绑定包含视频的对象元素的单击事件

Question

我正在附加一个对象元素。如何在IE中单击播放或暂停按钮时触发功能？

<object type="video/x-ms-wmv" data="test.wmv" width="340" height="280"  id="movie1">
  <param name="src" value="test.wmv" />
  <param name="controller" value="false" />
  <param name="autostart" value="true" />
</object>

我的js代码：

window.addEventListener('load', function () {
    document.getElementById("movie1").addEventListener("click", onMovieStateChange, false);
});

function onMovieStateChange() {
    var state = document.movie1.PlayState
    if (state == 0) {
        alert('video ended');
    }
    if (state == 1) {
        alert('video paused');
    }
    alert('hi');
}
