我需要拖動標記在谷歌地圖

Question

我需要在谷歌地圖可拖動標記..

所以改變了代碼

VAR點=新的GLatLng（app.entries [ID] .data.lat，應用.entries [ID] .data.lng）;

var m = new GMarker（point，app.icon [app.entries [id] .data.icon]）;

到

VAR點=新的GLatLng（app.entries [ID] .data.lat，app.entries [ID] .data.lng）;

var m = new GMarker（point，{draggable：true}）;

我怎麼能找到標記的新位置..

Answer 1

我猜你缺少聽衆，如文檔中說明。

請看看這個例子：

var map = new GMap2(document.getElementById("map_canvas")); 
var center = new GLatLng(37.4419, -122.1419); 
map.setCenter(center, 13); 

var marker = new GMarker(center, {draggable: true}); 

GEvent.addListener(marker, "dragstart", function() { 
    map.closeInfoWindow(); 
    }); 

GEvent.addListener(marker, "dragend", function() { 
    marker.openInfoWindowHtml("Just bouncing along..."); 
    }); 

// to get the point of dragger. 
GEvent.addListener(markerD2, "drag", function(){ 
    document.getElementById("location").value=marker.getPoint().toUrlValue(); 
}); 


map.addOverlay(marker);
