怎么设置Ajax请求成功即刻打开新窗口

jQuery.ajax({
"type":"post",
"url":"http://www.baidu.com", 
"success":function(rel){
if(rel.isSuccess){ 
window.open(rel.url,"_blank");
}
}
});

var result="";
jQuery.ajax({
"type":"post",
"url":"http://www.baidu.com", 
"success":function(rel){
if(rel.isSuccess){ 
result=rel.url;
//window.open(rel.url,"_blank");
}
}
});
if(result.length>0){
window.open(result,"_blank");
}

$(document).delegate("a", "click", function () { 
var actionUrl = $(this).attr("href"); 
var ssoAction = function () { window.open(actionUrl, '_blank'); }; 
if (isLogin()) { 
ssoAction(); 
} else { 
popup.show({login:function () { 
$.ajax({ 
type: "post", 
dataType: "json", 
url: "/Account/Login", 
data: $("frmLogin").serialize(), 
//发送方式改为同步，避免弹出页面被浏览器拦截
async: false, 
success: function (oData) { 
ssoAction(); 
} 
}); 
}); 
} 
return false; 
});
