我正在尝试创建一个从 AS3 中的 XML 播放列表中调用随机视频的函数,但不知道从哪里开始。我已经尝试了多种方法并且正在打破我的大脑。请停下来!
虽然我有一些运气拉视频,但随机化不起作用,我还需要从 xml 中获取标题。
<?xml version="1.0" encoding="UTF-8"?>
<playlist>
<video url="video/flvs/04-02-02-09-01.flv" title="angry" />
<video url="video/flvs/14-02-01-08-01.flv" title="happy" />
<video url="video/flvs/04-02-01-04-01.flv" title="sad" />
<video url="video/flvs/06-02-02-03-01.flv" title="frustrated" />
<video url="video/flvs/21-02-02-08-01.flv" title="no emotion" />
</playlist>
AS3:
function Init():void{
_urlRequest = new URLRequest("playlist.xml");
_xmlLoader = new URLLoader();
_xmlLoader = new URLLoader(_urlRequest);
_xmlLoader.addEventListener(Event.COMPLETE, XMLLoaded, false, 0, true);
}
function XMLLoaded($e:Event):void {
_xml = new XML($e.target.data);
var randomVideo:XML = _xml.video[Math.floor(_xml.video.length() * Math.random())];
PlayVideo();
}
