如何保持Google地图的缩放级别？

Question

I have a asp website and it contains a street address field which will auto complete from Google maps.Near the textbox field there is a image button.A pop up window will show google maps with marker of the place in street address field when we click the button.Currently my zoom level is 15.The user may zoom in the map and close the window.Then he may return back to map again.Currently the zoom level will return to 15 again.How can i keep the zoom level selected by user?

OnClientClick of imagebutton.

             function SetStreet() {
                    $('#map-canvas').fadeIn('slow', function() {
                        google.maps.event.trigger(map, 'resize');
                        if (checkPlace == "placeselected") {
                            map.setCenter(place.geometry.location);
                            map.setZoom(15);
                            marker.setPosition(place.geometry.location);
                            marker.setVisible(true);                                
                        }
                    });
                }

Answer 1

It depends what your architecture is and how you want to store this data. You may simply want to store the user details and map settings in your database or have it stored in a session variable.

Answer 2

This will not done by simply javascript , I think you should store the user's map settings in database by using $.ajax() . So, next time when the user see the map then he will his last updated settings .
