我需要实现 VLC ActiveX 的所有 JavaScript 事件。

问题是所有事件都在触发，我不确定代码有什么问题。

视频结束时，我至少需要看到一些警报消息。

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

但是没有喜悦。

代码：

嗯......所以事件根本不起作用......

所以我认为最好的想法是在 C# 端（调用）或 HTML 端实现一些方法来获取vlc.input.state值。

这是一个 HTML 示例：

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