🎯 Events

The plugin triggers custom events on the container element:

$('#page')
    .on('verticalscroll:init', function(e, index, $section) {
        console.log('Initialized at section', index);
    })
    .on('verticalscroll:beforescroll', function(e, targetIndex, $targetSection, currentIndex) {
        // Return false to cancel scroll
        if (targetIndex === 2 && !userLoggedIn) {
            e.preventDefault();
            return false;
        }
    })
    .on('verticalscroll:afterscroll', function(e, index, $section, previousIndex) {
        console.log('Scrolled to section', index);
    })
    .on('verticalscroll:sectionchange', function(e, index, $section, previousIndex) {
        console.log('Active section changed to', index);
    })
    .on('verticalscroll:resize', function(e, isEnabled) {
        console.log('Plugin is', isEnabled ? 'enabled' : 'disabled');
    })
    .on('verticalscroll:destroy', function() {
        console.log('Plugin destroyed');
    });

♿ Accessibility

The plugin is built with accessibility in mind:

Keyboard Navigation: Full support for arrow keys, Page Up/Down, Home/End
ARIA Labels: Proper roles and labels for screen readers
Focus Management: Sections receive focus after navigation
Reduced Motion: Respects prefers-reduced-motion media query
High Contrast: Supports prefers-contrast media query

Section Labels

Use data-vs-label attribute to provide meaningful labels for screen readers and tooltips:

<section data-vs-label="About Our Company">
    <!-- content -->
</section>

📱 Responsive Design

The plugin automatically disables on mobile devices by default:

$('#page').verticalScroll({
    responsive: true,
    mobileBreakpoint: 768  // Disable below 768px
});

When disabled, the container becomes normally scrollable.

🔧 Advanced Usage

Promise-Based Navigation

All navigation methods return jQuery Deferred promises:

$('#page').verticalScroll('scrollToSection', 3)
    .done(function() {
        console.log('Navigation complete');
    })
    .fail(function(reason) {
        console.log('Navigation failed:', reason);
    });

Deep Linking

// On page load, scroll to hash section
$(document).ready(function() {
    $('#page').verticalScroll({
        onInit: function() {
            if (window.location.hash) {
                $('#page').verticalScroll('scrollToId', window.location.hash);
            }
        },
        onAfterScroll: function(index, $section) {
            // Update URL hash
            var id = $section.attr('id');
            if (id) {
                history.replaceState(null, null, '#' + id);
            }
        }
    });
});

Integration with Analytics

$('#page').verticalScroll({
    onSectionChange: function(index, $section) {
        // Track in Google Analytics
        gtag('event', 'section_view', {
            'section_index': index,
            'section_id': $section.attr('id')
        });
    }
});
