Adjust the CSS of a nested div within the currently selected div upon page load

I am facing an issue with a page that users access by clicking through an ebook. Upon clicking a link, they are directed to a specific product on the page, and the URLs look like

example.com/#product1

example.com/#product6

example.com/#product15,

etc...

The page automatically scrolls to that section using this code snippet:

<script type="text/javascript">
jQuery(document).ready(function(){
     jQuery('html,body').animate({
          scrollTop: jQuery(window.location.hash).offset().top-150
      }, 900, 'swing');
});

There is another div within the #product1 div named #amazonbutton, which has a style of display:none.

<div id="product1" class="product">
  <a href="link">
    <div id="amazonbutton"><img src="amazonbuttonz" />
    </div>
  </a>
</div>

This button serves as a "go to Amazon" option but remains hidden for all items except the currently active div. Essentially, it should display only for the active div while staying hidden for all inactive ones.

How can I achieve this with jQuery?

I have some incomplete code that I'm struggling with:

jQuery(function() {
  jQuery('amazonbutton').each(function() {
    if (jQuery(this).attr('href')  ===  window.location.href) {
      jQuery(this).addClass('active');
    }
  });
});

Any help would be greatly appreciated!

Answer №1

Have you heard of the awesome feature known as document.activeElement? This read-only property keeps track of the currently active element.

$('.yourdivclass').hide();
$(document.activeElement).show();

To activate an element, you can use .focus() or .activate().

Answer №2

At first glance, I noticed that you were looping through the amazonbutton element in your code, but it wasn't a link. This means you can't check the attr href. It seems like you intended to check the href of the parent of the amazonbutton instead. Additionally, is amazonbutton in your loop a class or an id? Don't forget to add a . for a class or a # for an id. You could try the following code:

jQuery(function() {
  jQuery('#amazonbutton').each(function() {
    if (jQuery(this).parent().attr('href') === window.location.href) {
      jQuery(this).addClass('active');
    }
  });
});
