/* Always set the map height explicitly to define the size of the div 
 
     * element that contains the map. */ 
 

 
#map { 
 
    height: 100%; 
 
} 
 
/* Optional: Makes the sample page fill the window. */ 
 

 
html, 
 
body { 
 
    height: 100%;

你能澄清你的问题？你是否愿意知道你应该在哪里写你的坐标？ –

自动您的意思是**动态**权利？ –

那么你知道如何加载文件吗？ – epascarello

假设你的文件是location.txt，内容是这样的： lat;long，例如30.3434;30.234

你可以做你想要使用jQuery的：

function initMap() { 
    var myLat, myLng, myMap; 
    $.ajax({ 
     url : "location.txt", 
     dataType: "text", 
     success : function (data) { 
      var location = data.split(";"); 
      myLat=location[0]; 
      myLng=location[1] 
     }, 
     error: function(data) { 
      console.log("unable to retrieve data from location.txt") 
     }, 
     complete: function(data) { 
      //Called after success and error callbacks are executed. 
      myMap = new google.maps.Map(document.getElementById('map'), { 
       center: {lat:myLat, lng:myLng}, 
       zoom: 8 
      }); 
     } 
    }); 
}
