Question

I’m using this code to draw a point on a map:

function addPointToMap(pMap){
    var coordinates = new Array();

    // Style Point
    var style_blue = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style['default']);
    style_blue.strokeColor = "blue"; 
    style_blue.fillColor = "blue"; 

    // Make Point
    coordinates.push(new OpenLayers.Geometry.Point(33, 33));
    var pointFeature =  new OpenLayers.Feature.Vector(coordinates, null, style_blue);

    // Layer
    var pointsLayer = new OpenLayers.Layer.Vector("Points Layer");
    pointsLayer.addFeatures([pointFeature]);
    pMap.addLayer(pointsLayer);         
}

I’m getting this error from the console:

Uncaught TypeError: Object POINT(33, 33) has no method 'getBounds'

What am I doing wrong?

Answer 1

For the sake of completeness, I received a similar error while adding a polygon (not a point) from raw WKT data. The error that there are no bounds occur because the object was of the wrong type.

When you call addFeatures, it expects an array of OpenLayers.Feature.Vector objects, which are created by Format.read.

var wkt_parser = new OpenLayers.Format.WKT();
var wkt_data_parsed = wkt_parser.read(some_raw_wkt_data_string);
layer.addFeatures([wkt_data_parsed]);
