是否可以仅将点移动到保存在数组中的位置?
我有位置数组,它表示地图上的路线。
allPathCoordinates = [ //array representing route
@foreach (var myitem in Model)
{
var dlat = @myitem.latitude;
var slat = dlat.ToString().Replace(",", ".");
var dlon = @myitem.longitude;
var slon = dlon.ToString().Replace(",", ".");
<text>new OpenLayers.LonLat(@slon, @slat),</text>
}
];
我将点设置为路线的起点,我只想将该点移至该路线。 我已经有了可拖动的点,但是可以将其移动到地图上的任何位置。
//create draggable point on map
var center = new OpenLayers.LonLat(longitude.ToString(),latitude.ToString()).transform(fromProjection, toProjection);
var point = new OpenLayers.Geometry.Point(center.lon,center.lat);
var vectors = new OpenLayers.Layer.Vector("Vector Layer");
map.addLayer(vectors)
vectors.addFeatures([new OpenLayers.Feature.Vector(point)]);
drag = new OpenLayers.Control.DragFeature(vectors, {
autoActivate: true,
onComplete: function() {alert('move!')}
});
map.addControl(drag);
map.setCenter(center, 15);
