在我最近工作的网站上实现自动完成功能时，我遇到了同样的问题。这是我想出的解决方案：

$("input").focusin(function () {
    $(document).keypress(function (e) {
        if (e.which == 13) {
            var firstResult = $(".pac-container .pac-item:first").text();

            var geocoder = new google.maps.Geocoder();
            geocoder.geocode({"address":firstResult }, function(results, status) {
                if (status == google.maps.GeocoderStatus.OK) {
                    var lat = results[0].geometry.location.lat(),
                        lng = results[0].geometry.location.lng(),
                        placeName = results[0].address_components[0].long_name,
                        latlng = new google.maps.LatLng(lat, lng);

                        $(".pac-container .pac-item:first").addClass("pac-selected");
                        $(".pac-container").css("display","none");
                        $("#searchTextField").val(firstResult);
                        $(".pac-container").css("visibility","hidden");

                    moveMarker(placeName, latlng);

                }
            });
        } else {
            $(".pac-container").css("visibility","visible");
        }

    });
});
