怎么样实现从地址栏获取参数作为视频地址自动播放？
程序代码：<script type="text/javascript" src="images/swfobject.js"></script>
<div class="video" id="CuPlayer"></div>
<script type="text/javascript">
var so = new SWFObject("CuPlayerMiniV4.swf","CuPlayerV4","600","410","9","#000000");
so.addParam("allowfullscreen","true");
so.addParam("allowscriptaccess","always");
so.addParam("wmode","opaque");
so.addParam("quality","high");
so.addParam("salign","lt");
so.addVariable("CuPlayerSetFile","CuPlayerSetFile.xml");
so.addVariable("CuPlayerWidth","600");
so.addVariable("CuPlayerHeight","410");
so.addVariable("CuPlayerAutoPlay","yes");
so.addVariable("CuPlayerImage","images/start.jpg");
so.addVariable("CuPlayerLogo","images/logo.png");
so.addVariable("CuPlayerPosition","bottom-right");
so.addVariable("CuPlayerFile","http://www.); //★★此处为视频播放地址URL
so.write("CuPlayer");
</script>我的网页播放代码如上，但我想将所有的视频播放地址由一个播放页即可任意播放了，减少网站体积！具体意思是：将视频播放地址由JS自动从地址栏获取参数，即地址栏地址如http://www.，打开这个页面，就想实现这播放器代码会直接获取后面参数作为视频地址播放！以后只要更改地址栏参数？后面的红色部分网址如http://www.即会自动换成pppp.fly视频进行播放。
请问有人可以解决这个问题吗？
另外如果找不到这个视频即提示视频已下架，谢谢
