我正在尝试创建一个从AS3中的XML播放列表调用随机视频的功能,并且不知道从哪里开始。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动视频,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();
}

您可以像这样访问随机播放列表节点(假设您的XML由名为“xml”的变量引用):
var randomVideo:XML = xml.video[Math.floor(xml.video.length() * Math.random())];
您可以访问以下属性:
var randomURL:String = randomVideo.@url;
var randomTitle:String = randomVideo.@title;
