1、插入js在</head>之上（其中head_tongyong.css是调用的css）：
------------------------
<link rel="stylesheet" type="text/css" href="/templets/nvren/head_tongyong.css">
<script language="java script" type="text/java script"
src="{dede:global.cfg_cmsurl/}/include/dedeajax2.js"></script>
<script language="java script" type="text/java script">
<!--
function CheckLogin(){
var taget_obj = document.getElementById('_userlogin');
myajax = new DedeAjax(taget_obj,false,false,'','','');
myajax.SendGet2("{dede:global.cfg_cmspath/}/member/ajax_loginsta_lady.php");
DedeXHTTP = null;
}
-->
</script>
---------------------------------
