$("#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>");
