谷歌地圖初始化不能看地圖變量添加標記

Question

當我有一個谷歌地圖以下初始化：

function initialize() 
    { 
     var mapOptions = { 
      zoom: 15, 
      center: myLatLng, 
      mapTypeControl: true, 
      mapTypeControlOptions: { 
      style: google.maps.MapTypeControlStyle.DROPDOWN_MENU 
      }, 
      zoomControl: true, 
      scaleControl: true, 
      scrollwheel: true, 
      disableDoubleClickZoom: true, 
     }; 
     var map = new google.maps.Map(document.getElementById("googleMap"), 
      mapOptions); 
     } 

    var marker = new google.maps.Marker({ 
     position: myLatLng, 
     map: map, 
     title: 'Hello World!' 
     }); 

    google.maps.event.addDomListener(window, "load", initialize); 
    }; 

當試圖添加的標記，我得到的錯誤：

Uncaught ReferenceError: map is not defined

如何查看此地圖或向地圖添加標記？

似乎你沒有適合你的標記的myLatLng位置嘗試添加一個例如：myLatLng = new google.maps.LatLng（45.00，10.00）;

function initialize() 
    { 
     var mapOptions = { 
      zoom: 15, 
      center: myLatLng, 
      mapTypeControl: true, 
      mapTypeControlOptions: { 
      style: google.maps.MapTypeControlStyle.DROPDOWN_MENU 
      }, 
      zoomControl: true, 
      scaleControl: true, 
      scrollwheel: true, 
      disableDoubleClickZoom: true, 
     }; 
     var map = new google.maps.Map(document.getElementById("googleMap"), 
      mapOptions); 
     } 

    var myLatLng = new google.maps.LatLng(45.00, 10.00); 
    var marker = new google.maps.Marker({ 
     position: myLatLng, 
     map: map, 
     title: 'Hello World!' 
     }); 

    google.maps.event.addDomListener(window, "load", initialize); 
    };
