Google지도 컨트롤러를 사용 설정하는 방법 (오른쪽, 오른쪽 화살표 등)

Question

내 위치를 검색하는 응용 프로그램을 빌드했습니다.

는 여기가 잘 작동 코드

var map; 
var gdir; 
var geocoder = null; 
var addressMarker; 

function initialize() { 
    if (GBrowserIsCompatible()) {  
     map = new GMap2(document.getElementById("map_canvas")); 
     gdir = new GDirections(map, document.getElementById("directions")); 
     GEvent.addListener(gdir, "load", onGDirectionsLoad); 
     GEvent.addListener(gdir, "error", handleErrors); 
     map.setCenter(new GLatLng(51.519853,-0.122566), 14) 
     var point = new GLatLng(51.519853,-0.122566); //CHANGE THESE COORDINATES 
     map.addOverlay(new GMarker(point)); 
     map.openInfoWindow(map.getCenter(),html) 
    } 
} 

function setDirections(fromAddress) { 
    gdir.load("from: " + fromAddress + " to: 51.519741,-0.122596 "); 
} 

function handleErrors(){ 
    if (gdir.getStatus().code == G_GEO_UNKNOWN_ADDRESS) { 
     alert("No corresponding geographic location could be found for one of the specified addresses. This may be due to the fact that the address is relatively new, or it may be incorrect.\nError code: " + gdir.getStatus().code); 
    } else if (gdir.getStatus().code == G_GEO_SERVER_ERROR) { 
     alert("A geocoding or directions request could not be successfully processed, yet the exact reason for the failure is not known.\n Error code: " + gdir.getStatus().code); 
    } else if (gdir.getStatus().code == G_GEO_MISSING_QUERY) { 
     alert("The HTTP q parameter was either missing or had no value. For geocoder requests, this means that an empty address was specified as input. For directions requests, this means that no query was specified in the input.\n Error code: " + gdir.getStatus().code);   
    } else if (gdir.getStatus().code == G_GEO_BAD_KEY) { 
     alert("The given key is either invalid or does not match the domain for which it was given. \n Error code: " + gdir.getStatus().code);  
    } else if (gdir.getStatus().code == G_GEO_BAD_REQUEST) { 
     alert("A directions request could not be successfully parsed.\n Error code: " + gdir.getStatus().code);  
    } else { 
     alert("An unknown error occurred."); 
    } 
} 

function onGDirectionsLoad(){} 

입니다. 하지만 탐색 키가 없습니다. 내가 활성화 할 수있는 방법은 무엇이든지 말해 줄 수 있습니다.

화면에 다른 팬 컨트롤 (예 : 일반적으로 Google지도에서 볼 수있는 네 방향 아이콘)을 넣으려고하는 경우, 이 control tutorial은 Google Maps Javascript API 버전 2입니다.

기본적으로이 링크는 어떤 상황에서 설명 할 수 있습니다. which controls automatically appear. 그러나 Google지도에 컨트롤을 적용하려면 다음과 같이하십시오.
