如何在OpenLayers中创建简单的可拖动标记 [英] How to create a simple draggable marker in OpenLayers

问题描述

一个非常简单的问题，我如何在OpenLayers映射中创建可拖动标记，并在拖动时获得拉特隆.从Google看来，您可以使用可拖动的矢量，但不能使用可拖动的标记.

Very simple question, how can I create a draggable marker in an OpenLayers map, and get the latlon when its been dragged. From google, it seems that you can have draggable vectors, but not draggable markers.

我已经看到了对OpenLayers.Control.DragMarker的一些引用，但这似乎不在核心"库中.在此示例中使用了它，但似乎正在使用一个自定义的OpenLayers JS文件，因此我不知道如何将其包含在我的代码中.

I've seen some references to OpenLayers.Control.DragMarker, but this doesn't seem to be in the "core" library. It's used in this example but that seems to be using a custom OpenLayers JS file, so I have no idea how to go about including that in my code.

到目前为止的代码(添加一个简单的标记):

Code thus far (to add a simple marker):

var layer = new OpenLayers.Layer.TMS( "TMS The Layer","",
    {  url: '', serviceVersion: '.', layername: '.', alpha: true,
        type: 'png', getURL: overlay_getTileURL 
    });

map.addLayers([layer]);


    var markers = new OpenLayers.Layer.Markers( "Markers" );
    map.addLayer(markers);
    var lonLat = new OpenLayers.LonLat( -100 ,100 );
    markers.addMarker(new OpenLayers.Marker(lonLat));

推荐答案

我已经做到了，但是现在找不到该代码.看看这个OpenLayers示例:

I've done that, but I can't find that code now. Take a look at this OpenLayers Example:
