Why Breadcrumbs Matter?

Breadcrumbs improve the user experience by.

  • Offering quick navigation to previous pages or sections.
  • Helping users understand the site hierarchy.
  • Enhancing SEO by adding structured navigation links.

How to Build Dynamic Breadcrumbs?

1. The HTML Framework

<!DOCTYPE HTML>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Dynamic Breadcrumbs</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.6.0/css/all.min.css">
</head>
<body>
    <div class="syllabus"></div>
</body>
</html>

2. Adding Some Style

<style>
    .syllabus a {
        font-size: 20px;
        font-family: auto;
        font-weight: 100;
        font-style: normal;
        text-decoration: none;
    }
</style>

3. The jQuery Script

<script type="text/javascript">
    $(document).ready(function () {
        var breadcrupbsCollection = $(location).attr('href').split('/');
        var url = '';
        var $html = '';
        
        for (let index = 3; index < breadcrupbsCollection.length; index++) {
            url += '/' + breadcrupbsCollection[index];
            
            if (index == breadcrupbsCollection.length - 1) {
                $html += '<a href="' + url + '">' + decodeURIComponent(breadcrupbsCollection[index]) + '</a>';
            } else {
                $html += '<a href="' + url + '">' + decodeURIComponent(breadcrupbsCollection[index]).replaceAll("%20", " ") + '</a> > ';
            }
        }
        
        $('.syllabus').html($html);
    });
</script>
