我不知道我能多好地解释我的问题，所以我制作了两个 html 文件并尝试使用这些文件解释我的问题。
我在我的主页中使用 jquery(我从 web 获取的代码)滚动到 div 元素。因此，当用户单击链接时，它将向下滚动到主页中的特定元素。问题是当用户离开主页并转到其他网页时，这些链接就会失效并且无法使用。

在此示例网页中，它有 10 个菜单 (container1-10)。在这 10 个菜单中，其中 9 个(容器 1-9)只能在 index.html 中使用。容器 10 菜单链接到另一个页面 lol.html。
问题是当用户在 lol.html 中时，如果用户单击容器 1-9 中的任何菜单，则没有任何反应。我想在单击容器 1-9 时将用户重定向到该元素的主页。
希望我没有让任何人感到困惑
最佳答案
首先，在非主页的页面中编辑您的 A 标签:
<li><a href="/homePage.html/#con1">Container 1</a></li>
然后，您可以使用类似这样的东西来检测来自您主页中另一个页面的点击:
//Used for the demo, just get the window's location
var simulatedURL = "www.domaine.org/#case4";
var getAnchor = simulatedURL.split("#");
$('a[href="#' + getAnchor[1] + '"]').trigger("click");
请参阅quick Fiddle
关于javascript - 如果滚动到 div 不存在，则重定向到主页，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32649161/
