Code Walkthrough: Countdown Timer with PDF Download
Your download will start in 30 seconds.
Let’s go step-by-step through the code implementation.
HTML: Structure the Countdown and Download Button
First, add the following HTML to your website. This will create a container for the countdown timer and a button to trigger the PDF download:
<div id="pdf-download-container">
<p id="countdown-text">Your download will start in <span id="countdown">20</span> seconds.</p>
<button id="pdf-download-btn" disabled>Download PDF</button>
</div>
- The
#pdf-download-container
div holds everything. - Inside, you have a paragraph displaying the countdown text with an ID of
countdown-text
, and aspan
to show the remaining time. - The
Download PDF
button is initially disabled until the countdown reaches zero.
JavaScript: Countdown Timer Logic and PDF Download Action
Here’s the core logic for the countdown timer and the download functionality:
// Countdown timer
let countdownTime = 25;
const countdownElement = document.getElementById('countdown');
const downloadButton = document.getElementById('pdf-download-btn');
const interval = setInterval(() => {
countdownTime--;
countdownElement.textContent = countdownTime;
if (countdownTime <= 0) {
clearInterval(interval);
countdownElement.textContent = "0";
downloadButton.disabled = false;
downloadButton.textContent = "Click to Download PDF";
}
}, 1000);
// Add PDF download functionality
downloadButton.addEventListener('click', () => {
window.location.href = "https://eleobo.com/wp-content/uploads/2025/01/Rain-Detector-Alarm-Project.pdf"; // Replace with your PDF URL
});
Step-by-Step Breakdown:
- Countdown Timer Setup: The
let countdownTime = 25;
sets the countdown duration in seconds. We usesetInterval()
to update the countdown every second until it reaches zero. - Enabling the Button: When the countdown reaches zero, we stop the timer and enable the download button by setting
downloadButton.disabled = false;
and changing its text to “Click to Download PDF.” - Download Action: The
addEventListener('click')
triggers the download by redirecting to a PDF URL. Replace the URL with the link to your specific PDF.
CSS: Style the Countdown and Download Button
Now, let’s style the countdown and the button to ensure they look polished and professional:
#pdf-download-container {
text-align: center;
margin: 20px;
font-family: Arial, sans-serif;
}
#pdf-download-btn {
background-color: #4CAF50;
color: white;
padding: 10px 20px;
font-size: 16px;
border: none;
border-radius: 5px;
cursor: not-allowed;
opacity: 0.6;
transition: opacity 0.3s, cursor 0.3s;
}
#pdf-download-btn:enabled {
cursor: pointer;
opacity: 1;
}
#countdown-text {
font-size: 18px;
margin-bottom: 10px;
}
Step-by-Step Breakdown of the CSS:
- The
#pdf-download-container
centers everything on the page and gives a clean, simple margin around it. - The
#pdf-download-btn
styles the button. Initially, the button has a reduced opacity and a “not-allowed” cursor to indicate it’s disabled. Once enabled, the opacity changes, and the cursor becomes clickable. - The
#countdown-text
styles the countdown message to make it more readable.
Customizing the Code: Changing the Countdown Timer and User Links
1. Changing the Countdown Timer Duration
- To adjust the countdown time, change the value of
let countdownTime = 25;
in the JavaScript code. - For example, if you want a 10-second countdown, change it to
let countdownTime = 10;
.
2. Changing the PDF Download Link
- To modify the PDF link, replace the URL in this line:
window.location.href = "https://eleobo.com/wp-content/uploads/2025/01/Rain-Detector-Alarm-Project.pdf"; // Replace with your PDF URL
- Make sure to paste your specific PDF URL here, so the correct file is downloaded.
Best Practices for a Seamless User Experience
- Test Different Countdown Durations: Depending on the content you’re offering, you may want to test different countdown times to see what resonates with your audience. Too long might cause frustration; too short might not build enough anticipation.
- Make the Button Stand Out: Customize the button’s color and size to ensure it stands out on your page. You want users to know exactly what they need to do to get their PDF.
- Ensure Accessibility: Make sure your countdown and download button are accessible to users with disabilities. Consider adding keyboard navigation and proper ARIA labels.
