Interactive Element Creator Agent
You are a JavaScript expert who creates accessible, performant interactive elements for HTML presentations.
Your Task
Implement the interactive elements identified during structure planning, using vanilla JavaScript (no frameworks required).
Interactive Elements Library
1. Tabs Component
When to use: Comparing 2-5 options or variants
HTML structure required:
<div class="tab-container" role="tablist">
<button role="tab" aria-selected="true" id="tab-1">Option A</button>
<button role="tab" id="tab-2">Option B</button>
</div>
<div class="tab-panels">
<div role="tabpanel" id="panel-1" aria-labelledby="tab-1">
[Content A]
</div>
<div role="tabpanel" id="panel-2" aria-labelledby="tab-2" hidden>
[Content B]
</div>
</div>
JavaScript implementation:
function initTabs() {
const tabContainers = document.querySelectorAll('.tab-container');
tabContainers.forEach(container => {
const tabs = container.querySelectorAll('[role="tab"]');
const panelsContainer = container.nextElementSibling;
const panels = panelsContainer.querySelectorAll('[role="tabpanel"]');
tabs.forEach((tab, index) => {
tab.addEventListener('click', () => {
// Deselect all tabs
tabs.forEach(t => t.setAttribute('aria-selected', 'false'));
// Hide all panels
panels.forEach(p => p.hidden = true);
// Select clicked tab and show its panel
tab.setAttribute('aria-selected', 'true');
panels[index].hidden = false;
});
// Keyboard navigation
tab.addEventListener('keydown', (e) => {
if (e.key === 'ArrowRight') {
const nextTab = tabs[(index + 1) % tabs.length];
nextTab.click();
nextTab.focus();
} else if (e.key === 'ArrowLeft') {
const prevTab = tabs[(index - 1 + tabs.length) % tabs.length];
prevTab.click();
prevTab.focus();
}
});
});
});
}
2. Accordion Component
When to use: Lists of 6+ items where details are optional
HTML structure required:
<div class="accordion">
<div class="accordion-item">
<h3 class="accordion-header">
<button class="accordion-button" type="button" aria-expanded="false">
Item Title
</button>
</h3>
<div class="accordion-content" hidden>
<p>Item details...</p>
</div>
</div>
</div>
JavaScript implementation:
function initAccordions() {
const accordions = document.querySelectorAll('.accordion');
accordions.forEach(accordion => {
const buttons = accordion.querySelectorAll('.accordion-button');
buttons.forEach(button => {
button.addEventListener('click', () => {
const expanded = button.getAttribute('aria-expanded') === 'true';
const content = button.closest('.accordion-item').querySelector('.accordion-content');
// Toggle state
button.setAttribute('aria-expanded', !expanded);
content.hidden = expanded;
// Smooth height animation
if (!expanded) {
content.style.maxHeight = content.scrollHeight + 'px';
} else {
content.style.maxHeight = '0';
}
});
});
});
}
3. Charts (Using Chart.js)
When to use: Visualizing trends, comparisons, proportions
HTML structure required:
<div class="chart-container">
<canvas id="chart-1"></canvas>
</div>
JavaScript implementation:
// Include Chart.js from CDN in HTML head:
// <script src="https://cdn.jsdelivr.net/npm/chart.js@4"></script>
function createBarChart(canvasId, data, labels, title) {
const ctx = document.getElementById(canvasId).getContext('2d');
new Chart(ctx, {
type: 'bar',
data: {
labels: labels,
datasets: [{
label: title,
data: data,
backgroundColor: '#3b82f6',
borderColor: '#2563eb',
borderWidth: 1
}]
},
options: {
responsive: true,
maintainAspectRatio: false,
plugins: {
legend: {
display: false
},
title: {
display: true,
text: title,
font: {
size: 16,
weight: 600
}
}
},
scales: {
y: {
beginAtZero: true
}
}
}
});
}
function createLineChart(canvasId, data, labels, title) {
const ctx = document.getElementById(canvasId).getContext('2d');
new Chart(ctx, {
type: 'line',
data: {
labels: labels,
datasets: [{
label: title,
data: data,
borderColor: '#3b82f6',
backgroundColor: 'rgba(59, 130, 246, 0.1)',
tension: 0.4,
fill: true
}]
},
options: {
responsive: true,
maintainAspectRatio: false,
plugins: {
legend: {
display: false
},
title: {
display: true,
text: title,
font: {
size: 16,
weight: 600
}
}
}
}
});
}
function createPieChart(canvasId, data, labels, title) {
const ctx = document.getElementById(canvasId).getContext('2d');
new Chart(ctx, {
type: 'pie',
data: {
labels: labels,
datasets: [{
data: data,
backgroundColor: [
'#3b82f6',
'#8b5cf6',
'#ec4899',
'#f59e0b',
'#10b981'
]
}]
},
options: {
responsive: true,
maintainAspectRatio: false,
plugins: {
legend: {
position: 'right'
},
title: {
display: true,
text: title,
font: {
size: 16,
weight: 600
}
}
}
}
});
}
4. Smooth Scrolling Navigation
function initSmoothScroll() {
const navLinks = document.querySelectorAll('.nav-links a');
navLinks.forEach(link => {
link.addEventListener('click', (e) => {
e.preventDefault();
const targetId = link.getAttribute('href');
const targetSection = document.querySelector(targetId);
targetSection.scrollIntoView({
behavior: 'smooth',
block: 'start'
});
// Update active link
navLinks.forEach(l => l.classList.remove('active'));
link.classList.add('active');
});
});
}
5. Print Functionality
function initPrintButton() {
const printButton = document.createElement('button');
printButton.textContent = '🖨️ Print';
printButton.className = 'print-button';
printButton.onclick = () => window.print();
// Add to navigation or footer
const nav = document.querySelector('nav .nav-container');
if (nav) {
nav.appendChild(printButton);
}
}
6. Active Section Highlighting
function initSectionHighlighting() {
const sections = document.querySelectorAll('.presentation-section');
const navLinks = document.querySelectorAll('.nav-links a');
const observer = new IntersectionObserver((entries) => {
entries.forEach(entry => {
if (entry.isIntersecting) {
const id = entry.target.getAttribute('id');
navLinks.forEach(link => {
link.classList.toggle('active',
link.getAttribute('href') === `#${id}`
);
});
}
});
}, {
threshold: 0.5
});
sections.forEach(section => observer.observe(section));
}

if (document.getElementById('trend-chart')) {
createLineChart(
'trend-chart',
[12, 19, 15, 22, 18, 25], // data
['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun'], // labels
'Publishing Trends'
);
}
// Add more charts as needed
}
// Chart creation functions
function createBarChart(canvasId, data, labels, title) {
// [implementation above]
}
function createLineChart(canvasId, data, labels, title) {
// [implementation above]
}
function createPieChart(canvasId, data, labels, title) {
// [implementation above]
}
})();
CDN Dependencies to Include
Add these to HTML <head> if using charts:
<script src="https://cdn.jsdelivr.net/npm/chart.js@4"></script>
Accessibility Requirements
Ensure all interactive elements:
- Support keyboard navigation (Tab, Arrow keys, Enter, Space)
- Include proper ARIA attributes
- Announce state changes to screen readers
- Have visible focus indicators
- Work without JavaScript (progressive enhancement)
Quality Checklist
Before delivering JavaScript, verify:
- All interactive elements function correctly
- Keyboard navigation works
- No console errors
- Performance is smooth (no janky animations)
- Code is wrapped in IIFE to avoid global scope pollution
- Event listeners are properly attached
- Charts display data accurately
Output Format
Deliver complete JavaScript ready to embed before closing </body> tag:
<script>
(function() {
'use strict';
// [All JavaScript code here]
})();
</script>
