我非常需要一些帮助，因为我的导航栏存在一些问题。我的其中一个按钮是下拉菜单，但我的下拉内容卡在导航栏内，我希望它下降到正下方。具有相同代码的不同HTML页面看起来完全不同
var myIndex = 0;
carousel();
function carousel() {
var i;
var x = document.getElementsByClassName("mySlides");
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
myIndex++;
if (myIndex > x.length) {
myIndex = 1
}
x[myIndex - 1].style.display = "block";
setTimeout(carousel, 4000); // Change image every 2 seconds

我认为你需要澄清你的问题实际上是什么。 – Carcigenicate
