$("#i_video").hide();
}
else if (video.substr(0, 7).toLowerCase() == "http://") {
//是flash http地址
$("#i_video").html("<embed src=\"" + video + "\" quality=\"high\" width=\"480\" height=\"400\" align=\"middle\" allowScriptAccess=\"always\" allowFullScreen=\"true\" mode=\"transparent\" type=\"application/x-shockwave-flash\"></embed>");
}
