HTML5 视频错误处理 [英] HTML5 video error handling

问题描述

我需要告诉，视频是否无法播放(浏览器中显示x"符号).

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

此代码不起作用.在 Firefox 下永远不会触发onerror"事件

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
            }
        }

这里有什么问题?

"onerror" is not a valid event type for

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

改用错误".

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