JavaScript error
 Yes Yes Almost Yes No

When the browser encounters a JavaScript error it does the following:

  • With traditional registration the browser fires an event with type undefined from the test link. (Except Safari, which fires it from an undefined node.)
  • With the other event registrations the browser fires an error event from the window.
Image source wrong

When an image file does not exist the error event should fire from the <img> node.
Script source wrong
 Not tested No Yes Incomplete Yes Yes No

When a script file does not exist the error event should fire from the <script> node.

  • In traditional registration Firefox fires an event with type undefined from the test link, and bubbles it up to document and window.
CSS source wrong
 Not tested Incomplete No No No No

When a CSS file does not exist the error event should fire from the <link> node.

  • IE fires the event the second and subsequent times, but not the first time.
iframe source wrong

When an HTML file loaded into an iframe does not exist the error event should fire from the <iframe> node. At least, that would make sense, wouldn’t it?
