Handle inject keypress event inside jQuery UI autocomplete

Is there a way to handle the event when the enter key is pressed in jquery's autocomplete function? If I click on the dropdown item I go to the next url

window.location.href = '/user?userId=' + ui.item.userId;

      

        
        
        
      

    

And it works great in the function selection section. But what if I need to change my url when I have typed a few letters and the dropdown results are shown, but I do not click on one of the items, instead I just press enter, how can I process it?

$('#search').autocomplete({
    source: function(request, response) {
        $.ajax({
            url: "/search/users",
            data: {
                query: request.term
            },
            success: function(data) {
                var transformed = $.map(data, function(el) {
                    return {
                        name: el.name,
                        email: el.email
                    };
                });
                response(transformed);
            },
            error: function() {
                response([]);
            }
        });
    },
    select: function(event, ui) {
        window.location.href = '/user?userId=' + ui.item.userId;
    }
}).data("ui-autocomplete")._renderItem = function(ul, item) {
    var $a = $("<a></a>").append(item.name);
    highlightText(this.term, $a);
    return $("<li></li>").append($a).appendTo(ul);
};

      

        
        
        
      

    

I tried with this but I am wondering if there is a better solution

$('#search').on('keypress', function(e) {
    if (e.which == 13 && $(this).val()) {
        window.location.href = '/users/list?name=' + $(this).val();
    }
});
