How to Handle Image Loading Errors with the onerror Attribute in All Browsers?

Handle Image Loading Errors with the onerror Attribute

Incorporating images into web applications often requires handling potential loading failures. The onerror attribute provides a convenient solution for gracefully handling such errors.

Background

As described in the given HTML code, the onerror attribute sets an event listener that executes a script when an image's loading process encounters an error. However, as mentioned in the query, this approach may fail in certain browsers such as Chrome and Mozilla.

Solution

To ensure compatibility across browsers, consider using the following syntax:

<code class="html"><img  src="/static/imghwm/default1.png" data-src="invalid_link" class="lazy" onerror="this.onerror=null;this.;" alt="How to Handle Image Loading Errors with the onerror Attribute in All Browsers?" ></code>

This code provides an alternative fallback image if the primary image fails to load. To prevent an infinite loop if the backup URL is also invalid, the code nullifies the error handler using "this.onerror=null;".

Live Demonstration

An interactive demonstration of this solution is available at the following link:

Additional Considerations

As outlined in the solution, using this approach ensures compatibility in both Chrome and Mozilla. However, it's important to note that the handling of image loading errors may vary across different browser environments.
