WalkthroughThis update renames the project title in the README from "[Project Name]" to "DestINo" and introduces a new feature: an AI Travel Itinerary Planner. A new index.html file provides the HTML structure and form for collecting travel details. The script.js file implements functions to validate inputs, generate an itinerary based on destination data, and export the itinerary as a PDF using jsPDF. A complementary styles.css file defines the visual styling for the planner's interface. The underlying project structure remains intact, with additions focused on supporting the itinerary planning functionality. Changes

🧹 Nitpick comments (3)
script.js (1)
101-108: Enhance PDF export functionality.The current implementation has several limitations:
- No error handling for missing jsPDF
- Basic text formatting
- No handling of content overflow
Consider these improvements:
function exportItinerary() { + if (typeof window.jspdf === 'undefined') { + alert('PDF generation library not loaded. Please try again later.'); + return; + } + const { jsPDF } = window.jspdf; const doc = new jsPDF(); const itineraryContent = document.getElementById('itinerary-summary').innerText; - doc.text(itineraryContent, 10, 10); + + // Set font size and line height + doc.setFontSize(12); + const lineHeight = 7; + + // Split text into lines that fit the page width + const lines = doc.splitTextToSize(itineraryContent, 180); + + // Add multiple pages if content overflows + let y = 20; + lines.forEach(line => { + if (y > 280) { + doc.addPage(); + y = 20; + } + doc.text(line, 15, y); + y += lineHeight; + }); + doc.save('itinerary.pdf'); }index.html (1)
31-35: Add date input validation and loading state.The date inputs and generate button need improvements:
- Missing min/max date validation
- Missing loading state indicator
Apply these improvements:
<h2>Select Your Trip Dates</h2> - <input type="date" id="start-date"> - <input type="date" id="end-date"> + <input + type="date" + id="start-date" + aria-label="Select start date" + min="2024-02-14" + required + > + <input + type="date" + id="end-date" + aria-label="Select end date" + min="2024-02-14" + required + > - <button onclick="generateItinerary()">Generate Itinerary</button> + <button + onclick="generateItinerary()" + id="generate-btn" + aria-label="Generate travel itinerary" + > + <span class="btn-text">Generate Itinerary</span> + <span class="loading-spinner hidden"></span> + </button>styles.css (1)
1-102: Enhance styles for better UX and accessibility.The CSS needs improvements in several areas:
- Responsive design
- Loading states
- Focus states
- Print styles
Add these styles:
+/* Responsive design */ +@media (max-width: 768px) { + .form-container { + margin: 10px; + padding: 15px; + } + + input[type="text"], + input[type="number"] { + font-size: 16px; /* Prevent zoom on iOS */ + } +} +/* Loading spinner */ +.loading-spinner { + display: inline-block; + width: 20px; + height: 20px; + border: 2px solid #ffffff; + border-radius: 50%; + border-top-color: transparent; + animation: spin 1s linear infinite; +} + +@keyframes spin { + to { transform: rotate(360deg); } +} + +.hidden { + display: none; +} +/* Focus states */ +button:focus, +input:focus, +select:focus { + outline: 2px solid #4CAF50; + outline-offset: 2px; +} +/* Print styles */ +@media print { + .form-container, + button { + display: none; + } + + #itinerary-view { + box-shadow: none; + margin: 0; + padding: 0; + } +}

🛠️ Refactor suggestion
Improve input validation and error handling.
The function needs additional validation and error handling:
- Validate that end date is after start date
- Improve budget filtering logic
- Handle edge cases (e.g., no activities/accommodations within budget)
Apply these improvements:
function generateItinerary() {
const destinationSelect = document.getElementById('destination');
const selectedDestination = destinationSelect.value;
const budget = parseFloat(document.getElementById('budget').value);
const startDate = document.getElementById('start-date').value;
const endDate = document.getElementById('end-date').value;
if (!selectedDestination || isNaN(budget) || budget <= 0 || !startDate || !endDate) {
alert("Please select a valid destination, enter a valid budget, and select trip dates.");
return;
}
+ const start = new Date(startDate);
+ const end = new Date(endDate);
+ if (end <= start) {
+ alert("End date must be after start date.");
+ return;
+ }
+
const data = destinationData[selectedDestination];
if (!data) {
alert("Sorry, we don't have data for this destination.");
return;
}
- const start = new Date(startDate);
- const end = new Date(endDate);
const days = Math.floor((end - start) / (1000 * 60 * 60 * 24));
- let activities = data.activities.filter(activity => activity.cost <= budget);
- let accommodations = data.accommodations.filter(acc => acc.costPerNight <= budget / 3);
+ // Reserve 60% of budget for accommodation
+ const accommodationBudget = budget * 0.6;
+ const activityBudget = budget * 0.4;
+
+ let accommodations = data.accommodations.filter(acc => acc.costPerNight * days <= accommodationBudget);
+ let activities = data.activities.filter(activity => activity.cost <= activityBudget);
+
+ if (accommodations.length === 0 || activities.length === 0) {
+ alert("Sorry, no activities or accommodations available within your budget.");
+ return;

🛠️ Refactor suggestion
Enhance form accessibility and validation.
The form inputs need accessibility improvements and better validation:
- Missing ARIA labels
- Missing form validation attributes
- Missing currency indicator
Apply these improvements:
- <select id="destination">
+ <select id="destination" aria-label="Select your travel destination" required>
<option value="" disabled selected>Select a destination</option>
<option value="Paris">Paris</option>
<!-- ... other options ... -->
</select>
<h2>Enter Your Budget</h2>
- <input type="number" id="budget" placeholder="Enter Budget">
+ <div class="input-group">
+ <span class="currency">$</span>
+ <input

+ id="budget"
+ placeholder="Enter Budget"
+ aria-label="Enter your budget in USD"
+ min="0"
