How to Maintain Menu and Page State After Page Reload Using Storage?

Maintaining Menu State after Page Reload

To preserve the state of the menu after a page reload, you can utilize local storage. Here's how:

1. Store Menu State: Use JavaScript's localStorage to store the current menu state, including the translated position of the clicked menu link.

<code class="javascript">// Assuming you have identified the clicked menu link as `clickedLink`
localStorage.setItem('menuState', clickedLink.id);</code>

2. Retrieve Menu State on Page Load: On subsequent page loads, retrieve the stored menu state from localStorage.

<code class="javascript">const menuState = localStorage.getItem('menuState');</code>

3. Restore Menu State: Restore the menu state by setting the translated position of the menu link specified in menuState.

<code class="javascript">if (menuState) {
  const clickedLink = document.getElementById(menuState);
  clickedLink.classList.add('clicked', 'hovered');
  // Adjust translation and other styles accordingly.
}</code>

4. Keep Page State: If you want to maintain the current page as well, you can store the page number in localStorage. Retrieve and restore it in a similar manner.

<code class="javascript">// Assuming you have a variable `currentPage` to store the current page
localStorage.setItem('pageState', currentPage);

const pageState = localStorage.getItem('pageState');
if (pageState) {
  currentPage = pageState;
  // Adjust page content and navigation state accordingly.
}</code>

5. Clear Menu State: If desired, you can clear the menu state by removing the localStorage variable. This could be done on logout or navigation to a different section of the website.

<code class="javascript">localStorage.removeItem('menuState');
localStorage.removeItem('pageState');</code>
