HTML5 video error handling

Question

I need to tell, whether video cannot be played ("x" sign is shown in browser).

This code does't works. "onerror" event will never be fired under Firefox

var v = document.getElementsByTagName("video")[0];     if ( v != undefined )         v.onerror = function(e) {             if ( v.networkState == v.NETWORK_NO_SOURCE )             {                 // handle error             }         } 

What's wrong here ?

Answer 1

"onerror" is not a valid event type for <video>

Use "error" instead.

document.getElementsByTagName('video')[0].addEventListener('error', function(event) { ... }, true);
