javasrcipt如何把测量结果显示在几何对象的中心

Answer 1

    function measureDisCompleted(measureEventArgs) {
        var distance = measureEventArgs.result.distance.toFixed(2),
            str = '';
        if (distance != -1) {
            str = "距离:" + distance + "千米";
        } else {
        }
        if (map.getLayerIndex(labelLayer) == -1) {
            map.addLayers([labelLayer]);
        }
        map.setLayerIndex(labelLayer, map.getNumLayers() - 1);
        var label = new SuperMap.Geometry.GeoText(lonx, laty, str);
        var labelFeature = new SuperMap.Feature.Vector(label);
        labelFeatureList.push(labelFeature);
        labelLayer.addFeatures(labelFeature);
    }
