Javascript &引用；对象没有方法'；getBounds'&引用；OpenLayers中的错误

我正在使用此代码在地图上绘制一个点：

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);         
}

我从控制台收到此错误：

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

我做错了什么？

你的地图有“基本层”吗？否则，应将选项“alloverlays”=true添加到地图选项中。我不确定这是否解决了您的问题…

答案是添加多点几何体：

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(lon, lat));
            var pointsGeometry = new OpenLayers.Geometry.MultiPoint(coordinates);
            var pointFeature =  new OpenLayers.Feature.Vector(pointsGeometry, null, style_blue);

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

为了完整起见，我在从原始WKT数据添加多边形（不是点）时收到了类似的错误。由于对象的类型错误，因此出现没有边界的错误

当您调用

addFeatures

时，它需要一个由创建的对象数组

另外，尝试在gis.stackexchange.com上提问，您可能会在那里得到更好的帮助！我完全忘记了这个问题。你是对的，它是错误的对象类型。

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