How to get last name from breadcrumbs?

Question

JavaScript

I want to implement the following:
1. There are breadcrumbs on several pages, in which the last entry is the page on which we are.
2. There is a field where I want to display the name of the same page
3. There is a jumi that can display php code on the page.
Essence of a question:
How to implement?
Breadcrumbs template code:

<ul itemscope itemtype="http://schema.org/BreadcrumbList" class="breadcrumb<?php echo $moduleclass_sfx; ?>">
  <?php if ($params->get('showHere', 1)) : ?>
    <li class="active">
      <?php echo JText::_('MOD_BREADCRUMBS_HERE'); ?>&#160;
    </li>
  <?php endif; ?>

  <?php
  // Get rid of duplicated entries on trail including home page when using multilanguage
  for ($i = 0; $i < $count; $i++)
  {
    if ($i == 1 && !empty($list[$i]->link) && !empty($list[$i - 1]->link) && $list[$i]->link == $list[$i - 1]->link)
    {
      unset($list[$i]);
    }
  }

  // Find last and penultimate items in breadcrumbs list
  end($list);
  $last_item_key = key($list);
  prev($list);
  $penult_item_key = key($list);

  // Make a link if not the last item in the breadcrumbs
  $show_last = $params->get('showLast', 1);

  // Generate the trail
  foreach ($list as $key => $item) :
    if ($key != $last_item_key) :
      // Render all but last item - along with separator ?>
      <li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem" class="breadcrumb-item">
        <?php if (!empty($item->link)) : ?>

            <span itemprop="name">

        <meta itemprop="position" content="<?php echo $key + 1; ?>">
      </li>
    <?php elseif ($show_last) :
      // Render last item if reqd. ?>
      <li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem" class="breadcrumb-item active">
        <span itemprop="name">
          <?php echo $item->name; ?>
        </span>
        <meta itemprop="position" content="<?php echo $key + 1; ?>">
      </li>
    <?php endif;
  endforeach; ?>
</ul>

Answer 1

1. having $window for some reason you keep using $(window)
2. you use $(elem) in isScrolledIntoView even though you pass $(this)
3. find(".svg path") - invalid selector
