Navigating to Another Page by Clicking a Button Using Basic JavaScript
Navigating to a different page when a button is clicked is a common task in web development. Using JavaScript, this can be accomplished easily and effectively. This blog post will guide you through the process step-by-step, ensuring you understand the fundamentals of JavaScript and its interaction with HTML elements.

Step 1: Setting Up the HTML Structure
First, create a simple HTML file with a button element. This button will be used to trigger the navigation to another page.
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Navigate to Another Page</title>
</head>
<body>
<button id="navigateButton">Go to Page</button>
<script src="script.js"></script>
</body>
</html>
In this HTML structure:
- We have a button element with the ID
navigateButton. - We include an external JavaScript file named
script.jswhere our navigation logic will be implemented.
Step 2: Writing the JavaScript Code
Next, we need to write the JavaScript code to handle the button click event and navigate to another page.
JavaScript (script.js)
Create a new file named script.js and add the following code:
document.addEventListener('DOMContentLoaded', function() {
var button = document.getElementById('navigateButton');
button.addEventListener('click', function() {
window.location.href = 'https://www.example.com';
});
});

In this JavaScript code:
- We wait for the DOM to fully load using
DOMContentLoaded. - We select the button element using
document.getElementById. - We add a click event listener to the button that changes the
window.location.hrefproperty to the URL of the page we want to navigate to.
Explanation
document.addEventListener('DOMContentLoaded', function() {...});: This ensures that the JavaScript code runs only after the HTML document has been fully loaded and parsed.var button = document.getElementById('navigateButton');: This retrieves the button element from the DOM.button.addEventListener('click', function() {...});: This adds a click event listener to the button.window.location.href = 'https://www.example.com';: This line sets thehrefproperty ofwindow.locationto the desired URL, causing the browser to navigate to that URL.
Step 3: Testing the Navigation
To test the navigation functionality, follow these steps:
- Save the
index.htmlandscript.jsfiles. - Open
index.htmlin a web browser. - Click the “Go to Page” button.
You should see the browser navigate to the specified URL (https://www.example.com in this example).
Customizing the Navigation
You can customize the navigation URL based on your needs. For instance, you might want to navigate to a different page within your own website. Simply change the URL in the JavaScript code:
button.addEventListener('click', function() {
window.location.href = 'about.html';
});
This will navigate to about.html in the same directory as your current page.
Conclusion
Navigating to another page by clicking a button using basic JavaScript is a fundamental task in web development. By following the steps outlined in this blog post, you can easily implement this functionality in your own projects. Understanding how to interact with the DOM and handle events is crucial for creating dynamic and interactive web applications.
