我需要Google地图中的可拖动标记 [英] I need draggable markers in google maps

问题描述

我需要在Google地图中使用可拖动的标记.

I need draggable markers in google maps..

所以我更改了代码

var point = new GLatLng(app.entries[id].data.lat,app.entries[id].data.lng);

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

到

var point = new GLatLng(app.entries[id].data.lat,app.entries[id].data.lng);

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

我如何找到标记的新位置.

how can i find the new position of marker..

推荐答案

我猜您按照文档中的说明缺少了侦听器.

I guess you are missing listeners as explained in the documentation.

请查看此示例:

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);
