}

js 一直跑 该环境属于iframe环境

var is_login_validity_msg = null;

xadmin.admin_login = setInterval(function(){

$.post("is_login_validity",{token:"token_@$%!"},function(res){

if (res.status === false)

{

if (!parent.is_login_validity_msg)

{

parent.is_login_validity_msg = res.info;

}

res.info = parent.is_login_validity_msg ? parent.is_login_validity_msg : res.info;

clearInterval(xadmin.admin_login);

layer.msg(res.info, {icon: 5, time: 1000*60*2}, function()

{

parent.location.reload();

window.location.href = res.url;

});

}

},'json');

},3000);
