Dynamically know the image file not found

[kavin clain]

In javascript I am loading an image tag using ImageObj.src = 'loadimg.do';.

It works fine. But if the image file not found this way, then I want to set a default image.

My question is how to know the action 'loadimg.do' could not find the requested image.

Best to handle that on the server.

It would be better to do it on the server as mentioned.

There is a way to use

<img   onerror="this.src='error.gif'" src="bad.gif" />

I am using myeclipse. When I typed onerror... it was showing warning.
Then I checked http://www.w3schools.com/tags/tag_IMG.asp .

No such attribute defined for img tag. Even though,
I am going to try this code... but I think there should be one such attribute.
I tried the server side code & It is perfectly working.

onerror is valid and it is not an attribute, it is a JavaScript event handler.

What your IDE says is of no concern. IDEs are notoriously bad at client-side development.
