onerror Event

Definition and Usage The onerror event is triggered if an error occurs while loading an external file (e.g. a document or an image).

Tip: When used on audio/video media, related events that occurs when there is some kind of disturbance to the media loading process, are:

• onabort
• onemptied
• onstalled
• onsuspend

In HTML:

element onerror="myScript">

In JavaScript, using the addEventListener() method:

object.addEventListener("error", myScript);

Note: The addEventListener() method is not supported in Internet Explorer 8 and earlier versions.

Example Execute a JavaScript if an error occurs when loading an image:

img src="image.gif" onerror="myFunction()">

onerror Event

*Update August 2017: onerror is fired by Chrome and Firefox. onload is fired by Internet Explorer. Edge fires neither onerror nor onload. I wouldnt use this method but it could work in some cases. See also
