如何测试VLC ActiveX的事件

我需要实现VLC ActiveX的所有JavaScript事件。如何测试VLC ActiveX的事件

问题是，所有事件都是触发的，我不确定代码中出了什么问题。

当视频结束时，我至少需要看到一些警告消息。

正是在这里>>>registerVLCEvent('MediaPlayerEndReached', handleEvents);

但没有喜悦。

代码：

当然，当你调用registerVLCEvent存在VLC对象？你似乎没有在等待页面加载 – 2013-02-13 15:43:35

嗯......这样的事件不工作...

因此，我认为最好的办法是TI实现在C＃侧一些方法（调用）或在HTML端获取vlc.input.state值。

下面是HTML的例子：

$(document).ready(function() { 
      start_timer = setInterval(function() { 
       var vlc = getVLC("vlc2"); 
       var s = vlc.input.state; 
       // alert(s); 
      }, 
     1000); 
     });

你能详细说明这是如何工作的吗？ – ElHaix 2013-08-26 23:47:53
