<!DOCTYPE html>
<html lang="en">
<head>
<title>Change image src on click JavaScript</title>
<style>
.responsive
{
width: 100%;    
}
</style>    
</head>             
<body> 
    
<img src="car.jpg" class="responsive" id='image'>
<button onclick="changeImage()">Change Image</button>    
    
    
<script src="script.js"></script>    
</body>

function changeImage()
{
    var img = document.getElementById('image');
    img.src = 'bike.jpg';
}
</script>

    img.setAttribute('src','bike.jpg'); 
}
</script>
