美,+1对于你的小提琴,我有点懒:)
