Styling from the existing list of elements is implemented on the new set of elements using JavaScript

I have 6 different applications represented by <div> elements. Each <div> contains a menu with child menus in the form of unordered lists, each containing an <img> and <p> tag.

To navigate between these elements, I've added a back button which will store the history of visited elements using unique IDs.

An array called pageHistory is used to keep track of all the elements visited:

var pageHistory = { "History": [] };

Whenever a <div>, menu, or child menu is clicked, it is added to the pageHistory array like this: pageHistory.History.push(menu);

While this functionality works correctly, there are some issues when navigating back from one <div> to another. The CSS styling for the child menu from the previous selection remains applied to the new selection, and the selected menu is not highlighted when clicking the back button.

The goal is to maintain the individual CSS styles for each element and ensure that the selected menu and child menu are highlighted properly when using the back button.

Answer №1

In the realm of modern web applications, it has become common practice to load data or update the document object model (DOM) through AJAX without the need to navigate away from the original page. This approach creates a seamless, desktop-like user experience. One effective technique involves utilizing the URL hash value, which offers several advantages such as reduced client-side bandwidth consumption, improved response time, and enhanced interactivity within the application. By simply adding a hash character to the URL, we can extract the subsequent string and use it as a parameter in AJAX requests. Implementing a listener event to monitor for changes in the URL hash enables us to trigger custom JavaScript functions.

To achieve this, make use of hash change events and employ JavaScript to apply your custom CSS styles dynamically.
