我的菜单可以包含很多部分（由于整页内容很长），所以我的菜单上有一个 X 滚动条。
当 scrollspy 突出显示它时，我如何在正确的菜单条目上自动滚动。
例如，如果您滚动到第 18/19 部分，我们将看不到菜单中突出显示的项目
最后，首先我更改了 bootstrap.js 的代码以在 css "activation" 之后添加一个 scrollIntoView 操作。但这不是做事的正确方法。
在我发现 bootstrap events
然后我在我的所有菜单元素上使用了一个 jquery 选择器，scrollspy 激活并在这个元素上滚动：
$(document).ready(function () {
console.log("ready!");
$('.navbar-nav li').on('activate.bs.scrollspy', function (e) {
e.target.scrollIntoView();
}
);
});
body {
position: relative;
scroll-behavior: smooth;
}

我的菜单可以包含很多部分（由于整页内容很长），所以我的菜单上有一个 X 滚动条。
当 scrollspy 突出显示它时，我如何在正确的菜单条目上自动滚动。
例如，如果您滚动到第 18/19 部分，我们将看不到菜单中突出显示的项目
最后，首先我更改了 bootstrap.js 的代码以在 css "activation" 之后添加一个 scrollIntoView 操作。但这不是做事的正确方法。 在我发现 bootstrap events
然后我在我的所有菜单元素上使用了一个 jquery 选择器，scrollspy 激活并在这个元素上滚动：
$(document).ready(function () {
console.log("ready!");
$('.navbar-nav li').on('activate.bs.scrollspy', function (e) {
e.target.scrollIntoView();
}
);
});
body {
position: relative;
scroll-behavior: smooth;
