如何解决javascript: onclick="scrollWin()" 无法按预期工作
除了用鼠标滚动外,我希望当您单击顶部的名称时,页面应自动向下滚动到页面底部并显示菜单。 问题是,使用我的 onclick="scrollWin()" 函数,页面向下滚动一毫秒,菜单出现,但随后页面自行向上滚动一点,菜单再次消失,而当页面出现时它应该留在那里已滚动到底部。我认为问题可能出在视差效应上。请帮帮我好吗?
代码如下:
<!DOCTYPE html>

text-align: justify;
text-justify: inter-word;
/* scroll-snap-align: start;*/
}
.parallax {
/* The image used */
background-image: url("IMG_7916_cut.jpg");
opacity: 0.8;
/* Full height */
height: 100%;
/* Create the parallax scrolling effect */

预先感谢您的帮助。
解决方法
是的,您可以将其更改为 div(注意我给了 div class="btn"
并在 css 上添加了 cursor: pointer
你可以在这里看到工作示例:
