Yes, you can change the src attribute of an image (<img>) using JavaScript. Here’s how you can do it:
Example:
#html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Change Image Source</title>
</head>
<body>
<img id="myImage" src="image1.jpg" alt="Image" width="300">
<button onclick="changeImage()">Change Image</button>
<script>
function changeImage() {
// Select the image element
const image = document.getElementById('myImage');
// Change the src attribute to a new image URL
image.src = 'image2.jpg';
}
</script>
</body>
</html>Review:
- HTML Structure:
- An
<img>element is given an initialsrcattribute (image1.jpg). - A button is used to trigger the JavaScript function that changes the image source.
- An
- JavaScript Function:
- The
changeImage()function is triggered when the button is clicked. - It selects the image using
document.getElementById()and changes thesrcattribute to a new image URL (image2.jpg).
- The
Dynamic Image URLs
If you need to change the image source dynamically (e.g., based on user input or some other condition), you can do that by passing the new URL into the function.
#javascript
<script>
function changeImage(newSrc) {
const image = document.getElementById('myImage');
image.src = newSrc;
}
</script>
<button onclick="changeImage('image3.jpg')">Change to Image 3</button>
<button onclick="changeImage('image4.jpg')">Change to Image 4</button>This method allows you to dynamically change the image based on different actions.
Reducing Bugs with Coding Filters in Complex Applications!
Coding filters can help reduce bugs by simplifying complex application logic. When developers use filters to isolate specific tasks, they decrease the likelihood of errors caused by unhandled conditions or improper data handling. This leads to more stable applications with fewer issues.
