注意：此方法也适用与其他字段，做好自己的设置即可 1、在head中加入 script src= {dede:global.cfg_cmsurl/}/include/dedeajax2.js type = text/javascript /script script language= javascript function CheckLogin_c(){ var
1、在<head>中加入
<script src="{dede:global.cfg_cmsurl/}/include/dedeajax2.js"type="text/javascript" ></script>
<script language="javascript">
function CheckLogin_c(){
var taget_obj = document.getElementById('_userlogin_c');
var req = document.getElementById('hid').value;
myajax = new DedeAjax(taget_obj,false,fal se,'','','');
myajax.SendGet2("{dede:global.cfg_cmspath/}/member/ajax_loginsta_c.php?val="+req);
DedeXHTTP = null;
}
</script>
2、在模板中<span id="_userlogin_c">
购买链接（未登录时候显示）：{dede:field.url1/}<br />
市场价格（未登录时候显示）：{dede:field.jiage1/}<br />
</span>
<input type="hidden" value="{dede:field.aid/}" id="hid" />
<script language="javascript" type="text/javascript">CheckLogin_c();</script>
3、在member新建一个文件ajax_loginsta_c.php查看源码 打印代码帮助
