Sorry to bother you guys, but I'm stuck with his problem for half a day.
I want to draw
poly line in OpenLayers using LineString object, so I've copied the example from documentation. It runs ok but i can't see the line on the screen
Code looks like this
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
var map;
var lineLayer ;
var points;
var style;
var polygonFeature
function test()
{
lineLayer = new OpenLayers.Layer.Vector("Line Layer");
style = { strokeColor: '#0000ff',
strokeOpacity: 1,
strokeWidth: 10
};
map.addLayer(lineLayer);
points = new Array();
points[0] =new OpenLayers.LonLat(-2.460181,27.333984 ).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());;
points[1] = new OpenLayers.LonLat(-3.864255,-22.5 ).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());;
var linear_ring = new OpenLayers.Geometry.LinearRing(points);
polygonFeature = new OpenLayers.Feature.Vector(
new OpenLayers.Geometry.Polygon([linear_ring]), null, style);
lineLayer.addFeatures([polygonFeature]);
alert("1");
}
function initialize()
{
map = new OpenLayers.Map ("map_canvas", {
controls:[
new OpenLayers.Control.Navigation(),
new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.LayerSwitcher(),
new OpenLayers.Control.Attribution()],
maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34),
maxResolution: 156543.0399,
numZoomLevels: 19,
units: 'm',
projection: new OpenLayers.Projection("EPSG:900913"),
displayProjection: new OpenLayers.Projection("EPSG:4326")
});
// Define the map layer
// Here we use a predefined layer that will be kept up to date with URL changes
layerMapnik = new OpenLayers.Layer.OSM.Mapnik("Mapnik");
map.addLayer(layerMapnik);
var lonLat = new OpenLayers.LonLat(0, 0).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());
map.zoomTo(3);
map.setCenter(lonLat, 19);
test();
}
</head>
<body onload="initialize()" >
<div id="map_canvas" style="width: 828px; height: 698px"></div>
I'm sure I'm missing some parameter in creation of map or something but I really can't figure which one.
