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);
