Here is a way to display images using the img tag:
If 1.jpg exists, show 1.jpg.
If not, check for 2.jpg and display it if it exists.
If neither 1.jpg nor 2.jpg exist, display 3.jpg.
<img src="1.jpg" onerror="this.src='2.jpg'; this.onerror='this.src=3.jpg'" />
An error occurred when trying this code. Is there another way to achieve this functionality?
Separate the handler into a JavaScript function:
function handleImageError(img) {
img.onerror = function() {
img.src = 'fallback.jpg';
}
img.src = 'main.jpg;
}
<img src="image.jpg" onerror="handleImageError(this)" />
Utilize the above function to create multiple cascading onerror handlers if needed. For longer sequences, consider storing images in an array and using the handler to increment an index with each call.
