                        "css": {
                            "display": "none",
                            "position": "fixed",
                            "top": "0",

推荐答案

使用after_open 回调.选中此演示.

new PNotify({
   //....
    after_open: function (notify) {
        $(".btn-class", notify.container).focus();
    }
   //....
});
