Placeholder Image Tutorial

This page demonstrates how to use a placeholder image URL. These are useful during development to visualize where images will go before the final assets are ready.

Image Preview Area

You can typically generate these placeholder images using services like Placeholder.com, Lorem Picsum, or by creating simple image files yourself. The URL requested, /tutorials/placeholder-image-ajax.jpg, conceptually represents such an image.

In a real application, this would likely be an <img src="/tutorials/placeholder-image-ajax.jpg" alt="Descriptive text"> tag in your HTML, or dynamically set via JavaScript.

Example HTML:

<img src="/tutorials/placeholder-image-ajax.jpg" alt="Placeholder for article image">

Example JavaScript (AJAX fetch):

// Simulate fetching image data
const imageUrl = "/tutorials/placeholder-image-ajax.jpg";

fetch(imageUrl)
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok');
}
return response.blob();
})
.then(blob => {
const imgUrl = URL.createObjectURL(blob);
const imgElement = document.createElement('img');
imgElement.src = imgUrl;
imgElement.alt = "Dynamically loaded placeholder";
document.body.appendChild(imgElement); // Append to your desired location
URL.revokeObjectURL(imgUrl); // Clean up
})
.catch(error => {
console.error('There has been a problem with your fetch operation:', error);
});

While this specific request points to a .jpg file, the actual content served might be a small, low-resolution placeholder image or even a generated image on the fly depending on the server's implementation.
