我通过AJAX把下面的拼接的字符串返回，可是为什么这段播放flash的代码不播放嗯，如果直接写在页面上就可以，请高手指点，谢谢，代码如下：
StringBuilder sb = new StringBuilder();
sb.Append("<p id=\"player1\">");
sb.Append("<a href=http://topic.csdn.net/u/20100816/18//"http://www.macromedia.com/go/getflashplayer/"></a>");
sb.Append("</p>");
sb.Append("<script type=\"text/javascript\"> var s1 = new SWFObject(\"flvplayer.swf\",\"single\",\"414\",\"337\",\"7\");");
sb.Append("s1.addParam(\"allowfullscreen\",\"true\"); s1.addVariable(\"file\",\"Video/" + videopath);
sb.Append("\");s1.addVariable(\"image\",\"Upfile/" + imgpath);
sb.Append("\");s1.addVariable(\"width\",\"414\"); s1.addVariable(\"height\",\"337\");s1.addVariable(\"showdigits\",\"total\");s1.write(\"player1\");</script>");
