javascript - 根据url激活左侧栏的菜单

Question

我有两个不同的页面，它们有一个共同的侧边栏菜单。当我单击菜单时，它将重定向到另一个页面，并且应将一个类添加到父菜单。即使我刷新页面。

Check this code

这是我的 js 代码:

$(document).ready(function () {
     $("#sidebar-menu a").each(function () {
         var pageUrl = window.location.href.split(/[?#]/)[0];

         console.log(pageUrl);

         if (this.href == pageUrl) {
             $(this).addClass("active");
             $(this).parent().addClass("active"); // add active to li of the current link
             $(this).parent().parent().prev().addClass("active"); // add active class to an anchor
             $(this).parent().parent().parent().parent().prev().click();
             $(this).parent().parent().prev().click(); // click the item to make it drop
         }
    });
});

Actually, You give me only html and js code so I used the local storage for this solution. you can solve this problem using many way.
